I am aware that longer rubber guns are more accurate and powerful than the short one i have in this video. However, pneumatic guns were designed to replace rubber guns a long time ago because there are many other disadvantages with them as well. Rubber guns have planned obsolescence where all the parts are designed to wear out, especially the rubbers and wishbone which need to be replaced regularly. The spear is thinner and more easily bent, which would make it impossible to track straight. They are harder to aim because the loading butt conflicts with your vision of the target. The trigger mechanism is open to the water and rusts over time. The pull on the shaft from the rubbers is asymmetric (on top not the middle) and it only pulls the shaft about half way down the gun before it disengages. When the spear leaves the gun it has actually been decelerating for half a meter or more, making it very inefficient. The larger muzzle on rubber guns allow for a larger variance in where the spear shoots, and less accuracy. Also, physics of the rubbers acceleration is counter to the physics of the inertia of the spear. The rubbers' power decreases as it recoils. Whereas the spear needs the power to increase as it accelerates. Therefore most of the rubbers' energy is lost overcoming the inertia of the spear rather than accelerating it to a high muzzle velocity. Which is again very inefficient. This is why compound bows reverse this physics with the use of cams to apply more force as the arrow accelerates. Manufacturers know this, and rubber guns need to be much longer than pneumatic ones to try to offset the power and inaccuracy issues - putting you so close to the fish that you can't miss. But for me at least this becomes impractical for manoeuvring in the kelp and tracking fish with one hand. Pneumatic guns overcome all these issues as are accurate enough to spear bait-fish no more than 2cm high. They are a significant step forward in technology and you are being conned into thinking anything else. People will make more money off your buying spearguns that are more expensive and need more maintenance, and this is why they are more popular with suppliers. But go ahead if you want to be conned, more fish for me anyway. I'm just trying to help the newbies get more out of the sport.
it is also easier to mount an action cam / go pro on a pneumatic speargun as you can just use a velcro strap and put it wherever you want on the barrel. With band guns you need to buy a dedicated bracket that is usually $40 or 50 .
could you tell me the effective range of a smaller size pneumatic like 50cm? i am about to buy one and i want one with comparable range to my 60cm band gun.
@@Francois_Dupont My formula is about 4x the length off the gun from the end of the gun. 50cm gun is about 2m from the guns end. Plus your outstretched arm and the guns itself. About 3.5m. 1m gun about 4m plus the gun and your arm, so a out 5-6m from your eye. Get another meter with a vacuum gun.
Awesome review. I am new to spearfishing, and just ordered a Salvimar Predathor Storm 55cm pneumatic gun, and looking forward to using it this weekend. Thanks for the tips
Incredibly useful information. Thank you very much it comes to a guy from New Zealand to actually tell the world how to Spearfish:-) I have just purchased my second spear gun and it was a Pneumatic because I listened to what you said
@@robertjalu6897 ok sure. Yeah dont worry about too thick a shaft. I shoot a lot of small fish and its fine. I do highly recommend the 3 or 4 prong trident however. You will find it very easy to shot those small fish with them. And contrary to what you might think, they do not get off the trident once speared through. I use them most of the time now because it is so much easier to hit them because the trident is a much larger striking surface - make the target area much bigger.
If you try a rail gun where the spear is supported on the barrel along the length you should find them to be quite acuate and if you have dynema wishbones instead of metal wishbones then you end up with better power and accuracy and if you add rollers into the mix then you do get power all the way to the end of the gun. Also when it comes to ease of loading you can load a far more powerful rubber powered gun than the pneumatic equivelent because you can load bands seperatly.
Although a roller railgun may cost twice the price of a pneumatic, and you have to replace the bands every year as they lose elasticity and power. With the pneumatic you just need to add some oil. The O rings and the piston you may change after a few years seem quite cheaper than a roller gun band.
Its unlimited. It doesnt loose any air each time. It is a totally sealed system, using a piston to push out the spear. Its loaded with the spear against the amount of pressure you put in - which can be tailored to your specific needs.
thanks for the video mate, I'm just a self taught weekend warrior so I'm not too clued up on guns. I've got a pneumatic mares cerano 90 and was tossing up on getting a rubber gun as most people use them so i thought maybe they're better... think ill stick with the cyrano now! cheers!
