Shearwater Perdix 2

Honestly, this is such a good product that I do not see what feature could be added to a new product that would cause me to replace it. The Perdix 3 is now available with a nice OLED screen. I love that it takes an AA battery, I do not see rechargeable as much of a selling point, you can always find an AA battery, they last ages too, particularly if you use a lithium one or a SAFT. I have used my current one for 100's of dives and it has never let me down, I know that Shearwater will back me up with world class support should it encounter a problem.
