Finally got to try the new collar out this evening. Call came in before church and I went right after. Good buck shot about 7 this morning. Took spark in to the shot site and she takes off. This collar is the bomb. She worked the trail up to where they lost blood and she hooked a hard right. Ended up getting the deer up and she ran it almost all the way back to where we started tracking and I toned her off of it. It ran probably 400 yards or so with her in hot pursuit and me and the hunters friend believe it ain't hit hard enough. Hunter shot it with a 22 250.
