The ECU MK1 Super Plus Compact Remote Bite Alarm 3 Rod Set is a three-alarm system with a matching remote receiver, designed for carp and specimen anglers who want reliable bite indication at distance. The alarms use Enhanced Speed Bite Detection Sensing technology to register fast takes, while a mute function lets you silence the unit with one press for 30 seconds or two taps for 60 seconds. A super-large single latching and run LED combines with a multi-colour LED that can be set to any colour via the LC-D button. The alarm also includes a dimmer function, separate volume, tone, and sensitivity buttons, and a silent mode for discreet use. A low battery indicator window sits alongside the toggle switch. The roller wheel is anti line skip, stopping line from jumping over it, and features a slick glide design for increased movement of light lines over the wheel. Vertical isotope slots take 12mm x 2mm isotopes. A drop back function gives visual and audible differentiation between forward and reverse movement. Rod riser storm ears are included to increase angled rod height elevation. The alarm has an extended signal range thanks to an external base drop-down antenna, and a 2.5mm jack output socket for illuminated hangers (hangers will become available separately). The SUPER+ remote receiver offers volume control and a vibration feature, plus a low battery warning indicator. A programme button pairs alarms, while a reset button erases alarms and wipes receiver memory. Signal range reaches up to 200m. All four LEDs on the receiver can be changed to any colour preference with a simple press of the LC-D button, and there is a dimmer LED function. The receiver has a central isotope slot that takes a 12mm x 2mm isotope; the manufacturer recommends bedding the isotope down with new Blu-Tac, so you can pick it out with a fine needle if needed, reducing the chance of cracking it. - Enhanced Speed Bite Detection Sensing technology - Mute function (M button, one press 30 sec mute / two taps 60 sec mute) - Super Large Single Latching / Run led combined, multi colour led can be set to any colour (LC-D button) - Dimmer Function - Volume, tone, sensitivity buttons - Silent mode function - Low battery indicator window alongside toggle switch - Anti line skip roller wheel (stop line skipping over roller wheel) - Slick glide roller wheel feature (for increased light line movement over roller wheel) - Vertical isotope slots take 12mm x 2mm size isotopes - Drop Back Function, visual and audible differentiation between forward and reverse movement - Rod riser storm ears included for increased angled rod height elevation - Extended signal range with external base drop down antenna - Jack output 2.5mm socket size for illuminated hangers (hangers will become available) - Volume control, vibration feature - Low battery warning indicator - Programme button (to pair alarms) - Reset button (to erase alarms / wipe receiver memory) - Up to 200m signal range - LC-D colour change feature, all 4 LEDs on super+ receiver can be easily changed to any colour preference at a simple press of the LC-D button - Dimmer LED function - Central isotope slot on receiver takes a 12mm x 2mm isotope The Mk1 Compacts is the brand name for a variety of alarm models designed and manufactured by ECU / Scott Edwards.
