I am looking into buying this collar/ beeper. Can anyone tell me if this is a good one? I do lots and lots of grouse hunting in thick cover. My Sportdog 400s just doesn't cut it. I thought it was a good one from reading the box but it is only good for yard/ field work. I don't want to get another one that won't work.

I have the Upland G2 with the beeper option and love it.  Good range with lots of settings, and it is waterproof too.  Beeper option is nice, because I hunt in thick cover and can't see the dog or loose site of her sometimes, so I page her with the beeper to see where she is at and if she is moving, it has a different beep when she is moving or on point (not moving).  When I first started using the combo, I have a whistle command I use to come in, then I would page her with the beeper, and if she doesn't come, I would blow the whistle once more then I would stimulate her until she did.  If she is on point I will go to her.  Never stimulate if your dog is on point.  I haven't used the e-collar part in two years, just the beeper every now and then.
