Great video as always. For me Ocean is perfect for my level of diving, progress plans (future cerificates) and all day rounder. Especially, I don't have dive computer yet, this would be perfect first computer I think.
Thank you for the info! I just bought my first wireless wrist console. I looked at what you just showed, but I figured I would keep my everyday watch separate from my dive computer. Keep it simple!
I most definitely would pick the Suunto over the other two, 'cause I have the D5 from Suunto and I'm very satisfied with it's perfomance, so I guess the new one will be even better :)
I love my Suunto Ocean. I baucht it 2 month ago in Bundle with the Tank POD. Im very happy. I swithed from an Apple Watch and be so happy I did it. I love the Great battery life and the Fokus on Fitness/Sports and not on smart Features (I deactivated the Phone notification). I would buy it again.
Definitely the Suunto, as I'm on Android for my phone, and the price point is half that of the Garmin and good for all my recreational diving needs. The Garmin would be best for tech diving.
I am planning to buy the Suunto Ocean because of the following: 1) Simple slick design, no fuzz 2) I have dived with the Ocean and the AMOLED is really amayzing under water 3) I am not planning to gontec diving, so suited for my activities.
Thanks for the video. I was looking for a video like that, giving a complete view of the Suunto Ocean, which could be my first diving watch. Answering to the contest, I would pick the Suunto Ocean, because of its good value for many, and because it keeps information legible and simple, while still having air integration, a compass, etc. Also because I could use it for cycling and other outdoors activity. I don't mind for smartwatch features.
Thank you for the detailed comparison. I am new to diving and research gear. I am leaning to the Garmin Mk3i. But this gave me another everyday watch option to consider.
Bought a Suunto Ocean about a month ago, the product immediately presented the following problems: 1) sleep monitoring does not work; 2) absolute imprecision in detecting heartbeats; 3) imprecise GPS track on forest routes; 4) dive alarms barely audible. Finally, the Suunto writing engraved on the metal case was erased after just 30 days. When I contacted the assistance service they did not offer any valid alternatives either in terms of repair or replacement. Much better Garmin...goodbye
Sold my suunto for half the price i payed for it. Could not get more. Terrible watch. Bought the garmin fenix8. Everything is much better. I also got the MIP version. The amoled screen on the suunto was annoying.
I love and will always choose the Garmin mk3i it is tough reliable and allows for the tech level depth limits the 5 buttons also make controlling the computer very easy
Thanks for the Review. I am looking for a watch that accompanies me on all my sports. The Sununto would fit well for this and is also affordable. It may be my Christmas present.
If I was buying a watch style dive computer right now, I would 100 % go for the Garmin mk3. I purchased a new dive computer a few months ago and went with a Shearwater instead of the Garmin for budget reasons. I wear a different Garmin watch every day and use it for a wide range of activities. I just love their quality which is certainly also present in the mk3. My wife had the Apple Ultra 2 and for a dive computer it is like the most basic you can go. Fine for recreational dives, absolutely. But still not worth the money.
I would like to go for the Garmin but for my experience level and budget, I will be buying the ocean! It seems to be a great inbetween option. Thanks for the tips
It looks nice but I think I would go for the Tern TX as a wrist dive computer . I like the advance features for diving more than the on land functions of the Ocean
As a fairly new diver and not wanting to spend too much I was looking into the G1 as couldn't justify the Mk3 price so the Suunto looks like a good computer to go with. Thanks for the comprehensive review!
Personally the Garmin seems to be fit for literally every sport you can do adventurously. But the Suunto is perfect from just diving. I use the Apple Ultra 2 with Oceanic and it’s just simpler for me now. Btw I just finished my AOW last month. So still new to the Diving World. Thank you for the informative content!
@zackw7587 Not sure about global price: Garmin Fenix 8 900- 1200 USD Sunnto Ocean 800 USD Garmin mk3i 1700 USD Garmin Fenix is daily sport watch top for 24/h support and enterie co ecosystem
We just got the Fenix 8, so too late for this video unfortunately. A comparison video of smartwatches & dive computers is in the works at the moment. The Suunto Ocean is $900 and the Fenix 8 is over $1000 so it's actually more expensive.
@@DIVEindotcom glad to hear. Adding diving to its top sell universlal model like Fenix shows that now rec dive became normal sport whitch can be support by normal sport device. So there will be problem with selling basic dive computers just for dive.
Thanks for this comparison video. I would probably go for the Garmin Descent MK3i from these 3, though it is in an entirely different price category from the Suunto. I understand your video was a comparison of dive computers that also function as smart watches for daily wear, and for this, i think the garmin just looks more like a watch I'd wear everyday.
I would go with Suunto due to design and price (compared with the other two), as I have 50:50 need for dive and above water watch. If money would not be an issue, than Garmin wins in my opinion.
I’ve owned numerous Suunto computers. The cobra, cobra 3, spider, and mosquito. Thought they were all great, but it seems to me the functionality of the Garmin is just too good. I would choose the MK3, but I wouldn’t cry if I opened up the Suunto ocean on Christmas morning.
