Hi everyone I am trying to be very pragmatic (read lazy) and figure out how muxh of float arm bouyancy I need to get my kit neutral, or close to neutral in sea water. I have Nikon D850 in S&S housing with 45 VF and 230 glass Zen domeport as well as 2 Inon z330s. Mostly fisheye setup (8-15) but occasionally 16-35 and then some extensions as well. Sometines I use smaller dome ports as well. I already have a pair of Nauticam carbon floating arms and need more. But how much more exactly? Maybe somebody has similar setup and did all homework (how much grams of bouyancy, measure weight of setup in water etc) and I can just copy/paste :-) Thanks, Marko
I've been thinking for ages about trying to get my system slightly more neutral for macro. With the 2x Retras I have just bought I reckon it's about 600gms negatively buoyant. That is with 2x 5" arms and 2x 8" arms fitted with a total of 8x Jumbo Stix floats which give about 1400 gms of positive buoyancy. I'm wondering about switching it from 2x 5" and 2x 8" arms to 4x 8" which would allow me to add 2x Stix Jumbos - an extra 360gms of buoyancy. Not ideal though. A bit more would be better but I'm not sure where I can put additional Stix. I don't want to use a collar. Hmmmm
