Dunno what you were doing with it, then....

I use 2 x 2kg mounted on the unit, in the sea, with an O'three crushed neoprene drysuit and winter underwear!

When I took it up to the pool for someone to try, no weight at all in a pool suit.

A common issue for inexperienced rebreather divers is to dive with the loop too full - did you get your divers to run the loop volume down?

correct: I could not dive at minimum lung volume: had to trim with the lung because no inflator connected:
this means normally you don't need to put weight near the top of the boris do dive it horisontally?? (he is not 'top-light'??)

Paul, yes, it is a bit light at the top. I've moved the unit lower down my back on a steel OMS backplate, and fit the 2x2kg weights on the fixing straps at the top, it now trims out fine.
