Delkim Txi-D Bite Alarm
Txi-D original and Txi-D v2
A compact wireless alarm with vibration sensing, loads of tone control and some genuinely useful security tricks. Here’s who the Delkim Txi-D suits on the bank.
- Patented vibration sensing and digital signal processing are designed to give clear, controlled bite indication.
- Built-in digital radio includes a range-test function for checking the connection before bite-time.
- An IMU movement sensor adds a security feature by detecting movement of the alarm.
- The original Txi-D offers 64 digital tones, while the Txi-D v2 has six LED colours and eight brightness levels.
Make sure it’s the right one. The name covers both the original Txi-D and the later Txi-D v2. The original has 64 tone settings; the v2 has 32 tones, six LED colours and eight brightness levels. Check the exact version before buying accessories or matching a receiver.

Who it suits
Is it right for you?
Great for
- Carp anglers who want a compact premium alarm. The small body, wireless radio and sharp control options suit a tidy three-rod setup or a mobile session where space matters.
- Anglers who like to fine-tune their presentation. Tone, volume-related control, LED options, mute and memory functions let you set the alarms up around your own fishing and swim.
Maybe skip if
- Beginners building a budget alarm set. You’re paying for refined sensing, wireless features and Delkim’s ecosystem, which may be more than you need for occasional overnighters.
- Anyone wanting rechargeable battery convenience. The Txi-D uses a 9V PP3 and rechargeable batteries aren’t recommended, so battery management needs a little thought.

Quick verdict
Verdict
The Delkim Txi-D is a premium, compact alarm for anglers who want sharp indication, proper wireless connectivity and loads of control without a massive brick hanging off the rod. Its vibration-sensing system and digital processing give it a distinctive, responsive feel.
It’s not the cheapest route into bite alarms, and the differences between the original and v2 can make listings a bit confusing. Get the version right and it’s a cracking choice for serious carp anglers, roving anglers and anyone who likes their setup neat, secure and properly dialled in.

Enhanced weather protection, a moulded hard case and a compact, carefully equipped build give it a properly premium feel.
Patented vibration sensing, digital signal processing and digital radio provide a sophisticated indication and wireless package.
Clear indication, adjustable sound and visual options help you respond confidently, though no alarm can replace sound watercraft and rig choice.
Mute, memory and range testing are genuinely handy, but the number of options and version differences can take a little getting used to.
It offers a lot for the money, but it remains a premium purchase and basic alarms will cover simpler fishing for considerably less.

The full rundown
Everything you'll want to know about the Delkim Txi-D Bite Alarm
There are bite alarms that simply go beep when the line moves, and then there are alarms that make you want to spend far too long fiddling with the settings before the first brew has even cooled down. The Delkim Txi-D sits firmly in the second camp. It’s a compact, feature-packed alarm aimed at anglers who want proper control on the bank, not just a noise when something’s had a wander.
The headline here is Delkim’s patented vibration sensing, backed up by digital signal processing. Rather than relying only on a conventional roller wheel, the alarm reads vibration through the line and turns that into bite indication. In practical terms, that’s designed to give you a responsive, distinctive system for fishing a range of setups, from tight lines to situations where subtle movement matters.
It’s also a notably small alarm. The Txi-D is 30% smaller than the previous models, which makes a difference when your buzz bar is already busy with swingers, snag ears and a receiver connection. It keeps the rods looking neat and doesn’t feel like you’ve bolted a chunky electronics box to the front of your pod. Dead handy for compact gear and mobile fishing.
The radio side is properly useful rather than just a box-ticking exercise. The Txi-D includes digital radio and a range-test function, so you can check the link between the alarm and receiver before settling into the swim. That’s a simple feature, but it’s bob on when you’ve moved the pod, changed the receiver position or are fishing a peg with plenty of bankside clutter.
Security gets a clever extra layer too. An IMU movement sensor is built into the alarm, giving it the ability to detect movement. That’s useful if you’re fishing close to the rods, taking a quick brew break or simply want more reassurance when the setup is unattended. It doesn’t replace common sense and a sensible rod position, but it’s a welcome bit of kit.
Visual indication is another strong point. The Txi-D uses twin clear, high-visibility LEDs, with variable brightness and a stealth LED mode. That gives you options for everything from a bright daytime setup to keeping the glow down at night when you don’t want your swim lit up like a landing strip. The v2 adds six selectable LED colours, while the original has its own control layout and feature set.
Sound-wise, there’s plenty of scope to make the alarm your own. The original Txi-D offers 64 digital tone settings, which is a frankly bonkers amount of choice. The Txi-D v2 uses 32 tones instead, along with eight LED-brightness levels. Both versions are aimed at anglers who like a particular sound and want their rods instantly recognisable when the lake suddenly goes bosh.
The practical touches are good as well. There’s a mute function for setting up without annoying the whole car park, memory for storing your preferences and a 2.5 mm NiteLite output socket for compatible night indication. The moulded hard case is a proper bonus too. It keeps the alarm protected in transit instead of letting it rattle around with leads, banksticks and half a packet of squashed biscuits.
There are a couple of things to keep in mind before you splash the cash. This is premium tackle, so it won’t make sense for every angler or every budget. You also need to know whether you’re buying the original Txi-D or the Txi-D v2, as their tone and LED options differ. Battery-wise, it takes one 9V PP3, and rechargeable batteries aren’t recommended. Get those details straight and the Txi-D is a very capable, very tidy alarm for serious sessions.

