Standard in technical diving; personally trusted on 100m+ dives both OC and CC, also good for recreational diving. Great screen, ergonomics, connectivity, ability to configure - esp gradient factors, battery cover improved in the next model (risk of flooding)

This dive computer should get 10 stars. It is the perfect dive computer that is simple to use, yet you can use nitrox and even mixed gasses.
The display is big and readable at depth. The straps are elastic and adjustable under water. It can use many types of batteries including standard AA.
You can replace the battery using a car key or coin in less than a minute. Who could want anything more than this!

The best!!

Been tech diving for some time and have been an avid VR CCR/OC computer user! I have found that my aging eyes cannot focus on the VR screen any longer. I had spent about a year looking at the Shearwater and I have made the change. I have purchased two thus far, but have two more to go. As much as I will miss my fish hunter game on the VR for long deco obligations, I love the Shearwater that much more! Now cheap paperback books for deco and a computer I can Clearly read! Life is good- Thank You Shearwater!!!!!

Easy to use, good size display and the associated software works well. Post dive info easy to download and displays the necessary info such as ppO2, temp, depth, nitrogen etc.
The whole case is a little clunky and has that 'Canada Built' look to it but it is solid.
