Who it suits
Is it right for you?
Great for
- Regular carp anglers. You get the control, security features and night-session functions to justify a more advanced alarm setup.
- Anglers who like fine adjustment. Tone choice, beep-speed control, LED colours, mute and vibration sensing let you set things up your way.
Maybe skip if
- Occasional day-ticket anglers. If you only need a simple alarm for the odd short session, much of the Txi-D’s feature set could sit unused.
- Anglers chasing the lowest possible spend. This is aimed at the premium end of the alarm market rather than bargain-bin tackle.

Introducing the Delkim Txi-D Alarm
The Delkim Txi-D brings Delkim’s vibration-sensing bite detection, digital radio system and loads of useful control into a compact alarm that’s built for serious carp and coarse anglers.
- Uses vibration sensing for bite detection, backed by patented Digital Signal Processing.
- Patented Beep Speed Control and 64 digital tone settings give plenty of adjustment.

Quick verdict
Verdict: a cracking alarm for anglers who like control
The Delkim Txi-D is a feature-packed alarm with a genuinely compact body, clever vibration sensing and loads of adjustment. The patented Digital Signal Processing and Beep Speed Control are the headline tech, but the day-to-day details matter too: selectable LED colours, mute, NiteLite output and a proper range-test function.
It’s not the cheapest route into bite indication, and the menu of settings may be more than a casual day-ticket angler needs. For regular carp anglers, night-session fans and anyone who likes their alarms dialled in just so, though, it’s a very polished bit of kit.

Enhanced weather protection, a compact design, an IMU security sensor and a moulded hard case give it a properly premium feel.
Vibration sensing, patented Digital Signal Processing, Beep Speed Control and a fully digital radio system make for a sophisticated package.
Clear indication, selectable tones, visual LEDs and night-session features can help you react confidently, though the alarm won’t replace good rigs and watercraft.
The controls offer plenty of flexibility, but 64 tones and the wider feature set mean there’s more to learn than with a basic alarm.
It’s a premium purchase, but the combination of sensing, security, digital range testing and compact design gives regular anglers plenty for their money.

The full rundown
Everything you'll want to know about the Delkim Txi-D Alarm
There’s something reassuring about a proper Delkim sitting on the buzzer bar. The Txi-D is the sort of alarm that looks compact and purposeful, then keeps throwing features at you once you start digging into the controls. It’s aimed squarely at anglers who want more than a basic beep when the line shifts.
The first thing you’ll notice is the size. This design is approximately 30% smaller than previous models, with the individual alarm measuring about 103mm high, 38mm wide and 40mm deep, excluding the antenna. At 118g including its battery, it won’t turn a compact pod into a lump of unnecessary tackle either.
Delkim has stuck with vibration sensing for bite detection, which is a big part of what gives the Txi-D its character. Rather than treating it like a conventional roller-wheel alarm, the system reads vibration at the alarm. That makes it particularly interesting for carp anglers fishing tight lines, margins or situations where you want a very responsive indication system.
The clever stuff continues with patented Digital Signal Processing. In plain English, that’s the bit helping the alarm interpret the signal it receives and turn it into a usable indication. Alongside it sits patented Beep Speed Control, so you can adjust how the alarm sounds rather than being stuck with one fixed rhythm.
There are 64 digital tone settings too. That’s more than enough to give every angler a favourite, whether you like a sharp, urgent note or something a little less shouty during a quiet night on the lake. Add selectable colours for the twin clear LEDs and you can make the setup feel properly personal.
The radio side is equally well sorted. The Txi-D uses a fully digital radio system and includes a range-test function, which is dead handy when you’re setting up on a new venue or fishing a swim where the rods and bivvy are a fair distance apart. Better to check the signal before bite-time than discover a problem when a proper lump is making off.
Security hasn’t been forgotten either. The built-in IMU security movement sensor is designed to detect movement of the alarm, adding another layer of protection when you’re tucked into the bivvy or grabbing a brew from the peg next door. It’s not a substitute for common sense, but it’s a welcome feature on a premium alarm.
For night work, the mute function and NiteLite output socket are both useful additions. Mute lets you sort the rods without broadcasting every little adjustment across the lake, while the NiteLite connection can make visual indication easier after dark. Those are the small touches that make a long session less of a faff.
Power comes from one 9V battery, such as a Duracell PP3. That’s easy enough to manage, but stick a spare in the tackle bag because a flat alarm battery is a proper mood-killer. The alarm also comes with enhanced weather protection and a moulded hard case, weighing 37g, which is a nice touch when the kit is rattling around in the barrow.
The honest take? The Txi-D is probably more alarm than a casual angler needs, but that’s hardly a criticism if you fish regularly. It gives you loads of control, a distinctive vibration-sensing system and useful security and night features, all in a neat body. If you like your rods, receiver and alarms working as one tidy setup, it’s a bob-on bit of kit.

