If you are a scuba diver looking for a dive computer that is simply easy to use, then continue reading because the new Mares Puck Dive Computer Series was design with that purpose in mind.
The Puck Sports a single button to scroll through menu option, which alleviates the feeling that if you hit the wrong button you might screw something up.
It also has larger digits that makes it very easy to read, as well as back-light on demand for low visibility conditions or night dives.
It utilizes a conservative algorithm for an even larger margin of safety, this is perfect for entry level divers or divers how are very conservative. However, there are two “personal correction” settings to make the computer more liberal.

Great little computer with a lot to it and simple one-button scroll through. The one drawback is that there doesn’t appear to be a way to track your surface interval in the ‘logbook’ menu without calculating it yourself from dive times and times entered into the water.

This was my first computer and I have used it on about 25 dives, including my advanced open water training. My gear is a mixed bag of several brands and I did not initially have a computer in my gauge package, so this wrist mounted pc is great.
As I always say in reviews read, read, read and try to run through the functions on dry land.
It has settings for audible alarms which sometimes bug other divers LOL and increased safety factors for the algorithim.
Once I learned how to use it, I love it.
I wish the product had the digital instruction now advertised when I was learning to use.
Guess having an experienced dive buddy to run some questions through would have been helpful, but ultimately this was easy!
