EPIRB
We've got the ACR 406, non GPS, mounted in the same position as Dan-I agree that there is some risk, but it's readily grabable if you need to abandon ship, and if you're sheltering below you can trigger it without going topsides. the auto cockpit mounts are a theft temptation and have been known to be lost in a capsize or heavy seas. Even though they are not supposed to open until they're under 10ft of water, they have tripped when you don't want them to. I would get either the GPS linked unit Dan has, or the one with the built in GPS-the main diff is that the linked unit updates from your GPS, so it always knows your boat position. The built in must do a cold start for the GPS, which can take several minutes before it has a position to transmit-otoh, it's a stand alone unit. You save a couple hundred $ by getting the non GPS unit-I'm told that it may take up to 45 minutes for the satellite sytem to generate an approx position for the non gps unit, and it's a much larger search area. I'd spend the money if I didn't already have the earlier model
