Thanks for the advice. Yes, he is going with a group and a guide. I looked into the one you suggested, which says dual antenna. But some of the other models have 3 antenna now?? Does that matter? I won't be there and I'm nervous. Hopefully he won't ever need it, but if he did, I would hate to have gotten a lesser model.
Sorry, I'm a novice with this. I like to sit and read, he likes to do all this crazy stuff. I'm just looking out
Number of antennas only matters when the unit is in search mode (.i.e., when looking for somebody else). For keeping him safe it makes no difference (unless you are buying beacons for the whole group).
Edit: Oops, just noticed that Snowolf beat me to it already. Anyway, you got the answer to your question.
