In both situations it's far better to not get mauled/not get caught than to have some miracle tool to get you out of a really really really bad situation that you could have avoided.

I've been using the Mark IV for tree skiing, it adds about 200lbs and makes it nearly impossible to turn but I hardly feel the impact of tree branches as I pinball down the hill. I just find a steep line and have one of my 'friends' kick me in the back of the head to get my momentum going downhill... good times, good times.

I think old troy must have done some damage to the grey matter with those earlier suits  .  I hope he's ok.

Not much to do for the impact and trauma, but it seems we could use scrubber technology to get rid of the CO2; the WWII technology should be off the secret list by now.

I dive a rebreather and use CO2 scrubber technology most weekends in the summer. Its not rocket science nor secret. Thousands of divers do it every day

mmmm I wonder if a cupfull of scrubber in a bag around the neck wouldnt actually help!. Need to do some sums

About 1/2 litre would do for 1 hours CO2 absorb, but breath would need to actually be passed through it

Hey a snorkel, packed with Sofnolime would cost about $2 a refill, last a week if not used. Breath in through nose and out through snorkel, 1 hours CO2 absorbtion

On second thoughs a £4 snorkel, breath in through nose, out through mouth and you have an avalung for pennies, Get a valved one and reverse the valve and you can breathe in from in front and out behind head, poor mans avalung and great for deep pow

Integrate the scrubber into a helmet, and you don't have to worry about making sure the snorkel or aqualung mouth piece is accessible.

Isn't that what an Avalung is all about?  I understand you can breath in through the mouth and when you exhale, it travels via tube away from the face.  So the CO2 scrub would be unnecessary.

Yeah, like they did 20 years ago with transceivers, probes and shovels.  What'll they think of next?

Not to worry JER.  BC requires work above and beyond money, it won't get too crowded for too long.

There will be good deals on even more gently used BC stuff though.

Best possiable anti avi gear?  Good reading and study on the topic, and a working brain.

Well, my skill with rebreathers is in the controller and O2 injection software anjd writing simulators for them. But I dive with the guys who designed the Inspiration and KISS rebreathers so I will talk to them about it. What will be the limiting factor will be the amount of Sofnolime folks are willing to carry (head mount or backpack), will folks tolerate large diameter tubing running from helmet to container (suspect not)/ How long it would have to work under snow (suspect 1 hour) and how long it would be worn in active mode during a day. good news is i suspect it would be mechanical, not electric

For those interested in the technology of rebreather see www.divermole.co.uk
