Not sure my question made it up on the site--does the hood fit over a helmet?

Does the hood fit over a helmet?

Thanks for the international registration site. I have never done so much homework before making a purchase in my life! So. I could buy this thing from BC, have it shipped over to France and register it using the international registration website, and that would set it up in such a way that when activated, the SAR authorities in France would be the ones to be notified, as opposed to the NOAA guys, even though I bought the beacon in the US? In the interest of saving time, I'd like to have the French SAR people respond without having to have the message be routed first through the US. Can I do this by registering it on the international site? Thanks!

Where exactly on the www.acrplb.com site is there a link to register a PLB? I'd like to buy this from BC and register it in FRance, which is where I live for the time being. Can I do that myself, or does the PLB have to be taken to some sort of professional?

Can anyone tell me what the difference is between the "I" and "I/O" models is? According to the owner's manual, both transmit over 406 MHz, and also over 121.5MHz. So that, I take it is not it. On page 15 of the manual, though, they spend a lot of time talking about DOWNLOADING INFO FROM AN EXTERNAL GPS RECEIVER--if the units already have an on-board GPS receiver, why would this be necessary? Is it a back-up? Because they also talk about the On-board GPS acquiring new data, but they also say that the I/O model is the only one that does that. Does the "I" stand for "Interface," and the "O" stand for "on-board?" Does that mean that the I/O has an on-board receiver that can be used to determine LAT/LON and that the I PLB requires an external receiver to get that info? Basically, is the difference that the "I" model needs the coordinates to be acquired using an external GPS receiver because the "I" model doesn't have one, and the "I/O" model DOES have a receiver?

Hi, I'm looking at the ACR Terrafix 406 I PLB and the Terrafix 406 I/O PLB, and have a few questions concerning the two models:1) Do both models have an integrated GPS? If so, what does the "interface" for the I/O stand for? Is that for an interface with an external GPS unit? If the I/O already has a GPS unit, why would one need to connect it to an external one? 2) What is the difference in the price between the two models due to? 3) Is there any difference between the two in terms of efficiency or reliability? Is one "faster" than the other? 4) I plan to use this unit essentially in Europe, although I will purchase it in the US--will it be difficult to register it in France?

I take it this thing can be used in Europe--does anything have to be done in terms of using a modified signal, or anything like that?
