Review on Mares Quad Dive Computer TRANSMITTER by Jesse Francilme

This unit is quick to set up. So if you're good with computers, you'll be ready to dive in minutes. Easy-to-read display with large characters where it matters. You have to buy a separate device to download your profiles, but that's pretty inexpensive. There is a slight delay in updating the pressure changes but after 50 dives with this unit I don't see much of a problem unless you dive deep and with low air level. The only reason for 4 stars instead of 5 is that the markings rub off the face very easily. Had I known this beforehand, I would have enameled them for better protection. Aside from this great device that costs hundreds less than others that work about the same.
