Training vs insufficient depth

[picasso]

Hi guys, we have limited possibilities to train here in Czech rep. We are very happy to dive in our 58m deep and 4 celsius degrees quarry, completely dark at the bottom. You can get used to these conditions but it should be deeper for “perfect” training :head.

Mostly we can train technique, CO2 tables, playing with mouth fill at various depths, FRC to simulate depth and some hangs to stay in depth for some time. For me it is better not to stay deeper than 30meters during hangs because body is not relaxed in such cold water and you can get squeezed when contractions start to pump.

Do you have similar experience? Any thoughts on what else you can do in such conditions?

Thanks for your feed back

58m is more than enough! Try doing some extremely heavy dives (huge weight belt), and also some very 'positive' dives (almost no weight).

You can also do repeats to 58m but you need oxygen to deco in between.

Thank you Eric. I used to repeat dives at least 2 times (without oxygen). I try playing with weights ;-).

is there an easy to remember rule regarding repeat dives?

Wear a thicker suit, or some sort of vest underneath your suit. You'll have more warmth for a hang, need more effort to go down, more to come up.

To me 58m sounds like more than enough for depth training. Maybe not enough to get comparable narcosis, N2 or CO2 narcosis. But that does not apply much to my level yet, pb 65m CWT. For me the training would revolve about relaxation, speed, equalisation, swim technique.

Thanks Cars. Good idea with some additional short wet suit . My PB in training is 93 CWT and 72 CNF so I realy can't do a max dive there. You can't get narcosis either but you can see a bugaboo down there since it is dark and some divers are bit affraid to dive there :t. The quarry is quite large so it is also difficult to find more than 50-55 depth.

Maybe you should try a 40m-45m 'double dip'

 

[efattah]

In a dark lake you can easily get bad narcosis at 58m if you dive with high CO2 and hang on the bottom for long enough. Use fluid goggles and the brain freeze will make the narcosis twice as bad.

Will Trubridge would do hangs at 50m with high CO2 and reported worse narcosis than on 110m+ dives.

Also, if you are going to do hangs at 58m, neoprene is useless. It is compressed so much at that depth that it won't offer any insulation down there. You are better off putting sheets of silicone or butyl rubber underneath your wetsuit. They have less insulation than 'full' neoprene, but at 58m they offer way more insulation since they don't compress.

 

[Kars]

Yep, Eric That's why I wear a silicone swim cap underneath my hood, to keep the head extra warm. The brain frees is something I don't like :martial

Also the skirt of your mask will make a big difference in insulation compared to just goggels. I got my sinuses and ears block completely hitting the first themocline, going from 19c to 12c.

I have tried fluid googles only 3 times so far for just simple CNF dive to the bottom. But is is rather painful in 4 C degrees . I am affraid of my sinuses too. But I try hangs and wait for some narcosis. I haven't experiences narcosis even in 93m, but it was quick dive (2:48) and temperature about 26C in Sharm .

I've been getting narced on 60m spearfishing dives

Sorry if I'm off subject here but:

@Eric, do you have any goggles in stock right now?

@Dave, what's the deepest you have shot a fish? I think Trevor Hutton has officially (i.e. documented) speared the deepest fish at +-62m.

 

[Mullins]

Just slightly over 60m. I've been deeper but didn't happen to see anything worth shooting. VWT assistance for part or all of the dive depending on conditions, so it doesn't really count. It really is very easy if you're used to CWT.

good job. You can say that everything shallover to 60 is snorkelink for you rofl.

Trevor shot that fish in 60m in constant weight, in the worst conditions humanly imaginable, including huge current, being in shark infested water with a bloody fish nearby, and with a spaghetti layer from 30-50m in the water.

However after the dive he told me he feels he can shoot a fish at 70m if the circumstances are right. Maybe this becomes a new competitive category!

 

[basilisladias]

wow! Good idea Eric! Spearfishing in deep wrecks for eg....!!!!!

Time to scrap No-limits and replace it with CWT Spearfishing... going to be pretty hard shooting a fish with fluid googles on
