RE: Dog Training Collars
Not sure about the TriTronics brand, but I bought the Innotek ADV300 a year ago and have no complaints with it. I was amazed at how long the battery lasted before needing recharged. The first charge lasted a couple months! I think that 300 yards is plenty of range for waterfowl retrievers. Keep in mind that the transmitter is only water resistant.......not water proof.
