thanks for the advice, extremely helpful,I am training my golden for quail hunting, and i've done all i think i can do verbally. my golden loves to point and retrieve, the only problems i'm having is that she gets to far ahead of me and doesn't want to come back on comand. I think she needs just a little more incinitive. So I'm not looking for anything waterproof, mainly just need something for distance and one I can adjust the power. If you have any ideas i'd loved to hear,THANKS.
