I have a Sport Dog 425. no issues, works great with my Field Bred Springer. Good range of "power".
water proof . do a lot of woodcock hunting and she is a swimmer.
I use low setting, just enough to tickle her and she knows the correction.
I call it my "Mollie Remote". but I rarely have to remind her. when she has the collar on, she knows!!
