12v dive pump (compressor)

[Frax]

hello..

i saw a picture of a air pump with a longhose and a second stage on it.
for diving down to 10meters.

but i cant find any information on the web about it. it was about 12kg and pretty small.. does any of you know anything about it??

it would be nice to have something like that aboard...
the mac is little to tight to bring all of my dive gear...
(2x12litrex232bar as main and 6 different stage bottles..)

Regards.. /fred

Hookah Air Compressors

Looks like these would draw anywhere from 50-100 amps powered by batteries through an inverter. Here's another:

12VDC Shallow Dive Systems

When I was younger, Evinrude used to sell something like this in a round, inner-tube looking float, but IIRC, it was powered by a 2-stroke motor, and the compressor had a snorkel that went up in the air to try to get away from the carbon monoxide.

I bought mine from "Brownies Third Lung" dive shop in Ft. Laud. Fl. about 20 years ago, gasoline engine driving a single stage compressor, I could use it to about 30 feet, two people to about 15 feet. They sell 2 stage compressors to go deeper. Still works fine. Bob

Here is a page for the gasoline engine diving compressor.

Surfacedive's quality 'Odyssey ESV-800' Dry Cell batteries are exceptional. They can be recharged directly from your boat's or vehicles generator in around 30 minutes*.

*Time quoted from manufactures users manual; charging current 90 Amps, 14.2volts.

Alternatively, the batteries can be trickle charged in 3 to 5 hours.

90 amps charging rate is what you can get from a decent sized automobile alternator running full out. What they call "trickle charging" is what you can get from a standard sized 50HP outboard alternator running full out.

So for your 70 minutes or so diving it will take you a good 4-5 hours running the outboard at a decent speed to recharge the batteries.

it looks like it would be good to buy an extra portable generator or 2.

2 sets of batteries or recharging back at the house or back at the slip or. . .buy the gas driven unit in the first place . . As dangerous as the first 30 feet can be, I am truly surprised these are still available to non-certified divers .

First (and last) time I ever tried it was at Cozumel in 1985...they took us down 50 feet.

It was great, until I came back home, researched and found out how close to death I had been....especially if there was a mishap.

Any problem at 50 feet with a novice ends poorly...

[Divecoz]

Most now run 25 to 30 feet of hose and all are TTBOMK Snuba of one sort or another and some with a bit of a twist here and there . . . feature this one . . .Its Popular too btw
A huge Plexiglas bowl/helmet you set over your head with straps around your chest and air pumped directly into that...bubble so to speak with a weight belt and weighted reef walkers . . Can you say don't slip and let the water in that helmet haha but what the heck you can't sue me we are in a foreign country hahahahah and that is pretty much how it works in resorts around the world . . .

As dangerous as the first 30 feet can be, I am truly surprised these are still available to non-certified divers .

I was under the impression that the original question was asked by a knowledeable, if not certified diver. I second the notion that anyone not SCUBA trained should not be using this equipment either.

Interesting that a reputable dive shop won't even fill your tanks if you're not certified, yet apparently they'll sell one of these to anyone with the money.

I think they are pretty cool... One day I'll buy a setup... But, I think I'll carry a spare air bottle, as insurance...

Yes, I'm certified... In more ways than one...

[Divecoz]

Poster implied he is a certified diver . You do need your card to get your tanks filled and you can buy these mail order without a cert of any kind . .
DLT at 30 feet max and for a "Competent scuba diver" to free accent should . . . be no problem just don't panic and blow the whole way up , but the time you change over to the pony tank you could be safely at the surface. . IMHO

[DLT]

You can buy any and all gear mail order without a C-card... I did... I was the only guy in my class with a full set of his own gear...

Although, I didn't try to get a tank filled... Come to think of it, I have been 'carded' everytime I have tried...

[Divecoz]

Nor needed to buy from mail order but I have always read somewhere in the Cat's /dream books that you would be asked for your cert # or so I thought .. Now that is for Regs and tanks only . In The Beginning they or some maybe most wanted to see your Nitrox cert to sell you a Nitrox Computer but I am not sure that was industry wide ..
