Have a little build up of gear to try to clear out.
Aquatica Extension 18453
Aquatica Extension 18463
Aquatica Extension 18457
Sea & Sea YS-110a x2 - well used, but one of my favorites, includes diffusers
Sea & Sea YS-110a x1 - picked it up as a backup, 1 of the 3 flash tubes doesn't fire
Sea & Sea YS-D1 - got as part of a pkg buy, don't need
Sea & Sea YS-D2 diffusers 120 x2
Sea & Sea YS-D2 diffusers 100 x2
Sea & Sea YS-110a diffuser (extra spare)
Spare Retra LSD mounting kit for ys-110a strobe
Strobes are older models but take both electrical and fiber, so (in my opinion) they are still very relevant. These ys-110a have honestly been the most reliable strobes I've shot. You won't shoot a fully lit, wide angle reefscape scene but these should suffice for anything outside of that, and possible fully stopped down snooted f/32 shots.
Will add pics on request, but send me a msg if you see something of interest and we can work out the prices.
