Seeking suggestions on trying to video record an SMB blowing up as it ascends

[L13]

The difficulty will be finding multiple divers with cameras willing to do such a thing in November/December in Seattle.

Once you go dry, diving is a year round activity everywhere!

Multiple divers recording and perhaps somebody on the surface would be my recommendation. The difficulty will be finding multiple divers with cameras willing to do such a thing in November/December in Seattle.

I'm diving Saturday... the water Temps don't change much here

One possibility

We dive year round. Not a problem at all.

Good to hear

Shoot an smb that is attached to a dsmb with something rigid (kite poles?) Connect your go pro to the dsmb. You may have more luck tying the 2 buoy to a hard anchor point and cutting a line to release them at once.

The difficulty will be keeping the camera pointed at the SMB

O ne day I'll buy a dry-suit. Until then, I'm a lazy slob in Texas.

If you capture the expansion with adequate detail, that will be informative.

However, I think the rupture will be anticlimactic.

I’m not against the effort, just trying to be realistic that a burst seam probably won’t get many “ooohhs” and ”aaaaahs”.

That is why I was suggesting a rigid frame between the two. The camera could be rigged between the two with no movement allowed until BOOM

Agreed. I would like a continuous video source as the ideal solution. But that may not be practical.

I think it will just be a burb as a seam somewhere will fail resulting in a sudden exhale and then the SMB goes limp. But good teaching point for why one should not hold their breath if an ascent is possible.

Maybe it would be better if you inflate a balloon rather than a DSMB? It would probably go pop on the way up?

Not sure how doable it would be to inflate one? Maybe you could buy a DSMB one way inflator valve and glue it on the balloon?

DSMBs have OPVs, SMBs don't. I can inflate both and have attached to some sort of an anchor. I'll probably have a connection to a line to keep track of it. We will see. There's a bit of experimentation needed.

I have an AP crack bottle DSMB I'll probably never use again. Attatch it to a 5 lb weight and crack the valve. You ascend and film the DSMB as it goes past.

Add a bottom drag chute so the SMB does not pass up the DSMB.

DSMB - camera on pole for better alignment - SMB - drag chute - recovery/ascent line - bottom anchor
