Sonar Frequency Explained
Вставка
- Опубліковано 24 сер 2024
- This video gives and overview of which sonar frequencies to use under certain conditions. Higher frequencies do not always perform the BEST!!! Video examples are done on a Garmin UHD 93SV with a GT52UHD transducer depending on your sonar unit and transducer performance and options may vary.
NOTE: The cone angle image was found on the Northwest Fishing Reports blog posting, calculations were not verified. Used as reference to show increasing coverage area as the cone angle increases.

Great video! I do have a question, though I always see videos talking about frequency high and low shallow and deep water, but what's considered as deep and shallow water? Like, what should I have my frequency set on if I'm in, let's just say, 20-60 feet or 100 or more what's considered deep or shallow
It really depends on the transducer, the best resource I’ve found is the Garmin transducer selection guide. It will tell you the maximum depth at each frequency for each different transducer for clear vu and side vu, at 100’ you shouldn’t be too limited. Traditional will work well at all frequencies in those depths. I would start at the lower frequencies and work up. you can google it, easy to find
Thanks so much.
Gran master class de Garmin, lo malo es que soy español y no me entero de nada, si hubiera alguien como usted en españa seria de mucha ayuda, un gran saludo
Thanking you again. I retired this year and am kayak fishing off the California coast. I was able to get a Garmin UHD 74cv. I knew this could be a great unit, but never even got close to its potential til I found your site. You have a great knack of explaining and diagraming things so that a layman (truckdriver) can understand and put to use. I am enjoying my fishing success so much more now that I am beginning to understand what is under me. Thank you so very much.
That’s great!! I just got a Bonafide SS127 and fished a bass tournament in it. What a blast. I have some kayak videos in the que that will be rolling out on Saturday mornings for the next 4 weeks. Thank you for the comment, have a great day!!!
How Cool. You will enjoy the Yak. It is still fishing but in a way a different environment; so peaceful and quiet. You can get into new areas.
Agree, something about paddling I’ve always enjoyed. Simple, no stress.
I'm definitely going to check this out when I have time to comprehend it.
I need to educate myself on what the frequencies do.
Lower frequency penetrates farther in the water column and generally less detail. Much of the frequency and image detail is driven by the quality of the transducer. Thanks for watching and have a great day!
I watch you and mG marine tech and I have learned a lot thank you.
Max has a wealth of knowledge on his channel, I try to stay at the beginner level. If your not already watching go to the Russell Marine channel, they do a great job on product comparisons. Thanks for watching!!
This is an amazing video. I was trying to get a handle on how all the frequencies relate and this got it across to me.
That’s great!!! Hope you have a great season fishing
@@DoubleTFishing I just got the SideVu imaging and I am going have to work at it to understand what I am seeing.
It takes a little bit to gain trust in it. Go to the “fish the moment” channel and look at some of Johnny’s sidevu videos. There not Garmin but he does a great job of explaining how it works and interpreting what you are seeing. I use it mainly to find structure. A 9” screen is pretty hard to actually see fish.
Awesome video describing the differences. Super helpful for a new boater like myself. New subscriber here, keep up the great work!
Will do, have a great weekend!!
Great job, I'm a new beginner with echomap 94sv.
Appreciate the kind words Richard, have a great weekend!!
Good job brother sonar for Lehman I’ve got so much information from you just today watching these videos thanks
Your welcome Buddy, have a great day!!
Thanks so much for doing these videos I'm learning a lot.
That great!! Thanks for the comment, have a great day
Thank you very much from united Arab emirates to you ❤❤❤
Have a great day!!
Very informative,thank you.
Thank you, have a great day!!!!
Thank you for the lesson most interesting
I’ve been re-making some of the earlier videos and this one is on the list👍🏼. I liked the information but can definitely make a better quality video, thanks for watching. Happy 4th of July
I love your video lot of very good information at the moment I'm having trouble with mine it's the same 93 there my screen seemed to have his way too much junk running around and I don't know I can get rid of some of it or I'm stuck with it and that's just to start
You should be able to adjust your contrast or gain depending on which sonar screen your talking about (traditional or clear vu) to reduce noise clutter. If it’s vertical lines along the screen check that your power is above 11 volts, your ferrite bead is on your transducer cable and your not powered off your trolling motor battery. I have to adjust my brightness throughout the day for sunlight conditions but the gain and contrast I don’t mess with allot once they are set. If your transducer is getting air bubbles under it the picture is really bad. A little clutter isn’t a bad thing, I’ve been guilty of making the image so clear I’m missing the fish marks lol.
Great information thank you!
Glad it was helpful! thanks for watching
Great video!
Thanks, I appreciate that!!! Have a great weekend
so snapper trolling from 60 to 90 meters which frequency to use high chirp or medium chirp?
I’m not sure which type unit and transducer you are using and I’m definitely not a deep water angler but using traditional sonar with my Garmin ECHOMAP the high wide chirp transducer will reach almost 250 meters so I wouldn’t think you would be limited much and could use your higher frequency, now clear vu I can’t reach 90 meters according to the chart. I’d recommend looking at your transducer specifications to determine what frequency to try. The other method would be to start out at a high frequency and turn it down if needed until you get a clear image of the bottom. If you are running an ECHOMAP try that traditional split frequency screen and play around with that to make sure your seeing suspended fish correctly
My 73sv don't show flasher on the screen how do I set it where I can see it. Thanks Robbie
That’s odd? I have it on my home screen with the other sonar icons? Try building a combo and see if it gives you an option to add flasher. They hide the A-scope in the traditional. You have to open the traditional sonar, go into the menu then turn on A-scope to show the flasher on the side of the screen if that’s what your searching for? Have a great day Robbie. Send me a picture of your Home Screen doubletfishing@outlook.com
My GT54 doesn't allow me to change frequencies?
It only has 800khz in clear vu but you do have 455khz and 1120 kHz in side vu. The GT56 has more options.
@@DoubleTFishing My DI is 840.
I have an echomap uhd 93sv with GT54 trans, my khz options is 455 and 1120 , this is on side view , i didnt know this unit went to 1120 with GT54 , does that sound right ?
Mine shows it also after the latest software update!!!! Haven’t been on the water since the update, I’m excited to try it. I make the videos a couple months before they go online. I had a GT 52 most of last year, if I remember it was 840k hertz. Have a great day!
Where did u get the chart showing the cone angles along with the beam width at different depth
It was a northwest fishing report image on the web. Yep I cropped out the bottom with the source. I’ll put credit in the description, thanks for catch that!!!!
I was asking about the chart you showed. Good information. Can you provide the link to it would like to make copy to keep in boat
Yes, unfortunately it is an image so I don’t have a link but if you search “sonar cone angle coverage” in your web browser and select “images” it is a few pages down. If you do Instagram send me a message with you email and I’ll send you the image.
