The first bite alarm to meet the challenges of the now global carp fishing world. The Siren R4 is the new standard when it comes to accurate and reliable bite indication. Whether at an English park lake or at the largest bodies of water in Europe.

Never before have so many revolutionary features been combined into one world-class package. Based on Kevin Nash's leading "Speed ​​response indication concept" of the feature like never before. Nash makes "Intelligent Sensing" even smarter.

Exactly how the various settings work is less important than the fact that they result in the R4 being able to give signals when it matters most in every imaginable situation, even in the biggest storm or when fishing from a boat and to be silent if not. Never before has there been a bite alarm that was so intelligent in avoiding unnecessary beeps.

Roller Wheel Sensing

The factory setting for the R4 is the classic measurement of the rotation of the wheel inside. Even if the "Speed ​​Sensing" is clearly superior in normal cases, this setting has its place. For example when fishing with zigs in winter when very slow bites are to be expected.

Speed ​​Sensing

Two selectable levels of "Speed ​​Sensing" react to the speed of the line withdrawal - faster than 1cm or 2cm per second to prevent unnecessary beeps. Both settings also use the “Drift Sensing Safeguard”.

Wave Sensing

Two other settings use the new “Wave Sensing Technology” to eliminate individual beeps when waves hit or when fishing from a boat. Depending on the setting, the bite alarm reacts at 1cm or 2cm line pull-off per second and after 15 or 30cm line pull-off forwards or backwards via the wheel. Both "Wave Sensing" settings also use the "Drift Sensing Safeguard".

Drift Sensing Safe Guard

Another revolutionary innovation of the R4 is the “Drift Sensing Safeguard”. This prevents slow-moving objects such as floating weed or thread algae from pulling line off the reel unnoticed, without the speed sensing of the bite alarm indicating this.

Drop Back Sensing

All settings of the R4 provide a drop bite indicator that uses a double descending, lower tone to signal the direction of line movement.

Guiding Light

The innovative 'Homecoming Mode' is the R4's feature ace - designed with the boat angler in mind, it offers a rear integrated LED which, when switched on, provides the angler with a reference point for safe and straight forward boat navigation on the return trip.

Night Glo

Matching the launch of the revolutionary R4 bite alarm, the Night Glo range appears. Novel optical bite alarms, which can be connected directly to your R4. Connection to the bite alarm's power supply will result in the Night Glo Bobbins or Swing Arm Heads lighting up whenever the bite alarm's LED is illuminated. Available in colors to match the R4's LED options, plus a black version with a white LED inside.
