Who it suits
Is it right for you?
Great for
- Overnight and high-value session anglers. The movement sensor, digital radio link and enhanced weather protection give you useful reassurance when the rods are fishing while you’re asleep or away from the sticks.
- Anglers who like to tune every detail. With 64 tones, beep-speed control, LED options and memorised preferences, you can get the alarms sounding and looking just how you like them.
Maybe skip if
- Beginners building a first alarm set. There’s a lot here, but the price and depth of adjustment may be overkill when a simpler alarm would do the job nicely.
- Anglers who prefer basic, loud indication. If you just want a straightforward beep and don’t care about digital radio or security functions, cheaper kit will likely feel less of a faff.

Quick verdict
Verdict
The Txi-D Black Edition is a premium alarm for anglers who want sharp indication, proper wireless control and extra peace of mind when rods are left fishing. It’s packed with useful features rather than daft gimmicks.
The price bracket won’t suit every angler, and Delkim’s style of indication isn’t everyone’s cup of tea. But if you want a refined, compact alarm with serious security features, this is bob on.

Compact construction, enhanced weather protection and a supplied hard case give it a properly premium feel on paper.
Digital processing, adjustable beep speed, digital radio and range testing provide precise, flexible indication.
Clear custom indication and movement security can help you react confidently, though no alarm catches fish by itself.
The controls offer loads of personalisation, but the number of settings means a little setup time and menu learning.
It’s expensive kit, but the wireless, security, case and customisation features make more sense for serious regular users.

The full rundown
Everything you'll want to know about the Delkim Txi-D Black Edition
The Delkim Txi-D Black Edition is aimed squarely at anglers who want more than a basic bleeper on the pod. It’s a compact, high-end alarm with digital signal processing, wireless connectivity and enough adjustment to keep the most particular angler happy. If you like your kit refined and properly sorted, this one has plenty going for it.
The Black Edition keeps the familiar Delkim approach to indication, but the clever stuff is under the bonnet. Digital processing helps manage the signal, while beep-speed control lets you tailor how movement is represented. A slow, steady pull can sound different from a proper screaming take, which is handy when you’re trying to read what’s happening at the end of the line.
You also get 64 digital tone settings. That’s a lot of choice, mate. You can go subtle for a quiet syndicate swim or pick something more obvious when the wind’s rattling the trees and you’re trying to keep tabs on three rods. Once you’ve found your favourite setup, the alarm memorises your preferences, so there’s less faff when you’re back on the bank next time.
The wireless side is a big part of the Txi-D’s appeal. Digital radio transmission is included, along with range testing, so you can check the link between the alarms and receiver before settling in. That’s dead handy when rods are spread across a wide swim, tucked around a corner or positioned down the margins rather than lined up neatly in front of you.
Security is another strong card. The built-in IMU movement sensor is designed to detect unwanted movement of the alarm, adding another layer of reassurance if you’re fishing overnight or popping away from the rods for a brew. It won’t replace common sense on the bank, of course, but it’s a useful feature on a premium alarm.
The physical design has been trimmed down by roughly 30% compared with previous models. That makes the Black Edition less bulky on a buzzer bar and a bit easier to live with when space in the carryall is already tighter than a clipped-up spod rod. Enhanced weather protection is included too, which is just what you want in our famously cheerful British weather.
Visually, the alarm has twin clear LEDs, plus a stealth LED mode for times when you don’t want the swim glowing like the promenade at Blackpool. There’s also a mute function, useful when you’re setting the rods, checking a rig or sorting a snaggy lead arrangement without broadcasting every little button press across the lake.
The NiteLite output socket adds compatibility with a NiteLite setup, while the supplied moulded hard case gives each alarm proper protection between sessions. That case is more than a nice extra when you’ve paid high-end money; it helps keep the alarm safe from rogue leads, wet net heads and the usual tackle-bag carnage.
Power comes from one 9V battery per alarm, and retailer listings include one free 9V battery with each alarm. Still, chuck a spare in the side pocket before a long campaign. The x3 package is the neat route for a three-rod setup, bringing three alarms, one receiver and three black TXI-D hard cases together in one hit.
So, who’s it for? Anglers who care about indication detail, wireless control and security will find plenty to like. It’s not the obvious bargain choice, and there’s a learning curve if you want to explore every setting. But for a serious setup where you want compact alarms, custom sounds and proper digital connectivity, the Txi-D Black Edition is a cracking bit of kit.

Our take
The angle
This is less about shouting louder than every other alarm and more about giving you loads of control over how a bite or liner is shown. Beep speed, tone and LED behaviour can all be tuned to suit your swim and your own ears.
The big draw is the complete package: digital signal processing, digital radio transmission, range testing and an IMU movement sensor. That makes it a particularly interesting choice for anglers fishing overnight, roaming predators or leaving a rod tucked into the margins while you’re close by.
Closer look
A small alarm with a lot going on
The Black Edition is approximately 30% smaller than earlier models, so it sits neatly on a buzzer bar without hogging the whole setup. Enhanced weather protection is welcome for exposed swims, while the moulded hard case keeps it tidy between sessions.
Indication is highly adjustable. Digital signal processing, beep-speed control and 64 digital tones let you set up something subtle or properly attention-grabbing. Twin clear LEDs, stealth LED mode and a mute function cover the visual and practical details.
Worth knowing. Each alarm runs on one 9V battery. The retailer package includes one free battery per alarm, but take a spare if you’re heading away for a few nights. Dead alarms and bite-time don’t mix.
Who it suits
Built for serious, switched-on setups
The Txi-D Black Edition makes most sense for anglers who fish overnight, use a receiver or want extra control over how liners and takes are shown. The digital radio link and range testing are particularly useful when your rods aren’t all sitting within arm’s reach.
The IMU movement sensor is another reason to look at this model for higher-value kit and longer sessions. It adds a layer of security when you’re in the bivvy, grabbing a brew or keeping an eye on another rod. For predator anglers, margins and snaggy areas can make that reassurance especially handy.
Worth knowing. If you only fish short day sessions and want a basic sounder, you may never use half the features. A simpler alarm could save you a fair few quid for hooks, bait or a cheeky new rig box.
FAQs in full
The bits you’ll want cleared up
Does it work with the matching receiver? Yes. The Txi-D uses digital radio transmission, and the x3 package includes one receiver for three alarms. Range testing lets you check the wireless connection around the swim before you settle down.
What’s the security feature? The IMU movement sensor detects movement of the alarm, giving you an extra warning if something interferes with the setup. Treat it as added peace of mind, not a substitute for sensible rod security and keeping valuable tackle close.
Worth knowing. The NiteLite output socket, memorised preferences and stealth LED mode are the sort of touches you appreciate more after a few sessions. They keep the setup quieter, quicker and less faffy when you’re sorting rods in the dark.
