Thanks, I will consider them,... at fisrt sight the Sony HC9 camcorder is no longer available..
A friend let my try a JVC Everio camcorder and Ike housing, with MWB control, unfortunally at 70ft the manual control rods were hard to control since the presure pushed in the rods, while I needed to extract them back to manage the joystick. Next sunday I will close/seal the housing with the rods extended out, to provide a small pressure compensation.
