Need some advice, purchased the tritronics pro 100 G2 a couple of years ago, when tritronics had a blow out sale, the collar was a back up collar and rarely used. In the last couple of months with repair on my other collars, been using the G2 regularly, yesterday the transmittor will not transmitt, collar clinic has an upgrade to the G3 transmittor using the G2 collar, what is more cost effective, fix the existing set or upgrade to the G3? thanks
