Hi all. After 14yrs of diving, Ive finally gotten a proper housing for my Nikon D300. Ive tested my rig and everything seems to work well with the base set up and Im trying to prepare for a trip to Guadalupe island in Oct. I live in Indy so Ikelite is a 15min drive and Ive had them go through my strobe and housing to check everything out for a clean bill of health. My issue Im sorting out is with the strobe arms. It seems no matter how tight I try to get the knobs, they still dont stay put. The ball joint set up keeps allowing things to move and drop down. Is this just because Im on land and its too much, is it a bad set up or just classic user error? Any suggestions or tricks would be greatly appreciated.
