On review using the Buoyancy Calculator spreadsheet over in Equipment -> BCs, it is evident that with a steel HP 100 and a wetsuit a complete loss of the wing will result in being about 12# negative even after ditching the weights. This condition occurs at the beginning of the dive, with a full tank, when the wetsuit is compressed at depth.
So, how to provide backup lift?
I am looking at the OMS SMB which provides about 50# of lift OMS Lift Bags & Surface Marker Buoys http://www.OMSdive.com. This seems like a reasonable approach in that it provides plenty of lift and the desirable SMB function.
Has anyone actually tried to get off the bottom using only an SMB? Is the web strap at the base of the OMS SMB actually capable of staying attached (not just tearing out) while providing the full lift capability?
Are there other methods (not including redundant bladders) that I should consider?
Thanks!
