Nauticam has introduced a Cooling Fan System for the NA-R5II housing designed for the Canon EOS R5 Mark II camera. This new feature helps prevent the camera from overheating, which is crucial when recording videos underwater. The cooling system runs on two rechargeable AA batteries and has an easy-to-use button to activate it. With this innovation, underwater videographers can shoot longer without worrying about their camera shutting down due to heat issues. The Cooling Fan System is currently priced at $633.