Our take
The angle
This is all about compact cleverness rather than gimmicks. The Txi-D packs vibration sensing, digital radio, movement security and memory for your settings into a body that’s 30% smaller than the previous model.
That makes it especially handy when you’re travelling light, fishing tight swims or don’t want bulky alarms dominating a minimalist setup.
Closer look
A little alarm with a lot going on
The Txi-D’s main trick is its patented vibration-sensing system, paired with digital signal processing. That gives it a different approach to bite indication from a basic roller alarm and suits anglers who want a responsive, controllable setup. The compact body is 30% smaller than previous models, so it sits neatly on a buzz bar without making the front of the pod look cluttered.
Digital radio is built in, with a range-test function for checking your alarm-to-receiver connection. There’s also an IMU movement sensor for added security, twin clear LEDs, variable brightness, stealth LED mode, mute and memory for your preferred settings. Add the 2.5 mm NiteLite socket and the supplied moulded hard case, and it’s a well-rounded bit of terminal electronics.
Worth knowing. Version details matter. The original Txi-D has 64 digital tone settings. The Txi-D v2 has 32 tones, six selectable LED colours and eight LED-brightness levels. If you’re matching alarms, a receiver or spare units, check the exact version rather than relying on a vague listing title.
Who it suits
Best on a tidy, serious setup
This alarm makes most sense for carp anglers who fish regularly and want more than a basic beep. It’s suited to a compact pod, snaggy margin work, overnight sessions and mobile fishing where a smaller alarm is easier to live with. The range test is handy when you’ve got the receiver back in the bivvy, while the movement sensor adds peace of mind when you’re a few steps away.
It also fits anglers who enjoy fine-tuning their kit. You can choose a tone that cuts through wind and bankside noise, adjust the LED presentation and use stealth mode when bright lights are a bit much. For a coarse-match angler who wants compact electronic indication around a busy setup, it’s neat and highly configurable, though the price may be harder to justify for occasional use.
Worth knowing. Keep a spare 9V PP3 in the tackle bag. The alarm uses one battery, and rechargeable batteries aren’t recommended. That’s a small bit of preparation that can save a very annoying session-start faff.
FAQs in full
The bits you’ll want clear before buying
Is it weather protected? Yes, the Txi-D includes enhanced weather protection for the usual mix of damp mornings, drizzle and splash around the swim. As with any electronic alarm, sensible storage still matters. The hard case is there for a reason, especially when the rods are packed away after a wet night.
Does it work with night indication? Yes. The 2.5 mm NiteLite output socket allows connection to a compatible NiteLite setup. The twin LEDs also provide high-visibility indication, with variable brightness and stealth LED mode. On the v2, you get six selectable LED colours and eight brightness levels.
Is the Txi-D overkill? For a casual angler who only wants a simple alarm, probably. For someone fishing regularly, relying on a receiver or wanting a compact premium setup, the extra control starts to make sense. You’re paying for the sensing system, wireless features, security options and refined controls rather than just the beep itself.
