Genesis ReAct Vs. ReAct Pro

Hi All

Can anyone tell me what the difference is between the Genesis React and the React Pro? And if you have either, what do you think of it

Thanks

React Pro-water activation option,safety stop count-down timer, logs 50 dives, uses a 2450 battery (cheaper adn easy to find ) .

React- no water activation , logs 10 dives(if you don't use the PC download) , no safety stop count down timer, uses a older 3.6 volt battery (1/2 the size of an AA)

other than that it has the same features, I have both , great little computer. I mite have missed a few but you can down load the manuels on http://www.genesisscuba.com/support.html
