The first bite indication system designed to embrace modern carp fishing, the Siren R4 is the new standard for precise and responsive indication whether you are fishing on a heavily pressured English lake or a large expanse of European water. Never before have so many advanced features been packed into a single bite alarm.

Building on the market-leading and exclusive "speed difference" indication concept by Kevin Nash from the R3, the R4 offers levels of control and functionality that connect the angler directly with the rig on the bottom in a way never seen or felt before. Intelligent Sensing has become even smarter.

SENSITIVITY

Practically, the R4 will respond to every type of indication caused by carp in any environment. The detail of the available sensitivity settings is less important than the final result: even if the rod tips move due to weed buildup or wave action over thousands of hectares of water, the R4 will tell you everything you need to know without you doing anything. Never before has a bite alarm been able to exclude unwanted events that cause false alarms.

Roller Wheel Sensing - Wheel Sensitivity

The factory setting of the R4 is standard line movement detection via the wheel. Although replaced by Speed Sensing, it still has specific applications, including winter ice fishing.

Speed Sensing

Two levels of speed detection respond faster to line movement at 1cm and 2cm per second respectively, eliminating false indications. Both settings are equipped with the innovative Drift Sensing Safeguard.

Wave Sensing

Two additional sensitivity settings feature Wave Sensing technology to eliminate false indications caused by waves or when fishing from a boat. Events are signaled with fast movements of 1cm or 2cm per second and after 15 or 30cm of back-and-forth wheel movement. Both detection settings also include the Drift Sensing Safeguard functionality.

Drift Sensing Safeguard

Another exclusive feature, the R4's Drift Sensing Safeguard protects against the rare possibility that the line may slip off the spool due to, for example, weed buildup on the line when pressure and line movement are insufficient to activate the Speed Sensing system.

Drop Back Sensing

All R4 sensitivity settings include drop back detection with a descending tone to differentiate it from the take tone.

Guiding Light

The original "homecoming" mode is the ace up the sleeve of the R4 features, designed specifically for anglers using a boat, featuring an LED located on the back of the alarm which, when illuminated, provides a reference point for navigating back to the bank during nighttime hours.

Night Glo

To complete the launch of the revolutionary R4 alarms, the new Night Glo indicator range connects directly to the R4 alarms to illuminate, via LED, the Night Glo Bobbin or Swing Arm indicator head each time the alarm emits a light indication. The indicator bodies are coordinated with the R4 alarm LED color options, with an additional option for black indicators with a white LED light.