Thank you! I had that Beuchat band gun. You can not put a 2nd sling on that because the trigger mech is made of plastic. It may misfire if you put 2 bands or a stronger band. Only higher grade band guns with metal trigger mech can be used with extra bands. I switched to pneumatic guns (Salvimar Predathor). I agree with your points. Also if you miss the shot, you can reload a pneumatic gun without wrapping the line and shoot again. Wrapping the line with an open muzzle band gun in surf or current can be more challenging. Another advantage is that you can use a simple velcro wrist mount to attach an action camera to the band gun, rather than expensive brackets for band guns. Also the rubbers of a band gun start degrading when exposed to air, and some say they need to be replaced yearly, while with a band gun you may just need to add some oil. Parts for pneumatic guns, like pistons and seals are quite cheap, under $10 on EU websites. It may be worth to order oil, shaft washer and dampening springs and so one when you order a gun. Did you buy a special loader for the 100cm gun? I have no problem loading my 65cm Salvimar using my knee for support, but i wonder if a 100cm gun, using the foot asa base may be trickier. Also do you need to depressurize your speargun if you travel by air with it in your checked baggage (mine came pressurized from Subprof, they shipped by UPS air, but I assume cargo plane)
Glad you have found the benefits of the pneumatic gun. I have shot a hell of a lot of fish over the summer and would never go back to the banded ones. Once i shot 2 fish in the head with one shot - killing both instantly. Yeah you are supposed to de-pressurise them when flying, but you can get away with it without any incident. The 100cm guns are fine for loading off your foot. The first few times i did it while standing up in shallow water with my foot on the bottom. but i got the hang of it and now its easy for me. I did however let a little of the air out of the gun to make it easier to load - maybe 2bar or so. It is still lethal to about 6m - which is beyond the limits of visibility and accuracy for small fish anyway.
Pneumatic i love them too since no rubber to change, tangle with the line or rubber breaks, rubber band guns are the best but they sometimes are annoying to load when open muzzle, pbeumatic i find them easier to load if you know how and if you have a fork attached its even easier, both have their advantages and disvantages
Its pretty easy. You just screw the pump into the back of the gun and begin pumping. There is a plastic cap you need to remove first that keeps the water out. You can custom pressurise the gun to whatever suits you and your needs. If you are shooting short distance or want it easier to load you just release a bit of air and test it. Anything up to 20bar.
Absolutely not! They come pressurised with 20bar when you buy them, and will pretty much last for the life of the gun. You do not loose any air when you shoot. The air just acts as the spring in a closed system. That means it takes 20bar of your arm strength to load it (and it might then be about 20.5bar) and it shoots with 20bar pressure. You only need to pump the gun up again if you let some gas out to customise it - e.g. if you lend it to a girl to use and want to make it easier for them to load. Its about 200 pumps from flat on the small (50cm) gun, and about 480 I think on the 1m gun.
Paul Garbett Variety Channel .am i right to say that everytime you shot.you can just shot immediately. Im just confuse coz i saw a video where he pump the speargun under water.
I bought it from a guy in NZ privately. I'll have a look for a link, but in the meantime have a look at Scubastore.com, spearguns, pneumatic spearguns as there are some really good short ones there for cheap - like the salvimar predator.
It comes pressurised when you buy it. But you can tailor that to suit how strong you are by either letting the air out or using the provided pump to add pressure. For example i let the air out for my female friend to use so its easier for her to load. The air just acts as a spring on a piston and you don't lose any when you shoot. So i just sort it at the start of the season. My cressi has not needed any maintenance or additional air since i bought it.
@@owenthomas9863 Yes thats right totally adjustable. I have a smaller one (50cm) that I use for all sorts of things and I adjust the power accordingly. As a flounder spear. For taking head shots for big fish once speared. I even set it up to try and shoot fish from the air and practiced on a tree stump. So yeah whatever power you want from quite extreme to mild out of the water applications.
It could be the recoil of the gun making you shoot high. if you are consistently shooting hi you need to hold the gun a lot tighter in your hand or you can try holding the gun side on gangster Style.
It is possible to order these in. But I doubt you'll need these as pneumatic guns can go for years without maintenance. I recommend the longer pneumatic guns of 75-100cm as they have great accuracy and range. Easy to load and operate and move around in the water.
pnumatic spearguns are good and I've got a 60cm and 100cm top of the range. But the accuracy of a longer band gun is much better and if you struggle loading it get twin 14mm bands on a 90cm. then tell me what you prefer. comparing anything to that shitty starter band gun is silly
how long the band gun you are using for the comparison on accuracy? Compactness is a factor as well. harder to travel with a long speargun. a 70 cm pneumatic would fit in most travel duffel bags, while a long band gun requires oversize bags it may cost you extra to have checked in.
