Cuff dump valve
I just stuck a cuff dump valve at the top - trainees fire it off...reel it in and the valve dumps off and down it comes for the next one - easy peasy, lemon squeasy :-)

The milk bottle idea is a good idea, as it allows you to do repeated launches and then haul it back down again. The downside is that you can balls up the deployment and only get a smidgen of air in and still get it up. However i guess you can try with a real SMB for the last deployment.

And another Handy Hint: when going for the final DSMB launch bit, take a few with you. Send up the first one and assuming it all went smoothly and didn't propel you to the surface, send another couple up the line on a double ender for the practice. You'll end up with a load of inflated blobs at the surface all on the same line. Careful though as Mark Davies will probably send a cylinder of 50% down

Doesn't the air just all piss out of it as you squirt it in? Not wanting to state the bleeding obvious or anything. Unless it's nt at the top.... hmmmmmm.

Thats what i would expect bearing in mind with a cuff dump you lift your arm and it dumps air!

no problem
It always leaves enough air in to float nicely - try it, it works a treat.. like your suit, holding your arm up doesn't dump till you have suit squeeze..it just equalises nicely
