Who it suits
Is it right for you?
Great for
- Carp anglers running a Delkim and Rx-D setup. It slots neatly into that ecosystem and gives you plenty of control across day sessions, night fishing and remote monitoring.
- Predator anglers who want precise visual and audible indication. The adjustable response, tone and LED settings help you tune the alarm around the swim and the way you’re fishing.
Maybe skip if
- Anglers on a tight budget. A single alarm at £144.99 can make building a full set properly expensive.
- Anyone wanting a dead-simple alarm. There are plenty of menus and settings here, so it’s more involved than a basic one-button unit.

Introducing the Delkim Txi-D v2 Bite Alarm

- Piezo vibration sensing technology for bite indication.

Quick verdict
Verdict
The Delkim Txi-D v2 is a premium bite alarm with plenty going on behind its tidy little case. The piezo vibration sensing is the headline feature, while the twin 3 mm LEDs, 32 tones and adjustable response give you loads of control over how a take sounds and looks.
At £144.99 for one alarm, it’s not cheap, mate. But if you want a refined, weatherproof alarm that can be properly personalised and linked to an Rx-D receiver, it’s a cracking bit of kit for serious sessions.

Weatherproof construction, UK manufacture and a well-developed feature set give it a properly premium feel.
Piezo vibration sensing plus adjustable response and beep speed should suit a wide range of rigs and swims.
Clear, tuneable indication can help you react confidently to subtle movement, drop-backs and full runs.
The controls are useful, but 32 tones and multiple modes mean there’s more to learn than on a basic alarm.
£144.99 is steep for one alarm, though the receiver compatibility and breadth of features soften the sting.

The full rundown
Everything you'll want to know about the Delkim Txi-D v2 Bite Alarm
If you’re after a proper premium alarm rather than a noisy box that simply shouts ‘you’ve got a bite’, the Delkim Txi-D v2 is right in the mix. It’s compact, feature-packed and aimed at anglers who like their setup dialled in. No faffy gimmicks for the sake of it either — most of the controls have a job on the bank.
The big selling point is Delkim’s piezo vibration sensing technology. Instead of relying purely on a conventional roller wheel, the alarm reads vibration through the line and rod setup. That gives you a different style of indication, particularly useful when you’re fishing tight to a feature, laying a line carefully through the margins or using a slack-line approach where you want movement picked up without going completely mad.
For carp fishing, that flexibility can be proper handy. You might want a sharper response when the fish are on the munch, then a calmer setting when tow, wind or a twitchy liner is making the rods chatter. The Txi-D v2 gives you adjustable response and beep-speed controls, so you can tailor the alarm to the swim instead of putting up with one fixed personality.
It’s equally useful when you’re doing a bit of predator work and need to keep an eye on a static bait. A slow, cautious take from a pike or another predator doesn’t always look like a screaming run. Being able to tune the response, listen for a tone you’ll recognise and keep the visual indication clear can make the whole setup less stressful, especially when you’re juggling more than one rod.
The visual side is strong too. You get twin high-visibility 3 mm LEDs, with six colours to choose from: purple, red, white, blue, green and yellow. Pick one colour for each rod, match the alarms to your receiver, or just choose the shade that cuts through the gloom best. There are eight brightness levels as well, which matters when you’re fishing through the night and don’t want a tiny beacon blasting across the swim.
The day/night LED mode is a nice touch. You can keep a brighter daytime display, then switch to low-level night marking once the light drops. That means you can still glance over and see what’s happening without lighting up the whole bivvy like a fairground. And if you really want to keep things sneaky, stealth mode deactivates the LEDs during activation.
Sound-wise, 32 digital tone settings is a lot of choice. You can find something that cuts through wind, rain and a bit of bank-side nattering, then keep each alarm sounding different so you know which rod is away. Beep speed is adjustable too, giving you more information than a single generic bleep. It’s the sort of detail you appreciate when a take starts slowly and then turns into a proper screaming run.
The Txi-D v2 also works with the original Rx-D receiver and the newer Rx-D v2. That’s useful if you’re upgrading one alarm at a time rather than replacing an entire set. With a compatible receiver, the advanced anti-theft security alerts add another layer of reassurance when you’re tucked up in the bivvy or grabbing a quick brew away from the rods.
Power comes from a recommended high-quality 9 V PP3 battery, and continuous low-battery checking means you get warnings before things go properly pear-shaped. The 2.5 mm NiteLite output socket adds compatibility for a NiteLite setup, while the weatherproof synthetic-material construction is built for the damp, drizzle and general punishment that comes with UK fishing. At £144.99, it’s a high-value purchase rather than a bargain, but the feature set is seriously broad.

Our take
The angle
This isn’t just a basic ‘beep when the line moves’ alarm. The Txi-D v2 is built around vibration sensing, so it gives you a more tuneable way to pick up line movement, drop-backs and those proper savage takes. That makes it especially appealing when you’re fishing tight lines, slack lines or awkward margins where ordinary indication can get a bit hit-and-miss.
The big draw is control. You can set the tone, LED colour, brightness, response and beep speed to suit the swim, the light and your own hearing. Add stealth mode, night marking, low-battery warnings and anti-theft alerts, and it feels like an alarm designed for anglers who want to dial everything in rather than just switch it on and crack open the flask.
What you’re buying
A premium alarm with loads of control
The Txi-D v2 is a single Delkim alarm built around piezo vibration sensing. You get twin 3 mm LEDs, adjustable response and beep speed, 32 digital tones and eight brightness levels. That’s enough adjustment to make the alarm feel properly yours, whether you like a sharp, attention-grabbing setup or something more restrained.
The six LED colours are useful when running multiple rods. Give each alarm its own shade, or keep everything matching. The day/night mode and stealth setting are particularly welcome after dark, when bright LEDs can be a bit much in a quiet swim.
A 2.5 mm NiteLite output socket, continuous low-battery checking and weatherproof synthetic construction round out the practical stuff. It’s not just fancy menus; there are plenty of features that make a long session easier.
Worth knowing. The alarm is designed around a high-quality 9 V PP3 battery. Don’t skimp on the battery, mate — premium electronics deserve a decent power source, especially before a long night on the bank.
On the bank
Best for tuned-in setups
This is a strong fit for carp anglers already using Delkim kit, particularly anyone with an Rx-D or Rx-D v2 receiver. It also makes sense for anglers who fish a mix of tight lines, slack lines, margins and feature swims, where being able to change response and beep speed is more than just a nice extra.
Predator anglers can get plenty from it too. A static bait under a floatless setup can produce anything from a cautious pluck to a full-blooded run, and the adjustable indication gives you a better chance of understanding what’s happening before you lift into the fish.
Where it’s less convincing is for the casual angler who wants the cheapest route to a working alarm. You’re paying for refinement, compatibility and control. If you’ll never touch the tone, brightness or response settings, a simpler alarm may leave more quid in your pocket.
Quick answers
The bits anglers usually ask about
The Txi-D v2 works with both the original Rx-D receiver and the Rx-D v2. That’s useful for mixed or gradually upgraded setups, although you’ll need a compatible receiver to use the remote security features.
There are six LED colour choices and eight brightness levels, plus day/night mode and stealth mode. So you can keep visual indication clear in daylight, tone it down at night or switch the LEDs off during activation.
The alarm uses a recommended 9 V PP3 battery and continually checks its power level. It also has a 2.5 mm NiteLite output socket, adjustable response and beep speed, and 32 digital tone settings.
