Overview

The SportDOG FieldTrainer 425X is a remote training collar with a 500 yard range, waterproof housing and a rechargeable receiver, built for off leash obedience work with 21 levels of static, tone and vibration correction.

This sits in SportDOG's training collar line rather than a containment fence system, so it works off a handheld remote rather than buried wire or a beacon. It ranks around 19th among electronic training collars on Amazon, and ships with both long and standard contact points to fit different coat lengths.

  • 500 yard range
  • 21 levels of static, tone and vibration
  • Waterproof, quick charge collar
  • Long and standard contact points included

Who it's for

Owners training a dog for off leash obedience or field work who want adjustable static, tone and vibration correction from a handheld remote. Not built for anyone who needs a boundary or containment fence system instead.
