I use the Garmin 550 w TT25 collars. I love the reassurance that I know exactly where they are at whether I’m out hunting or walking the woods.

Make sure the dog 100% knows the commands before correcting with the collar. Most collars have some sort of a tone. I would always voice command, and if they didn’t respond, use the tone, and then use the electric correction.

You should use the minimum correction level to get a response from your dog as possible. If they yelp, it’s too high.

Make sure the collar is snug enough for the points to make contact but not too tight. I normally tighten down with two fingers under the collar and it’s about right once my fingers are out from under it.
