NASH Siren R4 Receiver

The R4 Receiver offers accurate high power remote performance at ranges over 750 metres – with exact tone replication, and exact LED colour replication from each programmed R4 head.

In addition the R4 Receiver controls the R4’s unique Homecoming Mode. The rear LED on one R4 alarm can be selected and illuminated as a direction guide, or all R4 rear LEDs can be illuminated simultaneously to show exactly where alarms are positioned and to help navigate safely between lines – a routine hazard when returning from a boat battle or dropping a rig.

In most circumstances the feature is a great practical help, but in extreme weather, fog, big winds and driving rain or when long battles can easily disorientate you it is a safety feature that sets the R4 Receiver and R4 alarm combination apart.

Using the same high power transmission as the remote signal between R4 alarms and Receiver the rear LED function can be triggered from up to 750 metres to illuminate your alarms and light your way back to your swim no matter how far from base camp you find yourself.
