Multi-Colour L.E.D Choose between 6 colour options at the push of a button. Red, Green, Blue, Yellow, Purple & White. Pro-Sync Once Paired, automatically synchronises the Bite alarm settings to the receiver, so you will only have to adjust your preferred Tone and L.E.D colour settings on the bite alarm unit once. Mute Mode The classically styled and very functional 3 stage toggle switch offers a mute mode (Middle Position). Which also activates a curtesy light (Drop Back White L.E.D) on the Bite alarm. Allowing the angler not only to adjust and set their bobbins in perfect silence, but also without the use of a headtorch. The night lights use energy efficient low battery consumption technology. The night lights operate at only 30% of their total brightness ensuring battery consumption is kept to a very minimum. Fitted within the forward facing & extending snag ears and underneath the roller wheel. Bite-Tec Automatically cancels out the night light functions aiding for a much clearer visual presence when a bite is in progress and automatically resets itself after latching light sequence. Pro-Sec alerts the angler both visually and audible via the receiver that the Bite alarm has been turned off. Bite & Light Integral 2 brightness settings Bivvy Light can be set to automatically Illuminate when a bite is in progress. Helping you make for a much quicker response time while illuminating the Bivvy as well as your exit route - move On/Off switch in to middle position. DSR – Digitally Synchronised Roller By increasing the size of the 4-magnet roller wheel and with the help of some very clever technological advances. Has allowed us to offer a much wider spectrum of sensitivity settings while keeping the adjustment needed to a minimum. This helps eliminate false bites and greatly reduces the alarms being triggered prematurely by water movement and environmentally distrbances such as wind and floating weed.
