Who it suits
Is it right for you?
Great for
- Carp anglers who like to customise their alarms. There’s proper control over tone, beep speed, LED brightness and stealth operation, so you can set the kit up around your own fishing.
- Anglers wanting compact alarms with extra security features. The smaller body, movement sensor, digital range test and weather protection make for a tidy, reassuring setup on the bank.
Maybe skip if
- Occasional anglers after a basic alarm. You’ll be paying for a lot of control and digital features that may go unused on short, straightforward sessions.
- Anyone wanting rechargeable battery convenience. The alarm uses a 9V PP3 and rechargeable batteries aren’t recommended, so spare standard batteries need to be part of the kit bag.

Quick verdict
Verdict
The Delkim Txi-D Digital Alarm packs a serious amount of control into a notably compact body. DSP helps cut down false indications, while adjustable beep speed, 64 tone settings and day/night LED adjustment let you get the alarm sounding and looking just how you like it.
It’s a high-value bit of kit rather than a bargain-bin buy, but the feature set is properly strong. For carp and coarse anglers who want a neat, customisable alarm with security features and a hard case included, it’s a cracking choice. Just remember to carry spare 9V PP3 batteries.

Compact construction, enhanced weather protection and a supplied moulded hard case point to a well-considered alarm package.
DSP, adjustable beep speed, digital tones and a range-test function give you strong control over indication and communication.
Cleaner indication and flexible sound and light settings can help you respond confidently, though no alarm catches fish on its own.
The controls offer lots of adjustment and memorised preferences, although the depth of features takes a little more setting up than a basic alarm.
It’s not the cheap option, but the compact design, security features, case and broad digital control make the package compelling for regular anglers.

The full rundown
Everything you'll want to know about the Delkim Txi-D Digital Alarm
The Delkim Txi-D Digital Alarm is aimed at anglers who want more than a simple bleep-and-go setup. This is a compact digital alarm with a proper spread of controls, from tone and beep speed through to LED brightness and stealth operation. Handy stuff when your fishing runs from bright summer days to dark, chilly bite-time sessions.
The first thing that jumps out is the size. Delkim states that the alarm body is 30% smaller, so it should sit neatly on a buzz bar or pod without making the whole setup look like a telecoms mast. That matters when you’re fishing a tight swim, squeezing rods into the margins or trying to keep everything compact for a roving coarse session.
Inside, Digital Signal Processing is there to help reduce false indications. Nobody wants the rods chattering away because of a bit of tow, wind or general surface nonsense. It won’t remove every possible nuisance indication, but the idea is simple: give you a cleaner picture of what’s happening at the rig end, so you can concentrate on proper movement and those screaming takes.
The sound controls are especially useful. You get 64 digital tone settings, plus patented beep-speed control that can be adjusted to suit your preference. Want a sharper, faster sound? Prefer something deeper and less frantic? You’ve got room to set the alarm around your ears rather than accepting one factory noise and cracking on.
The twin clear LEDs bring a bit more flexibility at night. Various colour options are available, and the brightness can be adjusted for day or night use. That’s dead handy when a bright LED is lighting up half the swim, or when you need a clear visual indication without turning the bivvy into a nightclub.
There’s also a stealth LED mode for keeping things lower-key. That’ll appeal to anyone fishing pressured venues, stalking the margins or simply wanting less glow around the rods. Add the mute function and you can make adjustments without creating a load of unnecessary noise while everyone else is tucked up in their sleeping bags.
The digital radio includes a range-test function, which is a useful bit of peace of mind when the receiver is away from the rods. You can check the link around the swim before settling in, rather than finding out at the worst possible moment that a signal isn’t behaving as expected. The IMU security movement sensor adds another layer for anglers who don’t fancy leaving valuable kit completely unprotected.
Practical touches haven’t been forgotten. The Txi-D has enhanced weather protection, a NiteLite output socket and memory for user preferences, so your chosen settings don’t need rebuilding every time you pick up the alarms. It’s supplied with a moulded hard case as well, which is spot on for keeping the alarm protected during transport.
Power comes from a 9V PP3 battery, and rechargeable batteries aren’t recommended. That’s not a deal-breaker, but it does mean carrying a spare in the tackle bag. Overall, the Txi-D is a smart, compact alarm for anglers who enjoy fine control and want a tidy digital setup rather than something basic and a bit naff.

Our take
The angle
The big draw here is control. You can tailor tone, beep speed, LED brightness and stealth mode to suit bright days, dark nights or a low-key margin session.
That compact body is handy when your setup is tight, too. Add the digital radio range test, movement sensor and memory for user preferences, and this is an alarm aimed at anglers who like their tackle smart, tidy and properly dialled in.
A compact digital setup
Small body, plenty going on
The Txi-D is built around a compact alarm body, stated to be 30% smaller, but it still brings a generous set of controls. DSP helps reduce false indications, while the adjustable beep-speed control and 64 digital tones let you tune the sound to your liking. The twin clear LEDs can be set up with different colour options and day/night brightness adjustment.
For night fishing, stealth LED mode and mute are both useful touches. You can keep the swim less illuminated and make changes without a load of racket. The NiteLite output socket adds another bit of flexibility if you like a clear visual cue after dark.
Worth knowing. The Txi-D uses a 9V PP3 battery, and rechargeable batteries aren’t recommended. Keep a spare standard battery in the tackle box, especially for longer sessions.
Best on the bank
Made for anglers who like control
This alarm makes most sense for carp anglers and serious coarse anglers who want to personalise their setup. If you fish different venues, change from day sessions to overnight trips, or like your indication settings just so, there’s plenty here to get stuck into.
It also suits compact setups. The smaller body keeps things neat on a buzz bar, pod or bankstick, while the enhanced weather protection is reassuring when the forecast turns a bit grim. The movement sensor is useful if you need extra security around expensive tackle.
Worth knowing. A simple alarm will do the job if you only fish occasional short sessions. The Txi-D earns its keep when you’ll actually use the sound, light, mute, radio and security controls.
Quick answers
The bits anglers usually ask about
The digital radio has a range-test function, so you can check communication between the alarm and receiver around your swim. That’s useful before you settle down for a bite-time, particularly when the rods are spread out or the receiver is positioned in the bivvy.
User preferences are memorised, meaning your chosen settings can be retained rather than treated like a clean slate every time. The alarm also includes an IMU security movement sensor, adding a useful deterrent and alert feature around your rods.
Worth knowing. The supplied moulded hard case is more than a nice extra. Use it for transport and storage so the compact alarm body, controls and LEDs aren’t rattling around loose in the tackle bag.
