My buddy (wife) and I carry two different ones. Her's is a 4 foot oral inflated. Mine is 6 foot and pretty large diameter.
We dive quite a bit in Cozumel and usually use hers in calm conditions lots of waves and wind we will use mine and
inflate it with the AAS. I have to agree on that practise statement you can do it on or before your SS. Oh yeah be sure
the finger spool or reel plays out the line freely.. I have seen someone yanked up by that SMB too .. Yes it was me..
Tip: Be sure the SMBs have a Over Pressure Valve