Can someone clearly and positively verify that pneumatics are more powerful at the 0 - 15 meter zone ? Because I have seen videos with reloading long pneumatics where the guy pushes the spear into the pneumatic gun with one hand. Which is impossible to do with rubbers, you definitely need both arms for all rubber guns. And another thing = since pneumatics require maintenance, how much is the maintenance, how long does it take, and how often should it be done ? (on average)
Pneumatics do not require any maintenance at all for at least a number of years. After which it might pay to put a bit of baby oil in them to lubricate which takes about 2mins. Other than that they are maintenance free for maybe 10-20 years, or more. They use compressed air up to 290psi which pushes the spear through the entire length of the gun. i.e. my 1m gun accelerates the spear with 290psi for 1m. The actual spears are thicker and heavier as well (they do not get bent). They are usually too powerful to use - as mine will go for 5-6m regardless of what it hits. It always goes straight through the fish and out the other side often hitting other fish and going straight through those as well. They are very powerful and dangerous guns. Hence i have let air out of mine to decrease the power and make it easier to load (with one hand). You can tune the gun to whatever pressure you want anywhere between 0-20bar (0-290psi). Rubber guns require significantly more maintenance, especially the rubbers, which should be replaced every season. If you think through the physics of it, the rubbers only accelerate the spear in the extreme end of their stretch, after which their energy is spent, and the remaining recoil does not transfer any additional energy into accelerating the spear. So it might be difficult to load with rubbers, but remember that this only accelerates the spear for a short distance. Whereas the compressed air pushes the spear with full power until it leaves the gun.
If you are wondering, most people don't use pneumatics because most people don't understand how they work or why the physics of them is so effective. It is because of misunderstanding, not because they are inferior. As i have often said, they were invented to overcome the shortcomings of rubber guns in terms of maintenance, accuracy and power. Popular is seldom the best.
If you watch this video = ua-cam.com/video/bSnih61CD54/v-deo.html you will see why they need maintenance = a lot of dirt inside, plus there are plastics and o-rings that need cleaning and/or replacement. And I would certainly not use this for 10-20 years straight without maintenance. Perhaps you do, but this is a personal choice and not the general rule. (I do not own a pneumatic gun).
A pneumatic speargun may need to be opened up to be cleaned if dirt gets in there through a dirty spear or being dropped in the mud or something. But this is easy enough to avoid in my opinion. You would be able to tell its dirty by a grinding or sticking of the spear when you insert it. None of my guns have ever had this or needed cleaning, despite being in the sand a lot. So i wouldn't worry about it. I don't imagine the trigger mechanism on a rubber gun would do very well if it was full of sand or mud, but people don't use that as an excuse to avoid them - which is a double standard.
This is simply not true. Even a diving watch needs servicing, and it does not have moving parts or 30 atm inside! For example, visit mares.com, Downloads, Manuals and read the pneumatic spearguns manual. It recommends servicing every year. The gun contains high pressure oiled piston, o-rings and numerous other components, many of them are rubber and plastic and definitely need regular replacement.
This is another case of people blindly following whoever they look up to, as this sort of reverse logic does not address the various merits of the guns in question. Remember that pneumatic guns were invented by elite spearfishermen to overcome the limitations they had with the rubber guns.
There are Italians using them. And a Greek that I know that he replaced a dozen of rubber band ones with pneumatic youtube.com/@manolisgiankos?si=mh7at99GiHl8hxKn
Must be a kiwi thing, all 3 of my dive shops have both types. Good video, I think imma buy a short compressed one so everyone knows I'm not compensating for anything XD
They come precharged when new, but you can add air using a pump. The air acts as a spring into which you push the spear, and it shoots it out when triggered. No air is lost so you have an infinite number of shots.
All pneumatic guns are infinite shots nowadays. Back in the day there were different types. Some even CO2 powered. But yeah, the air just acts in place of the spring, so it takes a lot of force to load these.
Not real sure how long you have been spearing but you failed to mention the bad side of the pneumatic guns while you just sat there bashing the band guns. the truth of the matter is pneumatic has been around since the 60's they are out of favor with the hardcore speros because of the laws of physics. the deeper you dive the more power you loose. Where as band guns still have the same amount of power at 40 meters as they do at the surface. Do the sport a favor and research what your saying before you prove your ignorance. also the little pos aluminum band gun you have was never accurate and if your really using "The Sights" your nuts.. Spearguns are by nature shot instinctively just like shotguns, the so called sight isnt a sight. its nothing more than a visual to aid as you track your target. If your using it to aim like a rifle you will never learn to hit anything. I have been able to hit salmon in the eye consistantly with my american 30in wood speargun at 2 to 4 meters. its called Practice!
