This product seems overpriced at first glance. But then, how much is your marriage worth? The Eartec just function without drama, allowing you to communicate with your first mate at a whisper, even when there is serious engine noise in the background and they are at the other end of the boat and out of sight. Yelling and cursing are no longer a part of the boat trailer unloading, dock departure, boat docking and loading onto the boat trailer routines. Hand signals that never seem to make sense are no longer needed. The units do not require any fiddling with to sync up and user instructions on use can be boiled down to "put the headset on and speak into the microphone". The units are full duplex so you both can be speaking and listening to the other simultaneously, unlike walkie talkies, and both hands are free to tend to the rudder and lines. The construction quality is excellent. We use lanyards around our necks to keep them from accidentally falling into the drink when we bend over the railing or bump our head on something. Battery life is good, with one caveat. The "slave" units do not have an on-off switch, unlike the master, and the battery will run down if left in. We make a practice of removing the batteries from both the master and slave headsets after we are finished using them. We have an extra set of charged batteries along, but we have never needed to use them since the batteries seem to last for hours when used properly. This is one of the best purchases we have made for our boating activities. Because there is no need to raise voices to be heard, everything is calmer and the whole experience much more pleasant, even during the inevitable moments of excitement and stress.
