Fantastic headsets


This purchase is a gift for my son who is moving to Corfu to live on a yatch and he states the headsets are Awesome. The range and clarity is superb.

Great for recovery/towing work when you got a crew.


Used these for the first time on a recovery. Didn't think I needed them for years, but I was wrong! Made everything so much easier and the clarity was great. Wish I would have gotten sooner.

Don’t wait.


This is a terrific tool for any owner/captain of a large boat. I resisted for a long time but very happy with the product and the purchase process.
