Puck Pro Ultra Dive Computer - Air, Nitrox, Depth, Decompression, Temperature, Time, Dive Data

Bought this for son and wife. Probably unbeatable at this price point. It has a clear display, just the right amount of information, replaceable battery, and easy navigation. Granted, if you haven't used a computer with only one button before (like this one, or say a Cressi Leonardo, among many other examples), having one button alone can be a little confusing unless you read the manual at least once. This being said, navigation is not hard if you read through instructions. I think unbeatable value for being well under $200 across all recreational levels. It uses Buhlmann ZH-L16C algorithm with dual gradient factors and while this model allows for EAN (Nitrox) diving, as you progress in certification level you'll probably want something slightly more sophisticated, at which point this becomes a good backup computer alternative.

Great, easy to use dive computer. Syncs up perfectly with the Mares app.

Easy to use and also big enough to read. Love it!

The wrist band looks quite cheap and thin . No keeper or strap loop included, so to put the computer is a bit odd. But it looks nice for the price. We will see. If you can afford a more robust /expensive computer, go for it.

Basic dive computer. Nitrox compatible. I like the bluetooth feature for the price
