I took a look at the site you mentioned. Most of the units are
something like units that are, or were, available here, basic units.
Here just about everything is a 406 unit, then their are those with
built in GPS to send out your position along with other information,
those get expensive. You may also have exchange rate advantages when it
comes to importing these units as well. We have a lot of boats here in
the states, and many operators just don't know what their doing, these
kinds of units in everyones hands could cause more problems. They buy
an automatic unit, stick it in the cabin, go out for a joy ride, hit a
wave, and ride around with the thing activated (you would be amazed at
how many boats their are here that never leave the bay, or the dock on
a cloudy day, that have more electronics on then than a 747). Their
have been more than a few times the CG has responded and found the unit
was on land in someones garage or in a boat being trailered.

And you also don't want to give people a false sense of security with
these things, they may push their luck with a too small or poorly built
boat. If you get into trouble, and the EPIRB works, great. But have a
"Plan B" ready, these things can fail. Keep the boat afloat as long as
possible, have tools on hand to do so. Get out a distress call ASAP,
have good life preservers, a raft is a great idea, let people know
where you intend to go before leaving the dock, have good flares, a
hand held VHF in a waterproof case is great to have. Know where all
this equipment is, and keep it in good working order.

My point is, when things go bad, you should know what to do before
hand. Because everyone is going to be looking to you for guidance.

I've been in one of these bad situations before, and got away with it.
I'm a lot smarter now because of it. I don't push my luck like I used
to, and I'm prepared.
