yes. try this, purge your suit as you come up, and you will stay vaccum packed and as a result, have very little buoyancy from the c4. marv deepdive wrote: > Sounds reasonable to me... > > Is your weighting for neutral buoyancy at 3m with minimum psi in tanks, > minus the cannister light/stages etc? > > Still curious... > > > -----Original Message----- > From: marv [mailto:ajmarve@op*.ne*] > Sent: Thursday, 30 August 2001 2:43 p.m. > To: deepdive > Cc: TECHDIVER > Subject: Re: FW: Silent Submersion Vs Dacor > > > 12 lbs belt, 6 lb plate, pro 6 canister w/ tls350 and c4. hiland bands > w/ sea elite manifold. luxfer standard 80. > > marv > > deepdive wrote: > >> Hey marv, >> Have you been raiding the scrap dealers for lead or what? >> As that's one helluva V-weight you're talking about...let alone >> slung on a weight belt. >> How much weight do you have to carry with your twin 80's in > > drysuit > >> and ocean diving? >> Just curious... >> >> Paul Berry >> Southern Ocean Explorers >> DIR-N.Z. >> >> >> -----Original Message----- >> From: marv [mailto:ajmarve@op*.ne*] >> Sent: Wednesday, 29 August 2001 3:51 p.m. >> To: Jim Cobb >> Cc: terry michael; MHK; Michael J.
