E-Collar K9-400 K9 Handler – Tactical Training Collar for Working Dogs, 3/4 Mile

E-Collar K9-400 K9 Handler – Tactical Edition for Working Dogs

The K9-400 K9 Handler by E-Collar Technologies is a tactical remote dog training collar built for working dogs, service dogs, and large or double-coated breeds. The training engine is identical to the ET-400 (3/4 mile range), but it ships with dedicated tactical accessories.

What sets the K9-400 apart

The differentiator is the tactical package: a 33" bungee strap that tightens and releases as your dog's neck expands under exertion — keeping contact optimal and constant; thick 3/4" contact points especially suited to long and double coats (German Shepherds, for example); a quick-release belt clip; and a hard carrying case. Beyond that, every 400-series capability: smooth "blunt" stimulation with 100 levels, Boost (1–60), tone and vibration, Lock & Set, a night light and a floating transmitter.

Who is it for?

For working and service dogs, large breeds, and double-coated dogs that need reliable contact and extra durability. The RX-090 receiver (about 2.4 oz) is waterproof and the transmitter floats — ideal for field training and water environments. Range up to 3/4 mile. Expandable to two dogs with an additional receiver.