i would choose definitely the Garmin, and already did... have been using it since the mk1 and had all the descents so far. it is reliable and i trust it, just the compass thing convinced me Suunto are not what they used to be. Not to mention i use Garmin pay on daily basis and the music is a nice touch, also the dive maps are useful to some extent.
I'd go with the Suunto Ocean. It offers dive-specific features (+ AI), a sleek design and affordability. It delivers exactly what divers need without the high price tag of the MK3I or the more general-purpose focus of the Apple Watch Ultra.
Thanks for the videos on the Suunto Ocean, I ordered one yesterday and can’t wait to give it a try! I love Garmin (using a Venu 3 daily) but the Descent is both very expensive and to be honest, rather ugly.
I’d almost zeroed down on the MK2i, but your video has had me rethinking stuff (in a good way haha)! Still leaning towards mk a bit for the better dive log features though. Not to mention the much better compass on the mk vs the suunto
I have the Ocean, considered the Mk3 but it was just too expensive for me as a recreational diver. Ocean is a beautiful watch, although the OHR during land exercise is rubbish and a proper chest strap is needed. The Suunto app is kinda cool too for keeping track of weekly targets - e.g., cardio, strength, mobility, flexibility activities.
Personally i bought the garmin mk3i while choosing between it and the suunto, for which i could have had the wireless probe too for the same price. The turnaround point for me was the possibility to pay from the watch with no phone around
I feel like mk3i is currently in its own league. Above water, I’ve used garmin’s ecosystem for the longest time. They simply have the best day to day activities such as outdoor runs, etc. I can’t be diving all day everyday and I would be out of water doing my recreational activities and Garmin is the best platform for it
For me the overall capabilities of the Garmin MK3 is the one I am looking at. it is very expensive but seems really worth the price. The other dive computer I would like to see compared it the Atmos Mission 3.
I’ve generally leaded towards the Garmin, but the Suunto Ocean seems to be a better bang for the buck. I really like the ability to adjust the light. As a newer rec diver I would pick the suunto ocean over the mk3i because of price.
Im in between the Apple and the Suunto. The Apple is better as an everyday watch (I dive very little), but I really want the air integration and air time metrics from the Suunto as a safety concern for when I do dive.
i would pick the gamin mk3i, I'm thinking about moving into technical diving and the Garmin would give me place to grow as a diver. but for the place i am right now the Suunto also sounds amazing as a dive computer.
JUST got my first ever dive com - Suunto Ocean - before this video. Was genuinely struggling between Ultra, Mk3i, and Ocean but went with Ocean ultimately because: 1) price is more acceptable 2) Dive route tracking which is very impt to me 3) I’m just a newbie only got my AOW not long ago and generally don’t get to dive frequently so I don’t need something technical (Mk3i) but at the same time the thought of requiring an App just to dive is quite annoying (Oceanic app with Ultra). Haven’t gone for a dive to test the watch but am excited to try it! Perhaps as I acquire my skill sets and get more technical, might consider Garmin descent series in the future!!
We found that the Suunto fit great into this middle ground of not too technical but still very capable. It sounds like it'll fit your needs well. It'd be great to hear back from you when you get it wet. Got any dives booked/coming up?
I'll go for fenix8. I do own suunto d4i and suunto 9 baro. I want to have only 1 watch. Fenix 8 also supports 515 radar rear light and it has garmin pay.
One of the big reasons to go for the Suunto ocean for me is because of the easiest readable screen. Elderly divers like me don't have the perfect reading ability anymore. As a recreational new diver the price - specifications balance is the second reason to go for Suunto ocean.
What I learned looking at the manuals is, that compared to the Garmin, the Suunto will give you much clearer and unmistakeable instructions when you screwed up and need your dive-computer to actually save your life underwater. For me, that's a big plus.
An air integrated dive computer that does NOT let you see/show your remaining air pressure at all times (e.g. when using the compass, or viewing other data) is a deal breaker for me. Absolutely NO customization option of the dive screen on the Suunto is a great oversight, and would have been so easy to add as it is just a software issue. I understand they went for simplicity, but they overdid it and compromised safety imo. Although much more expensive, Garmin Mk3i all the way. If you don't want air integration, I would go for the Garmin Fenix 8 (which works for scuba down to 45m).
It is a very difficult decision, Garmin or Suunto. Apple is not an option - because Apple. In favour of Garmin, especially mk3, is the fact that they also have the 43mm version. On female wrists, 51mm looks over-deminised. For this reason, I decided in favour of the Garmin. Even though I have had Suunto dive computers before and know that they are very simple and easy to understand.
Does this Suunto model still have the overly conservative algorithm that makes it beep endlessly during a simple recreational dive, leaving you as the last one out of the water?
No, the Suunto is using the Bühlmann ZHL-16C Algoritme with gradient factors, meaning that it uses the same algoritme as most other serious dive computers.
Suunto or Garmin, because I love swimming and scuba diving. At the moment I use two different watches, but it would made much more sense to got one which is great at both. 🫶

