Comes with a unique holder and battery pack system that makes it easy to carry and manage 50 feet of cable. The portable FISHPHONE pack system can power your FISHPHONE for six hours between charging. The camera used in the FISPHONE system is a Sony Color/ B&W camera that automatically shifts from color to black and white when light conditions are limited to increase contrast. There is little doubt underwater camera technology is getting lighter and more portable and with the FISHPHONE, Vexilar will be changing the way people look at underwater camera systems.
