D.T. SYSTEMS H2O Receiver Collar

The D.T. Systems H2O Receiver Collar is an add-on training receiver designed to expand existing H2O 1800 PLUS series electronic dog training systems into multi-dog operations. This replacement collar integrates seamlessly with DT Systems' proven digital training technology, allowing trainers to scale their system capacity without replacing core equipment or restarting the programming process.

The H2O Receiver Collar is compatible with any H2O 1800 PLUS system (excluding Beeper models) and serves dual purposes: adding a second or third collar to expand training capacity, or replacing a damaged or lost collar within an existing system. Programming to your active system is fast and straightforward, minimizing downtime between training sessions. The compact footprint (5.65 x 2.35 x 7.85 inches, 0.77 lbs) ensures reliable fit for varied canine sizes and field conditions.

This collar is essential for handlers operating multi-dog teams—law enforcement K-9 units, search and rescue operations, hunting guides, and professional trainers—who require simultaneous control and reinforcement across multiple animals. The H2O 1800 PLUS platform's digital architecture delivers consistent stimulus delivery and range performance, critical for consistent obedience training and safety in field operations. By purchasing the H2O Receiver Collar, users avoid the expense of a complete new system while maintaining compatibility with their existing remote transmitter and training protocols.

DT Systems is recognized in the professional dog training market for durable, field-proven electronic collars used across law enforcement, military, and civilian sectors. The H2O line represents their mid-to-professional tier, balancing reliability with accessible pricing for serious trainers managing multiple working dogs. Stocking this receiver collar ensures you maintain operational continuity without excess inventory of backup systems.
