Hello, I have several questions about the battery in my React Pro Dive Computer. The first issue is that I need the O-ring in a short ammount of time and none of my local dive shops have one. Is it possible to order the battery replacement kit directly from Genesis? Also I have attempted to look into the battery compartment myself because I think that the problem might be with the original battery. My computer was purchased a year ago new from my LDS and I have about 10 dives on it. The manual said it should be good for 150 dives. Any way after I unlock and remove the battery hatch what is next? I am not sure what part the battery hatch is and how to remove it. Any advise would be greatly appreciated!
