OK, I just finished a week in Coz with the Descent on my left wrist and the Teric on my right. It's really hard to compare the two as they have such different features. First, the negatives and I have one for each PDC. The Teric needs charging constantly. I'm not getting 52 hours and so have been charging it nightly. On the other hand, the Descent's display looks like crap next to the Teric. Sure, I can read both but the Teric is far easier in sunlight and at depth without my glasses on. Now for the features which really affect my diving and daily life.
Descent: This is a fitness trainer watch that's added a PDC function. It's big and a bit clunky, but so am I, so I wear it all the time. The features I like
- Step Counter
- Swim/kayak/fitness tracker
- Move! nag
- Tracks my heartbeat
- During the dive
- Won't work through neoprene.
- GPS function shows the beginning and end of every dive
Teric: This is a Petrel that has been run under Bugs Bunny's shrink ray! It's amazing and intuitive. It's big, clunky and an ounce heavier than the Descent. It can be worn as a watch. but you have to keep after the charge. The features I like
- The overlaying compass
- By far the easiest in the industry
- You can still see your depth, gas and time while navigating.
- AI (Air Integration)
- Very solid connection
- Easy to access
- Easy to read
- Easy gas set-up and switching
- Very easy dive set-up
I find that during the dive, the Teric gets my attention until the Safety Stop. I can choose a 3 or 5-minute safety stop easily with the Descent, and 5 is always my choice. I haven't found where to do this on my Teric yet and it's set to 3. On the surface, the Descent gets most of my attention and has become my day to day watch.
BTW, I use both so I added that to the poll.
Both have very different features so it's very hard to choose an overall "winner".
