I used to have a trx3 with 3 collars and loved it very very accurate I now have trx10s still playing with it but seems to have good accuracy and range. By far the best collars are johnson 16000 always used them and they have better range and strenght than my wild life or rats collars. plus u can get them on sale for $100 right now through johnson. trx 3 with antenna and 1 collar is like $550 unless u can find a used one.
