SportDOG FieldTrainer SD-425 Training E-Collar
A 500 yards operation radius coupled with 7 correction adjustable levels makes the SportDOG SD-425 a great E-collar. Also, both remote and collar are waterproof and can withstand submersion into the water for a depth of 25 feet.
A lithium-ion rechargeable battery powers both the transmitter and a signal receiver. Also, there’s a charge level indicator on both of them so that you don’t get caught unawares when out of charge. Flexibility is provided by the expansion to three dogs training.
