Gekko vs Vyper

I am as well thinking about either the Vyper or Gekko.

I would like someone to explain more about the gauge and simulation features. The gauge mode is as I've understood it for technical divers. I guess I won't be needing that, but still, it would be interesting to hear a little explanation about it.
The simulation features sounds interesting. How much use are they. For what kind of divers are the simulation features useful to?

Thanks!

The simulation mode allows you to walk through an entire dive as if you were actually making it. You can change the depth and all the displays will act like the would during the dive.

There is also a planning mode which allows you to ask the same "what-if" question you could with tables. For example, you can check what the NDL time will be for a particular depth or how much longer your surface interval needs to be be to get X amount of time at some depth.

The lack of a simulation mode on the Gecko appears to have an effect on the computer's planning capabilities. You can still check the NDL for various depths but you can't add time to your current surface interval to check things. Now, I don't have a Gecko and I've only read through the manual but this appears to be the case. If it's true then I think you're short changing yourself. Doing a full up simulation isn't very useful but the ability to play "what-if" games is.

And this works for planning multi-level dives as well?

And by the way, if I do a multi-level dive. Can I make a time/depth plan where the computer warns me to level up etc.

I don't think so. You would need the simulation features in the vyper for that.

I don't think so. Besides, who is in charge of the dive you or the computer?

I have a Vyper, which I love.

Its only weakness for me is the dim backlight (old age creeping on) on night dives but I got around that by diving with a small pencil style marker light on one of my front d rings. This lets me easily read any of my instruments even when not charged and doesn't leave me totally in the dark if my main lantern fails.

I really can't imagine using a dive computer without a download facility. I like to plot my dive afterwards and the option on the SuuntoDiveManager to walk through the dive is fantastic. Especially on deco dives to see what was happening to each compartment.

You should take into account the cheap interface when looking at the total cost of ownership of the Vyper. I built my interface for less than US$10.

I finally get Vyper for me. And for your question, You can set alarm in Vyper to alert you if you exceed certain depth, OR certain minutes from total dive, NOT based on how many minutes you spent at certain depth.

also max po2 alarms

yep it was just about the same size as my ciitizen dive watch.

DM said it was titanium and cost about $900. that was a year ago.

Sounds like a Stinger to me, the Mosquito is in a rubber case.

seven dives on the gekko and it is just fine.
2 dives were nitrox and it would not let me switch back to air until the no fly time passed. no problem just use 21% nitrox. night dive was no problem either, just shine your light on it.

if you dive air and want nitrox, it won't let you switch until no fly passes. so if you plan to do air followed by nitrox, use nitrox 21% for your air dives.

Everyone I know with a Vyper who dives EAN leaves it in Nitrox mode and selects 21% for air - IIRC it is even mentioned in the manual (but my brain could be addled post night shift! :06: )
