ewa-marine video lead weights BV2
The video leads can either be inserted in the lead-belt included in some housings or strapped to the lead-belts fitted under some units. Please do not hang lead to housings that are not in the water. This will cause unnecessary extra wear to the housing and decrease its life expectancy. Clip the weights on as the housings reach water level.
Both weights are covered in a special latex to ensure that the can not leave any marks on or scratch your camera.
Please note, that the flexible housing behaves just like the organs of a diver with regards to water pressure. As stated by the law of physics of Boyle-Mariotte (pressure x volume = constant) the volume of air in the housing (just as that in the lungs, diving jacket and the air inclusions in the diving suit) decreases as it descends. In other words, a housing that is positively buoyant on the surface will be neutral at a certain depth and thereafter even show a tendency to sink. This point can be "adjusted" by adding weights to the housing, the amount of air included in the housing and some practice...
These lead weights are also suitable for use with the U-A and U-B autofocus SLR housing series.
Ideal also for almost all video housings.
