How far away would you be able to hear the beeper collar?
Once you go GPS you will never go back! It's absolutely amazing to be able to go into the thickest of cover and have complete confidence you will get to every rooster.
I too was worried about cost so I went with the SportDog TEK V1.0. It does not have all the functionality of the garmin but it is a shock & GPS in one unit. I picked up mine for $440 shipped.
It's absolutely awesome to completely loose sight of your dog in a marsh and then all of a sudden your handheld will vibrate signaling that the dog's on point, x number of yards west. I've almost run into the dog he was pointed in such thick cover before noticing him.
I can attribute 2 roosters this season to the GPS (picked up 3 weeks ago). Without it they would have flown or run off before I ever found the dog.
Good luck on your quest!
This is a nice product except for one thing. Unless you have PERFECT hearing you will not be able to hear the beeps from the collar or the hand held receiver. The Point Notification Mode can be set to vibration and/ or beep. You have to be holding the receiver in your hand to feel the vibration, if stuck in your vest or pocket with any layer of hunting clothes you won't feel it. The on-point beep notification is a VERY VERY WEAK non-adjustable high frequency tone. If you have any hearing loss at all, which most of us veteran hunters do, you cannot hear it unless held very close to your ear. Sportdog needs to modify this notification function to a fully adjustable sound across the frequency spectrum with volume control.
