  • Excellent training Collar and very accurate
Style: Alpha TT 25
I paired this collar with a Pro 550 Plus and they work excellent together for training with my German shorthaired. Very easy to pair and use one you learn all of the functions. The layout of the low/med/high stimulation is easy to get used to for training and the correction of bad behavior and provides peace of mind when working with a young dog off leash. The gps is very accurate down to the foot. The light feature is awesome at night and is very bright. The battery in the collar long outlives the remote. Used in some heavy rain and worked without issue. I have only paired and used one collar so far but highly recommend regardless of the price. ... show more
