DSMB Recovery

[Phil Ennis]

<font color='#810541'>While chatting with Dave Willow and Chris B at the weekend the subject of recovering your DSMB from the surface and re-stowing it was discussed. It sounds like a cool trick which I must try, but why would you need to do it? Or is it just a buoyancy skill? &nbsp;

How's that work then?

Sounds like a really useful trick for using when practising DSMB deployment, &nbsp;deploy.. recover.. deploy.. recover etc.

<font color='#810541'>Daz, you set it off then bring it back down from the surface empty it and restow it. Cool or what, can't wait to give it a go.

OK.. &nbsp;I read your reply 5 times and I am still none the wiser... &nbsp;How do you pull it back down without winding yourself up the line.

I did try this the other week at a quarry but ended up wrapping my legs around a post and knackering myself out pulling the DSMB back down.

Is there a recommended depth to do this from and I am guessing minimal air is required - just enough to get it going.

Easier than you'd expect really, only make sure you don't make my mistake and put too much air in the bag, I also think it can only be done with a spool...

Hold a horizontal position, slightly head down and put one hand up the string and pull a length of slack... then just spool the loose bit onto the spool itself with the other hand, take another arm full of slack and repeat until the bag comes back down to you.. a slow frog kick helps to keep you in place..

<font color='#0000FF'>Sorry guys - I'm really confused here ! &nbsp;
Why would you want to learn a new technique for this - whats wrong with just slowly winding it in as you ascend then just grab it at the surface and get out ?

Or am I missing something ? &nbsp;

Cheers

I'm afraid I can't help with this one. &nbsp;We don't use SMBs in caves :-)

Seems like a pretty cool thing to do though.

Remember that the positive buoyancy of the SMB at the surface will be halved at 10m.

jj it's not a skill set as such it's just for fun, although it does come in handy for DSMB deployment practise.. launch it, retrieve it, stow it, launch it again.... As we like to be able to deploy while holding trim and position in the water column the practice helps

Sounds like a good enough reason to me...

Will definitely be giving it a try sometime and let you know how it goes, &nbsp;I think I am pretty reasonable at deploying a DSMB with a spool now but a bit of practice never hurts.