Our take
Why the Txi-D stands out
The big difference is that the Txi-D uses vibration sensing for bite detection rather than relying solely on line movement across a traditional wheel. That gives the alarm a distinctive way of reading what’s happening at the rod tip, with patented Digital Signal Processing helping shape the signal it receives.
You also get a fully digital radio system with a range test, an IMU security movement sensor and 64 digital tone settings. That’s a serious amount of control in a body that’s approximately 30% smaller than previous models. It’s a tidy, modern alarm for anglers who want their setup to feel properly sorted.
A compact alarm with serious adjustment
What you’re buying
The Txi-D is an individual bite alarm built around vibration sensing. Its patented Digital Signal Processing and Beep Speed Control sit alongside 64 digital tone settings, so you can tune both the way it detects and the way it sounds to suit your fishing. The twin clear LEDs have selectable colours, making it easier to keep your setup consistent across the rods.
The fully digital radio system includes a range-test function, while the IMU security movement sensor adds protection when you’re not stood over the rods. A mute function, NiteLite output socket and enhanced weather protection make it well suited to proper overnight sessions, not just a quick few hours in the margins.
Worth knowing. The quoted 118g weight includes the battery but not the case. The alarm measures approximately 103mm high × 38mm wide × 40mm deep, excluding the antenna, and the moulded hard case weighs 37g.
Built for anglers who like control
A good fit for your fishing?
Regular carp anglers are the obvious audience. If your season involves overnight sessions, multiple rods and a receiver-based setup, the Txi-D gives you the control and security features to make the whole arrangement feel properly dialled in. The range test is especially useful when you’re spreading the kit around a large swim or fishing from a tucked-away bivvy.
It also suits anglers who enjoy fine-tuning their gear. Tone choice, beep-speed adjustment and selectable LED colours may sound like small things, but they’re handy when you spend plenty of time on the bank. The vibration-sensing approach will appeal to anyone who wants something a little different from a standard bite alarm.
Worth knowing. For short, occasional sessions, the Txi-D may be more involved than you need. If all you want is a basic alarm that shouts when the line moves, plenty of simpler options will do the job with less faff and less spend.
The quick answers
Everything else you need to know
Does it work with a receiver? The Txi-D has a fully digital radio system, so it’s designed to communicate digitally with a compatible Delkim receiver setup. Use the range-test function before settling in, particularly on a new venue or a swim with awkward bankside obstacles.
Is it suitable for night fishing? Yes. The mute function helps keep things quiet while you’re arranging the rods, the twin LEDs give clear visual indication, and the NiteLite output socket allows a compatible NiteLite connection. That’s a useful combination when the lake has gone properly black and you’re waiting for a bite-time move.
Worth knowing. The alarm takes one 9V battery, such as a Duracell PP3. Carry a spare, keep the case handy when packing down and use the range test as part of your setup routine rather than waiting for a screaming take to reveal a connection problem.
