Practical New Gear You'd Like To See?

[DaleC]

I just want a cheap reliable high output light suitable for video that won't flood. I don't know what it is about pressurizing that adds $000 to the price tag.

How about a system that allows my tank to be refilled without having to unmount and remount my reg?

Get an H-valve and only put on one reg, use the other port to refill tank.

I would like to see the GPS data for the boat or entry location with a map of the undersea floor on it. Having a buddy marker might be nice (Other than a can light) in case of separation, or in the event of a planned separation.

Each diver in a charter boat gets a small watch-style or 'hockey-puck' wrist unit that gives out a signal of something - steady, pinging, whatever. On the dive boat is a main unit that looks like a 'fish finder' and can show a 2-D graph depicting each wrist unit in terms of depth, direction & approximate distance.

Now wouldn't THAT be useful tech. in some of these missing diver scenarios?

Makes you think.

There is at least one quarry that says if you are going to go out solo you have to carry one of these transmitters so they can find your body.

For computers that already have a compass an algorithm to track your location compared to your "start point" would be fairly easy to incorporate. I suspect computer manufacturers know this but just don't think there's enough demand. If they ever do incorporate it, though, I suspect it'd carry a hefty price tag.

For the photographers, wouldn't it be possible to simply "extend" the exhaust on a 2nd stage to deal with bubbles? Would that trapped air space really be too much to deal with or would a hose cause too much restriction of head movement? Could there be some other pressure issue with it that I'm too dumb to think of right now?

Any time I see a datamask I think of how expensive it would be to have a MOF moment, or have so
someone knock it over board.

You know, with the varied 'missing diver' threads that show up in the Accidents/Incidents section of the forum, imagine a reverse take on the 'return to boat' navigation system for divers.

Actually they have this. I was at a psd conference and played with it a bit. It was cool all on sonar signals and every diver in the water became a repeater. You could have up to six divers. It reported back to what looked like a iPad that essentially had a air integrated dive computer for each diver. One page would show everyone's location and depth , another page was essentualy a dive computer with real time numbers. Depth air pressure rate of consumption rate to a preset pressure limit and how long you had been stationary. It kept all the stats for 24 hours until you were fully off gassed. Here is the catch 6 divers the system cost about 150,000. Our dept is not ordering one. But wow was it cool

I wouldn't say it is easy to do, but perhaps it is possible.

The compass would need to know what distance you covered at each bearing in order to track your position.

Liquivision claims that their new Lynx computer can track a bearing to your buddy if they have the same computer, and also back to the boat if the boat has an appropriate Liquivision transmitter dropped in the water. It is also a gas-integrated nitrox computer (not trimix).

Nope, without getting in deep, the diaphgram of the second stage and the exhaust must be about the same place, otherwise you end up with either freeflows or very hard exhale depending on the relationship of the 2. It's more complicated than that but that is the general idea. Just extending the exhaust pretty much buy you the same problem....that is why the double hose reg is a double hose, it orignially was not....and it didn't work.

Good point about the distances. If you had an "easy" distance input option then the algorithm itself would be trivial at that point. Getting the distances is what we're missing now.

I wasn't sure about the exhale pressure being significantly different or not, but that was the only downside I could think would be "obvious". I didn't realize the double hose was originally an unsuccessful single hose design. Good to learn.
