Re: Over-under shooting with a big dome

If it weighs 30 lbs and neutral in water, it has a volume of about 1/2 cu ft. To hold neutral half in-half out, 1/4 cu ft. would be submerged; and 1/4 cu ft. of near weightless material would have to be placed underneath. 1/4 cu ft could be made up with a piece of foam or inflatable bag, 4x9x12 in. Would probably be best to make the 4 in dimension its depth and the 12 in. dimension parallel to the long axis of the housing.

To make it stable in water, you could eliminate the lights and tray, and attach a thin plastic platform to the bottom of the housing using the tapped holes where the tray normally fits. Then bungee the foam piece or bag underneath it.
