It is perfect for those who want to move away from mechanical roller-wheel issues and require advanced sensitivity adjustments for wary fish on technical venues.

In the section below, we have combined genuine angler feedback with our own expert assessment. We examined the key features and specifications to present you with a transparent breakdown of the pros and cons regarding the Delkim TXi-D v2.

Our Verdict: The Delkim Txi-D v2 Bite Alarm

Bite Alarm Type / Range / Type of Motion Sensor / Accessory Compatibility

The Delkim Txi-D v2 is a premium digital bite alarm system featuring an impressive 750 m range and the unique, patented Piezo Vibration Sensing technology instead of a traditional roller wheel.

It offers “Ultimate Weatherproofing” and extensive accessory compatibility, including the new digital SmartLite system and the Rx-D v2 Receiver with its integrated Bivvy Light Mode.

The Delkim Txi-D v2 represents the pinnacle of British carp fishing technology, operating on a sophisticated, fully digital radio system with a staggering 750 m operating range.

Unlike the vast majority of competitors that rely on mechanical magnet-and-roller systems, the Txi-D v2 utilises Delkim’s patented Piezo Vibration Sensing technology.

This sensor is the heart of the system: because it has no moving parts, it is impervious to frost and grit. Crucially, it detects the speed of the line and vibrations from the rod tip, meaning it can register the finest knocks and zupfers that wouldn’t even turn a traditional roller wheel.

The digital radio system ensures crystal-clear signal penetration, transmitting the exact tone and LED colour you have selected on the alarm directly to the Rx-D v2 Receiver.

In terms of build quality, Delkim has upgraded to a new “Ultimate Weatherproofing” standard, using a synthetic rubber coating on the mouldings for 100% waterproof reliability, a significant step up from older acrylic versions.

Accessory compatibility is a major strength of the v2 series. It features a standard 2.5mm NiteLite socket, making it cross-compatible with existing NiteLite hangers. However, the real game-changer is the compatibility with the new SmartLite system.

This “intelligent” hanger connects via the socket but transfers digital data, allowing the hanger to act as an extension of the alarm. Additionally, the system is compatible with third-party tech like the Smart Light 2 by Smart Indicators.

While the alarm itself doesn’t have a built-in bivvy light, the Rx-D v2 receiver compensates brilliantly with its integrated “Bivvy Light Mode”. When an alarm triggers, all LEDs on the receiver illuminate white, acting as immediate emergency lighting in your bivvy so you can find your boots in an instant.

 

Special Indication for Drop-Back Bites / Latching LED / Receiver with Vibrate Mode / Night Light

This system delivers superior visual feedback with multi-coloured LEDs, a 20-second latching LED, and a dedicated “Night Marking” mode for permanent low-level illumination.

It features a fully adjustable receiver vibrate mode for stealthy angling and, when paired with the SmartLite hanger, offers a unique visual and audible indication specifically for drop-back bites.

The Txi-D v2 offers a highly customisable visual display, featuring twin Multi-Coloured LEDs that allow you to cycle through Purple, Red, White, Blue, Green, and Yellow at the touch of a button.

When it comes to Special Drop-Back Indication, the v2 system takes a unique approach. While the alarm produces a distinct sound, the full visual potential is unlocked when paired with the optional SmartLite indicator.

In this combination, a drop-back bite causes the SmartLite hanger to physically flash, while the alarm and receiver play a unique two-tone sound, giving you instant clarification on what the fish is doing.

The unit features a Latching LED duration of 20 seconds on the alarm head, giving you plenty of time to identify the active rod. The receiver supports this with a “RunLite” function that stays lit for 4 seconds after the beeping stops.

For stealthy approaches, the Rx-D v2 receiver boasts a fully adjustable Vibrate Mode, ensuring you don’t miss a take even with the volume turned down.

The alarm head also includes a “Stealth Mode,” which deactivates the LEDs during a run to prevent spooking fish (or alerting other anglers) while keeping the night marking active.

Speaking of night fishing, the Night Light function (“Night Marking”) is superb. With a press of a button, the LEDs emit a permanent, low-level glow in your chosen colour, removing the need for betalights and allowing you to see your rod layout clearly in the dark.

 

Volume / Sensitivity / Tone / Anti-Theft Alarm

The Txi-D v2 provides unmatched adjustability with 32 digital tones and stepless dials for volume (up to 100dB) and sensitivity, further refined by the unique “Beep Speed Control.”

Security is paramount, featuring an Advanced Security System with Anti-Theft Movement Detection (ATMD) that instantly alerts the receiver if an alarm is tampered with.

The Txi-D v2 is famous for its almost infinite adjustability, now made easier with a Simplified User Interface.

Volume is controlled via the analogue “V” dial, offering stepless adjustment from silent (0) right up to a deafening 100dB, ensuring you wake up in the heaviest winds.

Sensitivity is where Delkim truly outshines the competition. You adjust the sensitivity level via the stepless “R” (Response) dial. However, to fine-tune this further, the digital menu offers Beep Speed Control.

This allows you to dictate the relationship between the vibration speed and the beep rate, giving you total control to filter out wind or tow while spotting the shyest bites.

For audio customisation, the Tone settings have been streamlined to 32 digital tones, ranging from low growls to the classic “Delkim Warble.”

Security is paramount on public waters, and the Txi-D v2 features an Advanced Security System with Anti-Theft Movement Detection (ATMD). If anyone attempts to move the alarm head or switch it off while the receiver is on, an immediate alarm is sent to the receiver, providing a robust theft deterrent.

