SportDOG FieldTrainer SD-425S Remote Trainer

The SportDOG SD-425S is a robust short-range remote trainer built for field training, hunting, farming, tracking, K9 training, competition training and obedience training. The SD-425S remote trainer delivers higher static stimulation levels for high-drive working dogs and tolerant pet dogs above 5kg.

The system has a 450m range and is expandable up to 3 dogs (with additional receiver collars). The collar features 7 levels of 'medium' static stimulation and 7 levels of 'high' static stimulation. The medium stimulations are recommended for tolerant dogs in suburban/controlled environments while the high stimulations are recommended for tolerant dogs working environments. Using the rheostat dial located at the top of the handheld remote trainer, you can quickly fine-tune the levels to match your dog's drive. The remote trainer features nick stimulations and continuous stimulations as well as static-less functions including tone-only and vibration-only. The system is completely waterproof submersible and rechargeable.

How the SportDOG SD-425S Works

How it Works: The SportDOG SD-425S has two main components; the handheld remote and the receiver collar. When you press a button on your remote transmitter, a radio signal will be sent to your dog's receiver collar and delivers the selected stimulation through the contact probes. With proper training, your dog will learn to associate the stimulation with a specific command or behaviour.

Remote Functions:

Levels 1-7 (Static stimulation)

Using the rheostat dial on your remote transmitter, you can quickly fine-tune the stimulation output between levels 1 and 7 (1 being the lowest and 7 being the highest). 

Nick Stimulation

When the nick stimulation button is pressed, the collar will deliver a momentary stimulation regardless of how long the button is pressed for.

Continuous Stimulation

When the continuous stimulation is pressed, the collar will deliver static stimulation for the length of time the button is pressed for (for a maximum of 10 seconds). To continue the stimulation, release the button and press the button again.

V/T (Non-static stimulation)

Vibration-only and Tone-only stimulation.

Things to Consider

The SportDOG SD-425S has a maximum line-of-sight range of 450m. Weather, terrain, vegetation, transmission from other radio devices and other factors may affect the maximum range. If you need a remote trainer with a longer range, please view the following SportDOG Remote Trainers.

The SportDOG SD-425S is expandable up to 3 dogs with additional collars. If you need to train more than 3 dogs, please consider the following products:

The SportDOG SD-425S has medium to high static stimulation levels recommended for tolerant dogs. If your dog is timid or easily responsive, we recommend considering the SportDOG 425E or Dogtra iQ Plus Remote Trainer. These remote trainers have lower levels of static stimulation suitable for more responsive dogs.
