Scrubber times

OK, a follow up. With the huge difference I'm seeing between the axial and radial why don't you all dive a radial scrubber?

The Meg came with an axial as standard. At the time I bought mine, ISC had not developed a radial - they have only recently released one. For me, at least, a more interesting question is why all the manufacturers fit axial as standard when radial technology has a long history with well-understood results.

I do plan to buy a radial, but I am not making dives at the moment of over 4 hours duration, so there is less need for a radial. The ISC radial takes more scrubber material, but it also has better use time per kilo of scrubber. Even so, I would need to get huge use out of it to cover the $1,000 cost through per kilo savings. If I were a caver, it would have higher priority for me to switch.

Four hours in the water at any one time would most likely be longer than I need or want, that's a long time. But I'm thinking you could load up a radial and do a couple 2 or 2-1/2 hour dives per day x 2 day weekend of diving.

The extra $1000 is an issue, I wonder how much the upgrade is if you order a radial vs an axial with the unit.

I've got a lot to learn...even before I buy a eCCR.

I dive 2 or 3 days a week, so it's nice to only have to reload the scrubber every other week or so, and it provides that much more cushion should something go wrong in the overhead.

If you know someone with machine tools/skills, you can make your own... Take a look here... http://www.rebreatherworld.com/megal...-scrubber.html

Check out the Hammerhead. It comes with a radial scrubber as standard equipment!

I have an axial and radial. Use the radial exclusively. I think it would go for 8-10 hrs if packed neatly. I have heard 11hrs as well.............:-)

I remember reading somewhere about being approx $600 more if you decide to go with the radial instead of the axial.

Some of my buddies don't get out as much as I do..., sometimes racking up 8-10 hours of bottom time might take a month or more, and they don't want to leave a packed scrubber dormant for so long and still consider it good to go...

For the active or traveling diver a radial is definately the way to go.

Hi all,

I dive my axial anything between 3 to 5h in, kind of cold water, water temp can be anything between close to 0 to 20 degree here in cold Scandinavia. I have kept the scrubber time same when diving in warmer water abroad as well. Always changing sorb if extra long or deep one ahead...

I just received my radial from ISC last thursday so looking forward to get some hours on it, actually starting tomorrow.

Mike:

You do so much sidemounting that you have to be looking to sidemount your CCR too? No use getting a unit that won't support the type of stuff you like doing. Suggest when you get your unit you start your training sidemounting, if you can find an instruction for such. No use learning skills that aren't relevant to the type of diving you do. Also, my advice is to adapt the unit to your gear, and not the other way around if you do go sidemounting.

BTW: Just received a MEG radial today and holding it next to my HH radial they both look pretty awesome. Looks like both offer good burn times.

Knowing where you go, and the nasty little restrictions you like to squeeze thru (you really need some time with a good mental health professional, you know), you have little choice but to go radial for the extra problem-solution time it can can give you. You probably need a Rebreather unit with min canister size and max sidemount capabilities, as well. The MEG might be one good unit to go with, as it is so flexible and will take the type of physical abuse you will put it thru. You might look thru the Rebreather World sidemounting threads to see what others have done in this regard.

Say Hi to Cathy, Fred and the gang.
