I recently bought my first e-collar, a tri-tronics G2 Pro 500, and also picked up their beeper collar. I've hunted with dogs with beeper collars, and while they are a great benefit in heavy cover, they gave me a headache. I can only imagine how aggravating they are to the dog wearing them.
I have decided to reserve the beepers use to hunts in heavy cover, and then to be turned on remotely only when needed.
E-collars are worn pretty tight. I always try to get first hand, face to face advice from someone who knows and can actually demonstrate in person, when it comes to something like this. It's difficult to explain how tight a collar should be in print.
Good luck with your dog.
