Review on Mares Quad Dive Computer TRANSMITTER by Derrick Milkie

I have a Quad Air and I don't like it that much. The backlight is dim, difficult to see in dark water. All indicators have the same color and you have to remember their position. The user manual is digital only and contains complex diagrams. Finally, and most annoyingly, the PSI readings don't always work after the system is pressurized. It reads a depth of 4ft but I need to know what it reads on the surface right before diving. I can read it by closing the reservoir valve and releasing the pressure and then pumping it up, but it will flash if not submerged immediately. The Divers Diary app is garbage. I suggest another computer, be it Shearwater Perdix or Oceanic. I take care of the mares until I save enough to buy something else.
