Limited experience with only two guided hunts, but both allowed us to bring dogs. This latest we elected not to because we thought we’d be in a group with others. Turned out it was just and the guide, wish we had brought our dogs. Guide dog on day one was horrible.
I’ve got a PH2 in 6CM, absolutely fantastic gun. Haven’t had to use the warranty yet, so I can’t speak on that end of things. Gun is a tack driver with ELDM.
Yes, the whip antenna is for the UHF to communicate with the collar, so you should be good to go. I've got one handy (great upgrade over the 100) if you have any other questions.
