Shearwater Predator Computer

I bought a Shearwater multi-gas computer to interface with my KISS Classic rebreather. However on several occasions I have dived it using SCUBA. When I compare it to previous multi-gas computers I have owned I am amazed. Switching gases above or underwater is the easiest I have experienced. All functions are controlled by two touch buttons. These are reliable and can’t jam. While there are a lot of menu functions, there are very few you need on each dive. The process is easy as the menu is scrolled by one button and is selected by using the other button. It has big graphics and is easy to read under water. It is back lit and that brightness can be controlled. I was diving deep, using trimix and doing two gas changes and knew instantly which gas was which. The battery is user replaceable after 100 hours.
The switch from OC to CC is really easy. It monitors the CCR oxygen sensors by cable, or it will calculate deco using a set PO2. Any data that appears incorrect to the computer will result in that data being highlighted in bright red. That is very easy to read.

Any decompression obligation is clear showing the stops and time required.

This is a great tool for safe diving. If you are a little older or a wee bit unfit, you can set a conservative factor that will allow for that. This computer is a must for deeper, longer SCUBA or CCR dives.
