Garmin Descent Mk3 Watch Style-Dive Computer, 43mm, Steel with Fog Gray Band

It took me not less than a week to revise all the options on the market, this watch is any other is a bit complicated to use, the instruction is like a Harry Potter book, but it is really very useful that works perfect according to its main target - Diving and Freediving

I love the feel of this watch. I have a feeling though it’s not as accurate as the newer Garmins when it’s calculating swim distance, but overall, it’s great and it costs much less than the other higher end Garmin dive watches. The dive functions works well, I just have never compared it to other more expensive dive watches.

HR ability ceased to work after slightly more than one year of use. During sprints, despite being able to easily palpate radial pulseof 165, garmin tells me my HR is 30-75. Recurrent issue. No damage to watch. Nomal daily use. No return no refund no ability to obtain assistance for a faulty overpriced item that looks like something you can buy for a 4th grader. For the price, this is insane. Definitely DO NOT purchase. Unreliable for athletes doing HR-specific training

La marca lo dice todo, excelente equipo

I bought this along with the Descent X50i for a recent dive trip and did an extensive amount of research before going with this Brand / Model. I know Shearwater are pretty strong in the wireless market, but there were several features that Garmin offered that made me select the Garmin. I liked the idea of the Sonar technology and the increased range. Since I frequently dive with my family, I like the idea of being able to monitor their air/depth as they are just getting started with diving. One other factor that made me select Gamin over the other brands is my familiarity with Garmin. We use several of their products for running, cycling, etc. and have had consistently good experiences. Some additional notes on concerns I had: SubWave (Sonar) Noise: I read a lot about the sound that the SubWave makes. I didn’t hear anything and neither did the rest of my group. I thought maybe it was due to my age, but everyone else is in their 20’s and no one heard anything. I even had the T2 Transmitter power turned up one level from the standard to make sure I didn’t have connection issues and still didn’t hear anything. T2 Connection: I was testing the set up in a pool prior to our trip to make sure everything worked correctly and became concerned because the connection would drop and I kept losing the Air Pressure data. I came close to returning the unit thinking it was a defect, but luckily decided to call Garmin Support first. They were VERY helpful and explained that the unit uses Bluetooth above water and Sonar under water. When you initially enter the water, the unit will switch over to Sonar mode but it waits until you’re around 10 feet under. The pool I was using to test was only 8 feet deep so it never made the switch and would lose the Bluetooth connection within that time. I also learned that the T2 Transmitter has it's own depth gauge which drives the switch-over not the depth on the computer. Garmin assured me that it would be fine once I was in deeper water and it was. Everything worked perfectly. My last concern was that I’d lose the connection again when I was ascending and at a safety stop, but Garmin said that once it’s in Sonar mode it should remain there until I surface. They were right. I did 4 safety stops at depths from 20-12 feet and never lost connection. Overall I’m extremely happy with the T2 Transmitter. It held connection throughout the entire day, never dropping the signal. I’m looking forward to others in my group getting one so we can monitor each other’s air and depth, but that will require an additional investment.