Additionally, a handy Mute Function allows you to silence the speaker for up to 5 minutes—perfect for setting your bobbins without annoying the whole lake.

 

Batteries Required / Box Contents

Both the alarm heads and the receiver are powered by standard, readily available 1 x 9V alkaline batteries, supported by an Auto Power Down feature to conserve energy.

The comprehensive presentation set includes three alarms, the receiver, matching hard cases, and Safe-D Carbon Snag Bars, ensuring you are fully equipped straight out of the box.

Power management on the Delkim Txi-D v2 is efficient and reliable. Both the alarm head and the Rx-D v2 receiver are powered by a standard 1 x 9V PP3 alkaline battery (e.g., Duracell MN 1604).

This is a massive plus for anglers, as 9V batteries are available in almost any petrol station and offer a very long service life.

To further protect battery life, the units feature Auto Power Down, turning themselves off after approximately 48 hours of inactivity, and a Low Battery Warning to ensure you are never caught out.

The box contents for this presentation set are comprehensive. You receive 3 x Txi-D v2 Bite Alarms, 1 x Rx-D v2 Receiver, and 3 x Safe-D Carbon Snag Bars (v2), which fit neatly into the alarm casing.

Protection is guaranteed with 3 x Moulded Hard Cases for the alarms and a clear hard case for the receiver. All necessary batteries are included, so you are ready to fish straight out of the box.

For peace of mind, the standard 2-year warranty can be extended to 3 years simply by registering the product on the Delkim website.

Delkim TXi-D v2: Pros and Cons

The Delkim TXi-D v2 excels due to its unique Piezo Vibration Sensing for unmatched sensitivity, a class-leading 750-metre range, and the patented Anti-Theft Movement Detection (ATMD).

Operation remains simple via wheels rather than menus, all backed by an optional 3-year guarantee.The main drawback is that the alarm head alone cannot distinguish between runs and drop-backs.

To resolve this, the optional SmartLite Indication Set is essential; only when connected does the system unlock full directional detection with distinct tones and LED patterns.

 

Pros

• Purchased and rated by over 5 customers on Amazon and Angling Direct
• 5th place in our comparison
• Class-leading range of up to 750 metres
• Patented Piezo Vibration Sensing technology
• Patented Anti-Theft Movement Detection (ATMD) system
• Optional 3-year guarantee with website registration
• Simple operation using the adjustment wheels

Cons

• SmartLite Indication Set required for drop-back detection

 

When breaking down the performance of the Delkim TXi-D v2, it becomes clear why it remains a firm favourite among serious carpers. Having secured a solid 5th place in our comprehensive comparison, this alarm is backed by positive feedback from verified purchasers on Amazon and Angling Direct.

The system’s biggest strength lies in its patented Piezo Vibration Sensing technology. By doing away with moving parts, it offers a level of sensitivity adjustment that standard alarms simply cannot compete with.

It is also a powerhouse in terms of connectivity and security, boasting a class-leading signal range of up to 750 metres alongside a patented Anti-Theft Movement Detection (ATMD) system. This feature provides an extra layer of security, alerting you immediately should anyone attempt to tamper with your gear.

Despite this advanced tech, operation remains refreshingly simple; the intuitive adjustment wheels allow for quick changes to volume and sensitivity without scrolling through endless digital menus.

However, potential buyers should be aware of one specific technical nuance regarding bite indication. Unlike traditional roller-wheel alarms, the Delkim TXi-D v2 head unit itself does not distinguish between a run and a drop-back due to its vibration sensing technology.

This might catch some anglers out if they are used to standard magnet-wheel systems. However, Delkim has solved this with the optional SmartLite Indication Set.

When connected via the standard 2.5 mm power out socket, this intelligent hanger acts as a direction sensor, unlocking full drop-back functionality with distinct audible tones and LED patterns on both the alarm and the Rx-D v2 receiver. It’s a brilliant add-on for anglers who demand that level of detail.

In summary, while the requirement for the SmartLite set for drop-back differentiation is a slight caveat, the sheer performance and build quality make the TXi-D v2 a formidable piece of kit.

To seal the deal, Delkim offers an optional 3-year guarantee with website registration, giving you total peace of mind regarding your investment.

 

Delkim TXi-D v2: Frequently Asked Questions

 

How many batteries are required in total for the Delkim TXi-D v2 3-rod set?

You will need a total of 4 x 9V (PP3) batteries for the 3-rod presentation set – one for each of the three alarm heads and one for the Rx-D v2 receiver. The good news is that high-quality batteries are already included in the box, so you are ready to start fishing straight away.

 

What is the 2.5 mm Power Out Socket on the bottom of the Delkim TXi-D alarms for?

This socket is primarily designed to power illuminated visual indicators, such as the Delkim NiteLite or SmartLite Indication Sets. By drawing power directly from the alarm’s internal battery, it eliminates the need for Betalights (isotopes).

Crucially, on the TXi-D v2, this socket also serves as a data port: connecting the SmartLite hanger here is what unlocks the alarm’s ability to distinguish and signal drop-back bites.

 

Only the Response (R) and Volume (V) wheels are visible on the front of the Delkim TXi-D alarms. How do I adjust the tone?

In addition to the wheels, the TXi-D v2 features two push buttons on the front. Since the alarm is fully digital, you don’t adjust the tone via a dial.

Instead, you access the settings by switching the alarm on whilst holding down both push buttons. Once in ‘Set Up Mode’, you simply press the first button (PB1) to cycle through the 32 different tone frequencies until you find your preferred pitch.