I am a Suunto type. And as a scubadiver, freediver and ambitious hiker I see a huge possability in the Ocean.
Love the video, super clean to me.
I would go for the ocean, I am a great fan of suunto.
Special the gps looks great to me.
Thanks for all the great info as usual!
Great video as always. For me Ocean is perfect for my level of diving, progress plans (future cerificates) and all day rounder. Especially, I don't have dive computer yet, this would be perfect first computer I think.

I like the simplicity of the suunto
I just got an ocean and I like it so far. Taking it diving this weekend.
I would go for Garmin MK3i. The ecosystem for everything not diving related plus the best dive rating makes it a definite winner for me!!
No comparable. The price difference is huge!
I most definitely would pick the Suunto over the other two, 'cause I have the D5 from Suunto and I'm very satisfied with it's perfomance, so I guess the new one will be even better :)
D5 ist fantastisch der Nachfolger Wird der Ocean in 2 Jahren
I love my Suunto Ocean. I baucht it 2 month ago in Bundle with the Tank POD. Im very happy. I swithed from an Apple Watch and be so happy I did it. I love the Great battery life and the Fokus on Fitness/Sports and not on smart Features (I deactivated the Phone notification). I would buy it again.
Definitely the Suunto, as I'm on Android for my phone, and the price point is half that of the Garmin and good for all my recreational diving needs. The Garmin would be best for tech diving.
I’ve been looking at the Garmin but the Suunto looks like a better choice for my life in general.
I am planning to buy the Suunto Ocean because of the following:
1) Simple slick design, no fuzz
2) I have dived with the Ocean and the AMOLED is really amayzing under water
3) I am not planning to gontec diving, so suited for my activities.
I tried with MK3i side by side, i have +1 Eye. I could not read Suunto Ocean numbers. While MK3 its big font really helps.
Thank you. That's a big plus for me and my old eyes😂

Welp, that did it for me. Staying with Shearwater.
There are new updates that correct bugs. The watch is very new and still need to be corrected. The MK3 is a good watch but it is worth 2 times more.
I love and will always choose the Garmin mk3i it is tough reliable and allows for the tech level depth limits the 5 buttons also make controlling the computer very easy
I would love to see a review between the Suunto ocean and the shearwater tern
Thanks for the Review.

How much garmin Is paying you?
@ haha I wish they were paying me (in watches) :D
I would like to go for the Garmin but for my experience level and budget, I will be buying the ocean! It seems to be a great inbetween option. Thanks for the tips
I would love the Garmin Mk3, seems like the most future proof option
Thanks for the review
For me i would take the MK3i about all capability for side mount and tec
It looks nice but I think I would go for the Tern TX as a wrist dive computer . I like the advance features for diving more than the on land functions of the Ocean
For me it is the Suunto! Beautiful, simple, well made and way more affordable than the Garmin

The mk3i would be my choice.
Had the Fenix 5x and now useing the Fenix 7x.
I just really like Garmin 😁
You missed important market change. Garmin now has Fenix 8 (much cheaper ) as recreational dive computer ...
Didn't hear about that.. lack of AI makes it seem overpriced tho.. no?
@zackw7587 Not sure about global price:
Garmin Fenix 8 900- 1200 USD
Sunnto Ocean 800 USD
Garmin mk3i 1700 USD
Garmin Fenix is daily sport watch top for 24/h support and enterie co ecosystem

