I’m struggling with the weight of a Patima G9 housing. The weight underwater with one Inon strobe and a Inon UWL-100 lens is noticeable, 1 kg (2 lbs) or more. Do you know what these floats are, and if they would help, i.e. are they non-compressible (from the newest issue of Uwpmag):

Alternatively, or in addition, could this work (Stix float belt):
