After five long years of intense development and meticulous testing, Trakker has unleashed the DB7-R Bite Alarm Set—a definitive milestone in bite indication technology. Engineered from the ground up to meet the unrelenting demands of dedicated specimen and carp anglers, this 3-rod presentation set is built to perform when everything else fails.
With advanced digital circuitry, rugged weatherproofing, and cutting-edge features like the Intelli-Sense Mode, the DB7-R ensures you never miss a critical take while completely eliminating the frustration of false indications. When you need bulletproof reliability on the bank, this is the kit you trust.
Power-On Protection System (PS): Say goodbye to accidental power-ups in your kit bag. This clever design prevents the alarms from turning on while packed away, ensuring your batteries are fresh and fully charged for when you hit the water.
Intelli-Sense Mode (ISM): This is where the DB7-R completely outclasses standard alarms. ISM uses advanced processing to filter out false indications caused by heavy wave action, high winds, or when fishing from a boat. It only alerts you when a genuine fish movement occurs.
Db-Mag Roller: Featuring 8 precision-engineered magnets and a high-performance O-ring, this roller mechanism delivers ultra-precise, true indication in any weather context, from freezing winter frosts to blistering summer heat.
Sync-Connect Receiver Technology (SRT): Built with long-range and obstacle-link signal optimization. Even when heavy bankside vegetation, trees, or tricky terrain stand between you and your rods, the SRT system guarantees a crystal-clear, instantaneous signal to your receiver.
Dual-Descent Tone Differential: Instantly know what your quarry is doing. The alarm delivers a distinct, dual-descent dropping tone for drop-back bites, alongside a flashing latching LED, giving you immediate audio and visual clarity.
Customisable Multi-Colour LEDs: Easily switch between 6 vibrant colours (Red, Green, Blue, Yellow, Purple, and White) with the simple press of a button. The Peek-View LED positioning means you can easily see the visual indication even at extreme side angles.
| Feature | Specification |
| Dimensions | 11.2 (L) x 5.4 (W) x 4.5 (H) cm |
| Weight | 98g per alarm |
| Material | Heavy-duty, toughened ABS weatherproofed case |
| Power Requirement | 1 x PP3 9V Battery (per alarm) |
| Output Socket | 2.5mm power out socket for illuminated indicators |
| Adjustment Wheels | 8 indexed volume settings (including silent), 8 tone settings, 8 sensitivity settings |
| Thread Type | Rigid 3/8″ stainless steel thread with blackout locking nut |
| Protection Included | Supplied with a premium, molded Sure-Fit protective rubber case |
| Compatibility | Fully compatible with the Db7-R Receiver |
Large, Windswept UK Syndicates: When big waters experience massive surface waves and undertows, activate the Intelli-Sense Mode to keep your presentation dead silent until a fish actually hooks up.
European Boat Fishing Safaris: Perfect for anchoring up on massive continental reservoirs or rivers where boat movement can wreck standard roller wheel alarms.
Overnight and Multi-Day Sessions: The one-touch night light function drops both LEDs to 25% brightness, offering a subtle, non-intrusive glow that helps you instantly locate your rods in pitch-black conditions without blinding you or spooking fish in the margins.
Maximise your battery and stealth: When setting up for a session where you are fishing close to heavy snags, turn the volume wheel on the alarm down to zero (silent) and rely entirely on the SRT receiver link in your pocket or bivvy. This keeps your presence on the bank completely covert, prevents spooking big fish in the margins, and ensures you get the instant reaction time needed before a carp can bury itself in cover.
Q: Are these alarms completely waterproof?
A: Yes. The DB7-R features a fully sealed, tough ABS weatherproofed outer casing alongside internally weatherproofed digital circuitry and sealed battery compartments. They are designed to withstand relentless torrential rain and freezing bankside conditions.
Q: How do I change the LED colours on the alarms?
A: Changing the colours is incredibly simple. There is no need for complicated programming; you can cycle through the six available options (Red, Green, Blue, Yellow, Purple, White) using a dedicated button directly on the face of the alarm.
Q: What is the benefit of the 8-magnet roller wheel over standard wheels?
A: Standard alarms often use 2 or 4 magnets, which means the line has to travel further before the alarm registers a bleep. The Db-Mag’s 8-magnet configuration increases sensitivity drastically, registering incredibly short line movements—essential when targeting cagey, slow-moving winter fish.
Q: Do these alarms come with a receiver?
A: This specific pack is the 3-rod alarm set. The matching Db7-R Receiver and individual presentation add-on sets are available separately to allow you to customise your setup exactly how you want it.
