The Avid Carp VTX 4+1 Bite Alarm Set is a high-performance, technologically advanced bite detection system designed for the dedicated long-session angler. This comprehensive kit includes four alarm heads and a dedicated receiver, all finished in a rugged, weather-sealed housing. The standout feature is the Bi-Directional Sensing, which allows the alarms to differentiate between a standard run and a drop-back, providing you with total clarity on exactly what is happening at the hookbait.
At Gerry’s Fishing, we recommend the VTX set for anglers who prioritize reliability and security. With its SafeGuard Anti-Theft system and long-range signal stability, this set offers peace of mind whether you are sleeping in your bivvy or fishing at a distance from your rods.

Bi-Directional Roller Sensing: The internal roller wheel features 8 levels of sensitivity. It is designed to detect both forward pulls and backward drop-backs, ensuring that even the most cautious of “fussy” takes are registered.
Multi-Light LED System: Each alarm head features high-visibility twin LEDs. You can cycle through four color options (Red, Yellow, Green, Blue) via soft-touch side buttons, allowing you to color-code your rods or match your personal preference.
SafeGuard Anti-Theft System: A vital security feature for the modern angler. If an alarm head is powered off while the receiver is on, a warning alert is triggered, deterring potential tackle thieves.
EPS Receiver Compatibility: The receiver utilizes an Enhanced Positioning Signal for a rock-solid connection up to 150m. It also features a Bleep Memory Function, allowing you to see which rod was triggered last if you happen to miss the initial sound.
Weather-Sealed Durability: The digital internals are housed in a fully weather-sealed case, protecting them from rain, frost, and condensation. The Piezo speaker ensures the tone remains crisp and clear even in extreme weather.
Rod-Friendly Design: The “Deep Ears” of the alarm feature soft rubber inlays. These provide excellent grip on the rod blank, preventing the rod from being pulled out of the alarm during a violent “wrap-around” take.
Smart Power Management: The system is powered by standard AAA batteries. A dedicated Cyan LED indicates low battery levels, and the receiver provides a power-on battery status check so you are never caught out mid-session.
Customization: You can fine-tune your setup with independent dials for volume and sensitivity, plus side buttons for tone and LED settings.
Versatility: The 2.5mm power-out socket is universal, meaning you can easily connect your favorite illuminated bobbins or swingers.
Complete Package: The inclusion of clip-on hardcases, a lanyard for the receiver, and even a screwdriver for battery changes means this set is truly ready to go “out of the box.”
The Avid Carp VTX 4+1 Set offers a professional-grade feature set at a very competitive price point. The build quality feels substantial, and the inclusion of anti-theft and drop-back sensing makes it much more than just a standard “buzzer.” It is a reliable, modern system that looks as good as it performs.
Gerry’s Pro Tip: When setting your sensitivity, use the lower settings (higher number) for windy days or flowing water to prevent “ghost” bleeps. For winter fishing when takes can be incredibly subtle, dial it up to the highest sensitivity to ensure you see every slight movement of the roller
