Ewa-Marine BS7 soft lead
The soft lead BS7 can be used in almost all photo and video cases of the company ewa-marine. It is packaged in black plastic bags and therefore cannot scratch your camera.
The soft lead BS7 weighs 0.75 kg.
Please note that the flexible housings behave in the same way as the diver’s water pressure. According to the law of Boyle-Mariotte (pressure x volume = constant) The volume of air in the housing (just like in the lungs, in the jacket and the air bubbles in the neoprene suit) decreases with increasing depth of diving. In other words, a housing that has lifted on the surface is neutral at a certain depth of immersion and then has a certain downforce. This point can be “adjusted” by means of the lead and the amount of air in the housing with some practice before the dive.
