Which Rebreather ??

colinicky · 18th December 2007, 19:15

Ok this is on behalf of a friend who is thinking of getting a ccr .
He does dives to 60m maximum & hasn't decided on eccr or mccr although he is leaning towards eccr BUT I only have limited experience & only with my Vision .
This is not a question of which ccr should he buy etc but more which one will survive a backward roll entry the unreasonable height off of a hard boat !
He has very limited strength/movement of his legs on dry land but enough for finning underwater hence the need to roll in .

So which would survive this constant type of entry ?

About all I can suggest is something without external counterlungs, so they don't sustain sudden compression when he hits the water. Might blow a seal. No pun intended.

The travel rEvo springs to mind as its so lite and has the gag to stop the loop being pulled out of his mouth on entry. Especially if he can afford the Titanium box. Can he hang on for the Shearwater Head in the Spring?

Mind you if the units going to take a lot of bashing around maybe MCCR is a better option?

If he wants a play on MCCR M8 you know where i live

Appreciate that Mark the problem is getting him in & out of a lake ! The hieght we're talking is like sitting on the rail of channel diver & doing a back roll so it is a fair way IMHO.

Colin,
If worry about getting him in and out of a lake is stopping him from trying Marks KISS then surely we can get enough people at Wraysbury to help him? I'm not the worlds smallest person and I'd be happy to help.

If diving in a lake with presumably little or no current, why not put the Rebreather on in the water? And any stages? It sounds like a safer option all round.

If you're still looking at units to roll from a height, I'd consider the robustness of any electronic bits, where the counterlungs are positioned and how they're protected and how the breathing hoses attach.

FWIW, I'd have no qualms about a backward roll entry with my Boris and have done it a few times, but given the weight of the unit out of the water it's probably not what you're looking for.

Have "hit" the water at various angles on the KISS without issue (as long as you hang on to the DSV!) There is a certain amount of CL compression on impact but its managable.

Both CK and SK have been off the high platform at Gildenburgh without issue.
My buddies have Inspiration Visions and don't seem to have any issues with backward rolls, the CL's are following them into the water on a backward roll afterall!

The suggestion of a rEvo seems wise, if he has limited strength then refilling a large scrubber can be hard work, the small rEvo scrubbers might be more of a table top operation to refill perhaps?

colinicky · 19th December 2007, 15:22

Wrasbury is probably a better option as they have the concrete ramp for access .

Strength is not a problem other than his legs ,after all he uses his upper body for the wheelchair & can haul himself onto a hardboat like Dive125 at Eastbourne were you "climb" over the side & then lifts his wheelchair on afterwards on his own .the only help he really needs is the skipper moves his twins from the bench to the siderail for him to put on, so scrubber fills etc are not an issue .
Am going to have a long chat with him after New Year & may then ask for some help with him trying various ccr's .
thanks all

Hi Colin,
Stoney has a couple of entry exit options,that may be worth considering,a fairly good ramp witth low walls, & the steps with the platform at about3 feet.
Give me a shout wherever you decide to go & I,ll see if I can make it ,he can have a go on my meg.
Cheers.

I dive the Pelagian and believe it may fit the bill. It is an MCCR with no complex electronics to get bashed. It is very light compaired to other CCR's and the counter-lungs are on the chest so they do not get compressed on impact. It is also relatively cheap at about GBP3k. Check it out at: Pelagian Diver Controlled Closed Circuit Rebreather.

I am very happy with my unit and have done back-roll entries off high sided hard boats without any issues.

Regards,

Carl
