Used to expand or renew the system, the Add-A-Dog SDR-AX receiver integrates with the primary transmitter to maintain synchronized cues across dogs during drills, retrieves, and field trials. Its waterproof construction supports field use in rain, mud, and shallow water, keeping the device ready for upland or waterfowl work. The adjustable neck fit helps secure the unit during rapid movement and retrieves, while long battery life reduces downtime between sessions. A two-hour recharge cycle returns the receiver to service, supporting long practice days in the field. When replacing a worn collar, you can swap the receiver without reloading transmitter settings; when adding a dog, you extend your training setup without changing the core system. For care, rinse mud after field use and dry the unit before storage; inspect seals and connectors periodically to ensure proper performance. Use in regular field training routines to reinforce obedience and retrieve reliability under realistic hunting conditions.
