Good communication is crucial on board, and If you've ever tried to converse with someone at the helm when there's a dodger in the way or when the wind is blowing, you'll appreciate this new headset from Eartec. It features a full duplex system, which allows the crew to converse simultaneously with no buttons to push and no delay. The Comstar UltraLITE can support up to eight crew members. It's not voice activated—just simply turn it on and talk. The system includes deluxe padded headsets and Comstar belt packs that weigh only 2.5 ounces.
