I used to have a drysuit that had a "vanity zip" (a zip across the crotch area to pee out of). I had about 50-60 dives on the suit and was on a diving weekend when I was sitting on a slipway and a group of divers came in. I had to spend a few hours in the suit so I had opened the vanity zip to...

^^ cheers for that, you brought up some stuff i hadn't thought off before, mainly the stuff abut keeping the gear in the warm for as long as possible before taking it out into the cold to kit it up then getting in the water as fast as possible. I never really figured that icing would be a...

Annoyingly enough I had a 2nd stage reg freeze up in the boot of my car last weekend (air temp over here are sitting at about -8 Celsius). I put it on the tank and switched it on and it just constantly free flowed. I chucked the kit in the sea for 5 minutes and it all thawed out (Sea...

I carry lots of safety innovations with me when I dive such as: an SPG, so I can see how much air i have A second regulator so my buddy can breath off my tank without us having to share regulators A BCD so I can gain positive buoyancy in an emergency without having to drop weights There was...

Aye if you can be considered to be at work you would have to follow the HSE regulations. Ive always found that the whole thing of whether HSE regulations apply to any particular dive tend to be somewhat of a grey area. Ive never heard of any of the dive organisations falling foul of the HSE...

The HSE regulations only apply if a diver is "at work". This would normally be interpreted as diving for personal gain. These regulations also apply to self employed divers so if I accepted money from someone for, for instance, inspecting a mooring I would count as a self employed diver and be...

1. 20m (66ft). Max 30m (100 feet) 2. 1/2 litre "suicide bottle" built into horse collar, charged to 200 bar (2900psi) giving 100 litres(3.5 cubic feet) of air. 3. unsure of what my actual SAC is, I use 1 cubic foot a minute for calculations. 4. never had to use it in anger, ascended on it from...

I find it slightly scary to think that I could end up buddied with and relying on someone trained like that. If someone wanted to go get trained by someone who wasn't qualified and go off diving that's their choice, I've met people like that and I take them as they come (Ive met people who never...

Man a high def mask. I still remember when all you could get was an analog mask then they brought in digital masks that way improved the vis. I wonder how long it will be till someone brings in a 3D mask that allows us to see the ocean in full 3D like in the cinema? Isn't technology amazing...

The fact that you say you where breathing very shallowly and started getting light headed/dizzy would make me think carbon dioxide poisoning if your not breathing properly and it builds up though I don't know enough about carbon dioxide poisoning to be sure. If you had a cold it could maybe have...

Yeah aye sorry mised that bit out. Id get the air source before anything else since its the most important thing. If your still breathing its not an emergency as they say! Yeah myself and the people i train with are all recreational divers too, max depth 30 meters and no stops e.t.c. You...

Dont worry im not an instructor either :D I take trainees in but under the supervision of an instructor and I take newer members of my club who are already qualified in order to keep them sharp and develop their skills. Im not formally qualified in any way to teach :D I think clearing the mask...

Yeah if i lost my mask and reg on a dive i would put my reg in first. What the drill does do though is increase their proficiency at clearing their mask, they cant just furiously blow air through their mask till it clears, they have to seriously consider what they are doing and not waste air...

you may be surprised, if you really practice so you can clear your mask without a single bubble going past the lip of the mask and no water coming back in you would be amazed at how little air you need. My personal record is 7 clears using one of these masks: Hardly an easy mask to clear...

Well I do fin pivot to start because you would be amazed at how many people I have taken in who are unable to attain neutral buoyancy. Doing this first makes sure that they are properly buoyant for doing the outher skills. The idea of hovering with your legs crossed and arms holding the fins...

The standard set of skills I run through on every pool session are: Fin pivot Remove regulator and replace remove mask and replace Perform out of air drill as donor and recipient Perform rescue Perform forwards and backwards roll Remove BCD and refit Once I have done all of those I...

I have the brittanic episodes to and your right they are triples, i must be going blind :blinking: I took a couple of screen-shots to show the ball things i was talking about: And another one showing the manifold better: I must say i love how he keeps his hat on. I wonder what the "scuba...

Thats one of the most awesome things i have ever seen! I remember watching a documentary of Cousteau diving the Britannic and the divers all had huge big double cylinders of heliox on their back. They seemed to have these big white football sized balls attached to the top of their tanks. I...

The RNPL tables without a doubt. The ones i use used to be used by hard hat divers in the big old brass helmets when they where commonplace so they are quite old but by god they are simple and make life incredibly easy. Its incredibly useful being able to look at your watch and depth gauge and...

id guess the healthways in the centre? So...I take it your clearly an apex man? :D
