I bought this computer because I saw it used by my divemaster on safari - very good computer overall - to buy without fear

great freedive watch

Superfast shipping. The watch is great with all the functions you need for freediving and scuba diving

Good computer

Alexander

This is not my first computer and will be used exclusively in freediving mode. I can't say anything about diving conditions. Large, comfortable, the font is large enough, the strap is long, but, unfortunately, not as soft as we would like. The undoubted advantage is the depth of operation for diving in the free mode of 1 meter. This allows you to use this computer in the pool. Not many freedive computers can boast this or less depth. There are also some questions regarding the logic of the computer. It would be nice to add a protective film for the glass to the kit.

Great

My first computer. It has all the functions I need. I'm really enjoying it.
