Modifications to increase maximum depth

Brainx3 · 29th December 2007, 13:36

Hi,

I'm still doing research about cams.

Niels' advice isn't all bad. While Inspirations have been dived quite deep safely, you might want to look at the CO2 detector vs. temp stick thread. While the subject are temperature sensors ("scrubber gauges") and CO2 sensors, there is some interesting info/graphs regarding scrubber performance. Worth reading and taking into consideration IMHO.

How about a modified IDA-72...Its been there.

Hi,

Thanks for the link as I think it's very valuable and it's unfortunate that we haven't seen any CO2 sensors or monitors in the market that can be used in CCR diving until now. Nevertheless, my question was about what modifications that can be made on the unit itself so it won't have any electronic failure in order to be able to reach 200 meters. You mentioned something about others who have taken the unit deep. Would you like to share more data about that? and whether you know if those guys have done any special customization to the unit before they took it deeper than 170 meters?

Best Regards. Wael

hi all,

sorry for jumping in, but couldn't resist. how about getting a meg, if you are to change a Rebreather. iknow for sure its been there and deeper...and most important, without modifications...

Thanks.

Hello,

You might want to tap Cedric Verier for input. He did an article on modifications to the Meg for deep dives and he has experience on APD equipment as well.

I haven't done dives that deep, but it seems to me that, for a single dive with that much uncertainty about your specific rebreather, why not go OC for the dive?

Or perhaps leave the Rebreather on the line at a depth it's happy with and go OC from there until you get back up? Perhaps using that format you might not need much more gas than you'd have to carry for bailout anyway.

Or bring lots of bailout and hope for the best.

Seems better than matching the wrong equipment for the dive.

What other risky activities do you involve yourself with? You might be better running the Tour de France on a tricycle.

Seriously though, the only advice you are likely to get back from APD is that the unit was not tested or designed for 200 meters, and that you shouldn't do it.

If you are hell bent (no pun intended) on going to 200 meters, use another unit that has been there before. For what you could sell your Inspo for, you could buy that Mark 15 on ebay.

Have you done many dives past 195 meters before? You want the first to be a filming expedition? I certainly wouldn't sign up for that.

Are you planning on bringing the 500 cubic feet of bailout gas or are you going alpinist? 4 hours deco for 2 minutes on the bottom does not sound like fun to me.

Aloha,
Charlie

Hi guys,

I really thank you for your suggestions, however I'm not familiar with other RBs beside the Inspo/Evo. Doing the dive on OC will take LOTS of handling issues that's why doing it on the Rebreather would be more sufficient. However, if there was a potential risk of having any failures then definitely we will go with the ROV instead.

Which rebreathers are officially rated to 200 meters??

Best Regards. Wael

Hmmm ... risk of any failures at 200m? .... Hmmm ... risk of ANY failures at 200m? ... Hmmm ... risk on ANY failures (OF A MACHINE) at 200m? ... hmmm ... hmmmm ... hmmmmmmmmmmm ... good luck on your quest.

Dude...you're kidding...right? Are you a troll or are you serious?

Quit diving. Take up croquet or something.