I've always liked Suunto and the Ocean looks like the best option for me, for visibility and multiple uses in addition to the dive computer.
Owned a shearwater tern tx, have been looking for a new one for my friends, Suunto Ocean seems get the sweet spots!
I want the Suunto as the cost and usability matches my diving and surface life.
Thanks for this comparison video.
I would probably go for the Garmin Descent MK3i from these 3, though it is in an entirely different price category from the Suunto.
I understand your video was a comparison of dive computers that also function as smart watches for daily wear, and for this, i think the garmin just looks more like a watch I'd wear everyday.
As a new prof in the sport i would go with the Garmin Mk3i. Just the allround use of it compared with the extended batterylife does it for me.
I would go with Suunto due to design and price (compared with the other two), as I have 50:50 need for dive and above water watch.
If money would not be an issue, than Garmin wins in my opinion.

Have you used the feature that enlarges the size of the data? I have not seen it in person.
@@cleanlife1305 es, it is quite good. but i prefer it the default size as you can fit more data in the screen
I'd go with the Suunto Ocean. It offers dive-specific features (+ AI), a sleek design and affordability. It delivers exactly what divers need without the high price tag of the MK3I or the more general-purpose focus of the Apple Watch Ultra.
Suunto ocean cos it looks stylish!
I have had Suunto Ocean in my shopping cart waiting for black friday for a month now :P
Same 😂
Really want a watch ⌚️ that can do it all that involves diving and the stream line the information that's why I think the mk3i is the best option.

For diving only Suunto it’s safer
Cheers from France

They simply have the best day to day activities such as outdoor runs, etc. I can’t be diving all day everyday and I would be out of water doing my recreational activities and Garmin is the best platform for it
Good looking dive computer/watch, but it falls into a weird space between the Apple watch Ultra and Descent MK3i.
For me the overall capabilities of the Garmin MK3 is the one I am looking at. it is very expensive but seems really worth the price. The other dive computer I would like to see compared it the Atmos Mission 3.
i would go with the garmin

I’d take the Suunto Ocean because of the underwater route tracking. The price makes it more preferable for me than the MK3i.
I'll go for fenix8. I do own suunto d4i and suunto 9 baro. I want to have only 1 watch. Fenix 8 also supports 515 radar rear light and it has garmin pay.
Can you please give us your opinion or make un report for HUAWEI ultimate. Thanks for your help .
I would choose Suunto Ocena for my travel dive computer, because is bigger than Apple and cheaper than Garmin.
I would choose de Garmin MK3i, becouse it's the only one from the 3 that can let me grow in my dive adventures
i would buy the suunto ocean just because i think it has a better price per performance value
As a recreation diver i prefer the suunto ocean for it's price as a guy who loves these type of watces i would prefer the mk3
One of the big reasons to go for the Suunto ocean for me is because of the easiest readable screen. Elderly divers like me don't have the perfect reading ability anymore. As a recreational new diver the price - specifications balance is the second reason to go for Suunto ocean.
I have an ocean. The hardware is amazing, but the firmware requires a lot of updates.
I would choose sunnto ocean, all in one device for my activities😅
Good to see Suunto coming back, but at this point in time, I am too far invested in the Garmin ecosystem
What I learned looking at the manuals is, that compared to the Garmin, the Suunto will give you much clearer and unmistakeable instructions when you screwed up and need your dive-computer to actually save your life underwater. For me, that's a big plus.
An air integrated dive computer that does NOT let you see/show your remaining air pressure at all times (e.g. when using the compass, or viewing other data) is a deal breaker for me.

No, the Suunto is using the Bühlmann ZHL-16C Algoritme with gradient factors, meaning that it uses the same algoritme as most other serious dive computers.
I'm paying? Then probably Suunto. If someone wants to buy me the Garmin though ... 😄😄
iWatch ultra 2
I already have another garmin so I lean garmin
Short answer... No, not by a long shot.
They think will kill garmin with 60M depth.. 🤣🤣
The end of suunto ocean is Huawei watch ultimate.
I bought them new for 350 usd .
suunto ocean invasion of privacy!!!!!!!!!!!!!!!!!!!!
Suunto or Garmin, because I love swimming and scuba diving. At the moment I use two different watches, but it would made much more sense to got one which is great at both. 🫶
