But does yours work jacks doesent........:D
So is he just wearing it as a bit of (bulky) jewellery?
Why are they standing in a dark room with scuba gear on?
Of course I remember horse collars... Joyce wouldn't let me forget :)
BTW next time you see Jack, give him a refresher on mask clearing ;) but good to see he hasn't totally wimped out and started wearing gloves like the rest of you namby pamby new age divers.
Why are they standing in a dark room with scuba gear on?
The viz was 10m+
All in all a very good dives
Soon be on the local divesites ;)

I flogged one of these quite recently -- cost a whopping £3 on E-Bay, flogged it for £40 :)
Horrible things!!! Feels like you're being strangled!!!
How many of u guys started off with an ABLJ or for the really old guys an SLJ and do u have photos u could post?

Started off with the Beaufort MK 4 SLJ, then added a hammerhead bottle and exhaust. I think I've still got a few Fenzy Mk3 and 4's in the shed.
Some things u just hang on to, dont know why cos i'v got a big box of diving junk that I'l never use, but I keep It.....
Found this on the net today
Fish live on the oxygen dissolved in water and if the water doesn't contain oxygen the fish will die. That is the whole secret of keeping goldfish healthy in a bowl at home. A fish's gills contain membranes through which the oxygen in the water is absorbed and carbon dioxide given off. The simple answer to turning man into a fish is to give him such a membrane. In fact such a membrane has been invented. But at the moment it is simpler to use ordinary diving equipment. Hamsters have lived underwater for two weeks without trouble using this membrane.
Bit extreme just get a YBOD :D

US Navy tried artificial gills years ago. They managed to get enough O2 out the water to keep someone alive as long as they stayed in bed. It couldn't generate enough O2 to support someone that was moving.
i read about this a while back, some more reading with diagrams can be found here.
looks to be the most advanced to date.

I doubt it. Wearing a centrifuge on your back in a weightless environment? Doesn't sound like a good idea. You'd also have to pump a huge amount of water through the system to get enough useful air, I can't imagine for a diver bimbling along that it it is realistic. Apart from anything else the power consumption would be massive.

Who would have thought we would be diving with electronics, oxygen sensors and 3l cylinders to 200 meters...;)