For every 10 meters (2 atmospheres) you dive you lose 1bar of pressure off the pneumatic gun, as the outside pressure increases and reduces the relative power of the compressed air inside the gun. However, with 20bars of pressure in your gun you can afford to dive about 100meters before the gun is at half power and more akin to the performance of a banded gun. I have a Master's Degree in Chemistry so i think i understand the effect of pressure thank you. I suggest that people who are starting out looking for advice on what gun to buy are not diving deeper than 100m to spear fish - but if they are then i'm sure they'll take your comments into consideration. Note: most the fish to spear here in Otago are in the top 5 meters of the water column, because they feed off the kelp, which needs sunlight (this leaves you with 19.5bar or 283psi pressure at 5m).
Thats true. Im using a Mares Cyrano HF 110 and the guys at the local dive shop look at me like I have two heads when I say I like using pneumatics. They always say how deep do I dive? I can go about 12m so far and I haven't notice any lack of power. They're great in my opinion. Better range, power and accuracy. The biggest con I could hold a candle to is, the noise. But then again, Ive been hitting pretty much all the fish I shoot at and Im not concerned about scaring off the fish my mates are going for because Im a fucking asshole.
The banded guns can make a lot of noise as well - depending on the gun. For some reason, there is a lot of peer pressure to get the banded guns and i'm not sure why. People look at me strange as well, but i'm hitting everything this summer. Regardless of what people say, there has been a huge increase of fish on our table because of the new pneumatic gun, and I am very pleased about that.
I feel you man. Since Ive used one ill never look back. They really are better but possibly a wee bit louder. But i dont care about that. Anyway, nice video.
I have known people who spent $500 on a rail gun and still had major problems with accuracy - shooting only 1 of 3 fish they shot at. So I don't recommend them for the price.
that Cressi pneumatic gun is probably less than 200 dollars, and you do not need to replace the bands every year like with a roller gun. How much is the cost of spare bands for roller guns?
Can Anybody help me truly understand what bands are best for my Salvimar 85cm K-pro; the original rubbers with the gun are almost useless now. I also have a rail on the bottom.

I'm hitting palm size fish from 5 meters 9/10 times with 75cm Cressi Comanche. I consider it a very accurate gun.
First off what are you doing shooting palm size fish?
I do freshwater. Some times palm size is all I get. :)
Can u demonstrate how to pressurize the pneumatic speargun
Its pretty easy. You just screw the pump into the back of the gun and begin pumping. There is a plastic cap you need to remove first that keeps the water out.

Hence i have let air out of mine to decrease the power and make it easier to load (with one hand). You can tune the gun to whatever pressure you want anywhere between 0-20bar (0-290psi). Rubber guns require significantly more maintenance, especially the rubbers, which should be replaced every season. If you think through the physics of it, the rubbers only accelerate the spear in the extreme end of their stretch, after which their energy is spent, and the remaining recoil does not transfer any additional energy into accelerating the spear. So it might be difficult to load with rubbers, but remember that this only accelerates the spear for a short distance. Whereas the compressed air pushes the spear with full power until it leaves the gun.
If you are wondering, most people don't use pneumatics because most people don't understand how they work or why the physics of them is so effective. It is because of misunderstanding, not because they are inferior. As i have often said, they were invented to overcome the shortcomings of rubber guns in terms of maintenance, accuracy and power. Popular is seldom the best.
If you watch this video =
ua-cam.com/video/bSnih61CD54/v-deo.html
you will see why they need maintenance = a lot of dirt inside, plus there are plastics and o-rings that need cleaning and/or replacement. And I would certainly not use this for 10-20 years straight without maintenance. Perhaps you do, but this is a personal choice and not the general rule. (I do not own a pneumatic gun).
A pneumatic speargun may need to be opened up to be cleaned if dirt gets in there through a dirty spear or being dropped in the mud or something. But this is easy enough to avoid in my opinion. You would be able to tell its dirty by a grinding or sticking of the spear when you insert it. None of my guns have ever had this or needed cleaning, despite being in the sand a lot. So i wouldn't worry about it. I don't imagine the trigger mechanism on a rubber gun would do very well if it was full of sand or mud, but people don't use that as an excuse to avoid them - which is a double standard.
This is simply not true. Even a diving watch needs servicing, and it does not have moving parts or 30 atm inside! For example, visit mares.com, Downloads, Manuals and read the pneumatic spearguns manual. It recommends servicing every year. The gun contains high pressure oiled piston, o-rings and numerous other components, many of them are rubber and plastic and definitely need regular replacement.
