The Maritime Kit was tested by Santa Barbara County Fire Air Support Unit Ocean Rescue Swimmers and SBCFD Surf Rescue PWC Operators in the following capacity. A training was set up involving rescue swimmers jumping out of a helicopter hovering 20 feet over the ocean. A second rescue swimmer, would then jump out after the first swimmer and communicate to the helicopter crew chief using the OSK Kit that he was going to rescue the first jumper by attaching a cable to the both of them in order to be hoisted back into the helicopter. All the while, the Huey helicopter was hovering 20-30 feet above the swimmers. This continued for 3 more times while using the OSK kit.  The OSK kit was then to be handed over to the PWC operator for testing on the watercraft. Speeds of 20-30 mph were hit while transmitting using the PTT. Radio range was tested as well as clarity of communications at distances of 1-2 miles.  Initially after the jump, for helicopter swimmers, communications were muffled, but a squeeze to the (microphone) wind sock expelled water allowing for clearer communications. We didn’t get a chance to test communications without the windsock, or at speed without the windsock, or with the earcup attached to a helmet instead of on a mesh headpiece. All in all, the audio and clarity was excellent. The biggest limitation was not having the ease of being able to change communication channels on the radio. However, we are aware this does not lessen the quality of the product or its performance.  I am extremely pleased with the performance and ease of use of your product.
