Comment / Questions about SportDOG FieldTrainer 425 2-Dog Remote Trainer... (Dogs 8 Pounds and Up)

September 08, 2015

a couple years ago I bought your training colars 2 recievers.. one controler.. one of the recievers has gone bad and I need a replacment that works with the controler.. the only info I have is on the controler it is ST-120b


This is an older unit so you will need to contact Sport Dog Directly. Perhaps they can recommend a newer transmitter that will be compatible.

Hello I'm curious that with the SD-425 dual collar system am I able to shock one dog without shocking the other using a single remote?


That is correct. Your two dogs will be independently corrected on the SD-425 two dog training system. Both collars will be controlled with a single hand held remote transmitter.
