Mares Puck Does Everything Simply & Reliably

My first dive computer was Mares Puck - perfect instrument not only for entry level, but also for recreational diving, as it equipped with functions that cover variety of diving conditions.

Another good thing about it - diver replaceable battery option. This is very useful feature, especially, if we need to replace battery on the boat!

Positive feedback from users includes following:

  • easy to follow directions to set up and use
  • large screen and super easy scroll-through menu
  • price is extremely competitive with similar and even more advanced dive computers
