Who it suits
Is it right for you?
Great for
- Carp and specimen anglers who like to fine-tune their alarms. There’s loads of control over sound, speed and light, making it easy to build a setup that suits your eyes, ears and the swim.
- Anglers leaving rods fishing while sorting the bivvy or making a brew. The movement/security sensor gives a handy extra layer of reassurance alongside sensible rod and reel security.
Maybe skip if
- Occasional anglers wanting the cheapest reliable alarm. The TXi-D is a premium option, and you’ll be paying for a deep feature set that may never get used.
- Anyone committed to rechargeable batteries. Standard 9V PP3 batteries are the recommended power source, so this won’t suit a rechargeable-only routine.

Quick verdict
A cracking alarm with serious control
The Delkim TXi-D is a top-end bite alarm for anglers who like to fine-tune everything from tone and volume to beep speed, LED brightness and night mode.
It’s not the cheapest route into bite indication, and some of its extras will be overkill for a simple day ticket session. But if you want a compact, refined alarm with proper digital control and security features, it’s a bob-on bit of kit.

The compact build, clear indication and included moulded hard case give it a properly premium feel.
Digital tone control, beep-speed adjustment and adaptable LEDs offer a strong, flexible indication package.
It won’t catch fish for you, but clear, customisable indication can help you react promptly to a proper take.
The core job is straightforward, though the broad feature set may take a little time to set up to your liking.
It’s expensive compared with basic alarms, but the deep control and security extras justify more of the spend for regular users.

The full rundown
Everything you'll want to know about the Delkim TXi-D Digital Bite Alarm
The Delkim TXi-D sits firmly in the ‘proper bit of kit’ end of the bite alarm world. It’s compact, nicely equipped and aimed at anglers who want more than a basic box that bleeps when the line moves. If you’re fussy about tone, light and sensitivity to movement, this is the sort of alarm that gives you plenty to get your teeth into.
Straight away, the big selling point is control. You get 64 digital tone settings, so there’s no need to put up with a sound that grates after a long night. Add in patented beep-speed control and you can tune the alarm’s character to your own preference. Some like a sharp, urgent chirp. Others prefer something slower and less shouty. The TXi-D lets you choose.
The twin clear LEDs are another strong part of the package. Variable brightness means you can keep things subtle in darkness or make the indication easier to pick out in daylight. The day/night mode is dead handy when the light changes, while stealth LED mode is useful if you don’t fancy lighting up the whole swim every time the line gives a little twitch.
That matters on proper bite-time sessions. You might be watching the water, chatting quietly in the bivvy or sorting a rig in the margins when the rod tip starts doing something interesting. Clear indication gets your attention without turning the swim into a fairground. It’s a small thing, but neat visual feedback can make the difference between reacting promptly and missing a cheeky opportunity.
The TXi-D also includes an IMU movement/security sensor. In plain English, it can detect movement of the alarm, adding a security function when your rods are left in position. It’s not an excuse to wander off and leave expensive gear vulnerable, obviously, but it’s a useful bit of backup while you’re making a brew, sorting bait or dealing with another rod.
Physically, it’s a tidy little alarm. The approximate dimensions are 103 × 38 × 40 mm including the antenna, with the body around 93 mm high without it. At roughly 118g including the battery, it won’t weigh your buzzer bar down. It also comes with a moulded black TXi-D hard case, weighing around 37g, which is proper handy when the kit goes back in the carryall.
Power comes from one standard 9V PP3 battery per alarm. That’s a familiar setup and easy enough to manage, but rechargeable batteries aren’t recommended here. If your usual routine is charging everything before a session, you’ll need to keep a spare PP3 or two in the tackle box. Losing power halfway through a night is a daft way to spoil an otherwise cracking session.
There’s a NiteLite output socket too, giving you the option of adding compatible night-light functionality. That’ll appeal to anglers who like a gentle reference light over the rods rather than relying only on a headtorch. Used sensibly, it keeps things low-key and helps you keep an eye on the setup without a load of faff.
The main question is whether you need all this adjustment. For short coarse sessions or the odd day-ticket trip, a simpler alarm may do the job perfectly well. But for dedicated carp anglers, regular overnight sessions and anyone who enjoys getting every part of the setup just so, the TXi-D looks like a very capable, polished choice. It’s premium, yes, but the feature set is properly generous rather than padded out with fluff.

Our take
The angle
This is all about control. The TXi-D gives you a huge range of digital tone settings, patented beep-speed control, variable LED brightness and a stealth LED mode, so you can set it up exactly how you like.
The movement/security sensor is another useful touch, especially when your rods are left unattended for a brew or a quick wander. It won’t replace common sense and a solid bank setup, but it adds another layer of reassurance.
Closer look
A compact alarm with plenty going on
The TXi-D packs a lot into a small body. Its headline features are the 64 digital tone settings and patented beep-speed control, letting you get the sound exactly where you want it. That’s ideal if you fish long nights and don’t want the same harsh bleep drilling into your head every time the wind nudges the line.
The twin clear LEDs give you strong visual indication, while variable brightness, day/night mode and stealth LED mode help you keep the display suitable for the conditions. The NiteLite output socket adds another option for keeping track of the rods after dark.
It runs from a standard 9V PP3 battery and comes with a moulded black TXi-D hard case. The case is a worthwhile inclusion: chuck the alarm away safely instead of letting it rattle around with leads, swingers and bits of terminal tackle.
Worth knowing. Rechargeable batteries aren’t recommended for this alarm. Keep a spare standard 9V PP3 in the tackle box, especially for overnight sessions where the rods are staying out for hours.
Who it suits
Best for anglers who like control
This is aimed squarely at the angler who enjoys dialling in a setup. You can tailor the tone, beep speed and LED brightness to suit your swim, your eyesight and how much noise you want on the bank. It’s especially appealing for carp anglers fishing multi-rod setups and regular overnighters.
The movement/security sensor is useful when you’re not stood over the rods every second. Leave them sensibly secured while you make a brew or sort the bivvy, and the alarm provides another bit of reassurance if someone starts interfering.
It’s less compelling for a casual angler who just wants a basic audible signal. In that situation, plenty of cheaper alarms will cover the essentials without making you navigate a deeper feature set.
FAQs in full
The bits anglers usually want to know
No. At approximately 118g including the battery, it’s a relatively light unit. The compact shape also keeps the setup neat, which is useful when you’re trying to keep a rod pod tidy and stable.
Yes. Variable LED brightness and day/night mode are built in, with stealth LED mode available when you want a more discreet display. The NiteLite output socket gives you further night-time flexibility.
No. The IMU movement/security sensor is a helpful extra, not a substitute for keeping your rods and reels secure. Stay sensible on the bank, particularly on busy venues or when fishing a swim away from your gear.
Worth knowing. The TXi-D makes most sense as part of a considered alarm setup. Pair it with sensible rod security, reliable batteries and a tidy pod arrangement, and the extra controls become genuinely useful rather than just menu clutter.
