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.

Who it's for