Knowing that pneumatic guns are not used by any professional spearman tells a lot about how bad they are.
This is another case of people blindly following whoever they look up to, as this sort of reverse logic does not address the various merits of the guns in question. Remember that pneumatic guns were invented by elite spearfishermen to overcome the limitations they had with the rubber guns.
There are Italians using them. And a Greek that I know that he replaced a dozen of rubber band ones with pneumatic youtube.com/@manolisgiankos?si=mh7at99GiHl8hxKn
Must be a kiwi thing, all 3 of my dive shops have both types. Good video, I think imma buy a short compressed one so everyone knows I'm not compensating for anything XD
How do you add air into Pneumatic Guns if you are snorkeling ? if you cant how many times can you shoot with it
They come precharged when new, but you can add air using a pump. The air acts as a spring into which you push the spear, and it shoots it out when triggered. No air is lost so you have an infinite number of shots.
Paul Garbett Variety Channel lol... I thought that you pump air on the gun for every shot!
All pneumatic guns are infinite shots nowadays. Back in the day there were different types. Some even CO2 powered. But yeah, the air just acts in place of the spring, so it takes a lot of force to load these.
first item is a pole spear, not a Hawaiian sling
that is not a hawian sling its a pole spear
Mares spersten 100 awesome
Roller speargun is accurate and very little recoil.
Not real sure how long you have been spearing but you failed to mention the bad side of the pneumatic guns while you just sat there bashing the band guns. the truth of the matter is pneumatic has been around since the 60's they are out of favor with the hardcore speros because of the laws of physics. the deeper you dive the more power you loose. Where as band guns still have the same amount of power at 40 meters as they do at the surface. Do the sport a favor and research what your saying before you prove your ignorance. also the little pos aluminum band gun you have was never accurate and if your really using "The Sights" your nuts.. Spearguns are by nature shot instinctively just like shotguns, the so called sight isnt a sight. its nothing more than a visual to aid as you track your target. If your using it to aim like a rifle you will never learn to hit anything. I have been able to hit salmon in the eye consistantly with my american 30in wood speargun at 2 to 4 meters. its called Practice!
For every 10 meters (2 atmospheres) you dive you lose 1bar of pressure off the pneumatic gun, as the outside pressure increases and reduces the relative power of the compressed air inside the gun. However, with 20bars of pressure in your gun you can afford to dive about 100meters before the gun is at half power and more akin to the performance of a banded gun. I have a Master's Degree in Chemistry so i think i understand the effect of pressure thank you. I suggest that people who are starting out looking for advice on what gun to buy are not diving deeper than 100m to spear fish - but if they are then i'm sure they'll take your comments into consideration. Note: most the fish to spear here in Otago are in the top 5 meters of the water column, because they feed off the kelp, which needs sunlight (this leaves you with 19.5bar or 283psi pressure at 5m).
Thats true. Im using a Mares Cyrano HF 110 and the guys at the local dive shop look at me like I have two heads when I say I like using pneumatics. They always say how deep do I dive? I can go about 12m so far and I haven't notice any lack of power. They're great in my opinion. Better range, power and accuracy. The biggest con I could hold a candle to is, the noise. But then again, Ive been hitting pretty much all the fish I shoot at and Im not concerned about scaring off the fish my mates are going for because Im a fucking asshole.
The banded guns can make a lot of noise as well - depending on the gun. For some reason, there is a lot of peer pressure to get the banded guns and i'm not sure why. People look at me strange as well, but i'm hitting everything this summer. Regardless of what people say, there has been a huge increase of fish on our table because of the new pneumatic gun, and I am very pleased about that.
I feel you man. Since Ive used one ill never look back. They really are better but possibly a wee bit louder. But i dont care about that.
Anyway, nice video.
You have to aim a shotgun . With a ramp rib and bead
Buy a good quality rail gun and you will be dead on like a rob Allen and get a nonger gun like 80cm up woods to 110cm not that pissy little rubber gun
I have known people who spent $500 on a rail gun and still had major problems with accuracy - shooting only 1 of 3 fish they shot at. So I don't recommend them for the price.
that Cressi pneumatic gun is probably less than 200 dollars, and you do not need to replace the bands every year like with a roller gun. How much is the cost of spare bands for roller guns?
Can Anybody help me truly understand what bands are best for my Salvimar 85cm K-pro; the original rubbers with the gun are almost useless now. I also have a rail on the bottom.
Are the SEAC pneumatic guns any good?
I believe so. I haven't heard anything to the contrary.
