We operate in the ocean in Southern California on Yamaha Jet Skis and we are often entering the surfline and taking waves over the bow and off the stern during aquatic rescues and emergency situations. This equipment needs to be able to withstand the harsh and salty marine environment while delivering clear communication with units on shore. Thus far in testing, it has shown that it can handle our marine environment and deliver good, crisp sounding communications while underway. The dry bag keeps water out and the zipper stays secure despite impact from waves and other elements. The headset remains secure in place and gives great audio clarity and volume. The dry bag is excellently sealed on all edges and especially where the connecting cable exits the dry bag and the PTT component is watertight.
