Default COmputers and Bottom Time?

I have had a Genesis React Pro computer since I started diving a few years ago and it seems like I am always the first one up and sometimes by several minutes. I dive nitrox and generally have the same mix as everyone else.


Does anyone know what brand of computers to look for to allow more bottom time? I am not trying to push the limits or anything but maximize bottom time if possible.

Perhaps something that supports multiple algorithms. Some of Aeris' watches do that (not a fan of Aeris, just know that my T3 does).
Research is the ticket. General comments on the web say that watch is not as conservative as others (such as many Suunto's)
Another route is an air integrated type that measures SAC and in time becomes very good predicting your bottom time based on your actually breathing..

OP, I have the same exact computer and am in the same position as you. It seems like on AIR the computer was pretty good and in line with the other guys I dive with (they are using Mares comps. Well, we have all switched to Nitrox and now my computer always gives me less bottom time than the other 2-3 computers. Needless to say I will be selling my computer soon and going with something different...

Thanks for the advice. I did research a little, but i was new to diving at the time. I think I will try to find a model I like and dig into it a little more. Are you saying Suunto is more conservative? I had always heard they were but I never researched them.

Yeah it seems like a great computer other than that but I believe your right. The guys I dive with have Mares as well and they always get more bottom time.

That's the general consensus by divers way more experienced than I. I use a zoop as console/bu, it hollars at me from time to time whereas my t3 doesn't. the key being differing algorithms on each and the t3 has tank transmitter and SAC, so it adjusts to my breathing, and adjusts to depth in and ongoing basis. Once again not an Aeris fan, just using what I have as examples/discussion points

All are different as said depending on the algorithms....Suunto are notoriously conservative but that's not necessarily bad.... for spearfishing only, I use a Oceanic Veo 200, it kinda liberal... for medium tech I use a Mares Matrix and I am mixing in a new Cressi Giotto to see where it fits in with the rest.... on Saturday, the Cressi was most conservative, then the mares and then the oceanic on identical profiles... The Oceanic gave me the most bottom time with as much as 8 minutes tween the Cressi & the Oceanic at end of day... for full tech, these go to gauge mode and I run my profiles on Z-planner & iDecpPro...

Don't go strictly for the most liberal computer, its only an average..make sure you factor in your variables such as health, weight, experience and other things that contribute to your diving ability and see whats best for you, if I'm spearfishing and shoot a large fish kinda deep with a little struggle then it be smart to add a minute or so at the safety stop to err to side of caution.. the computer only knows it went to depth & duration & has no concept of exertion involved... Good luck...

The Suuntos that I have owned have tried to kill me a several times. Never could get the factory to admit that either computer had a problem.

I would not use a Suunto if someone gave one to me.
