Comments about Genesis "React Pro" Dive Computer Module:

A couple of things to consider before you buy this. I have only used this DC for 12 dives so far, but my wife also has one with the same number of dives. For the typical recreational diver, this is good computer. If you are considering the less expensive model with only one button, you can register on Genesis' web site and download the manuals for both computers and compare features. The main feature that I was looking for was PC download so the Genesis ResourcePro model was not an option. If I had to point out the bad features of this DC, it would be that part of the display (symbols printed on the white ring) are partially hidden by the black rim, buttons, and protective plastic shield. That means that you will not get a clear picture of the N2 loading and the ascent rate when you glance at it. And, if you ever should enter a decompression mode, you will have a hard time seeing the decompression stop depth. That said... after you get used to viewing the display under water, you learn the "position" of the above items. The DC also comes with audio alarms for violations and notices. For example, a single beep will sound when you reach the safety stop depth; however, the sound is so weak that you will not hear this beep. It is faint even if you hold up the DC to your ear.

With all the negatives above, here are the positives. The majority of setting, you set up well in advance of your dive. If set correctly, you will not have to change them again. The only thing that I set before each dive was the Nx %, which is one of the first menus you reach.

Underwater, the main display that tells you current depth and how much bottom time you have available is clearly displayed (calculated based on N2 loading or O2 saturation). From the main screen, you need to push a button to reach the other screens (such as max depth, temperature, O2 info, etc.). It is simple enough but you need to study the manual to remember what all the information means.

If you are considering buying the cable for PC download: Note that a lot of web-posts on the internet suggest there are problems with the communication between PC and DC. I had the same problems and was ready to give up and send the cable back until I figured out to select that you have a "REACTPRO(WHITE)." The other option ("REACTPRO") made more sense to me but I was wrong...I presume that the reference to "WHITE" has to do with the white ring around the display. Once this was done it was easy to download the information to the computer. The software could be better designed but it is adequate. I still like to keep my paper logs handy. If you do not have the cable, you can still access the logs on the DC but only the vital information.

All-in-all, this is a good computer for the average diver that do not plan to be a technical diver doing regular decompression dives.

Great dive computer but have a hard time getting the connections on the dive computer to work to download information.

My first computer. Used it for a week of Nitrox diving in Bonaire. I had to change one factory default setting and had no problem following the manual. Easy to read, understand and operate after spending about an hour with the instruction manual and the unit. Highly recommended as a first computer. Fits great into the separately sold wrist strap.
