It’s the sound that rips you from a deep sleep in the dead of night. That single, piercing bleep from your bite alarm that turns into a screaming one-toner, sending adrenaline coursing through your veins.
In that moment, everything comes down to trust. Trust in your rig, trust in your knots, and absolute, unwavering trust in the little black box on your bankstick that just told you the fish of a lifetime is tearing off with your bait.
Let’s be honest, though. Choosing that little black box has become a minefield.
The wall of bite alarms in any good tackle shop is a sea of blinking LEDs, complex-looking dials, and price tags that range from a round of pints to a small fortune. How do you know if you’re paying for genuinely useful features or just expensive gimmicks?
That’s exactly why we’ve put this guide together.
We’re cutting through the noise. First, we’re going to dive into a no-nonsense buyer’s guide, breaking down what really matters when you’re on the bank. Then, we’ll get into our top picks—the alarms we’ve personally put through their paces and trust to do the job, season after season.
So, whether you’re buying your first ever set or looking to upgrade your tried and tested, you’re in the right place.
Let’s get you properly sorted!

Decoding Bite Alarms: What a Good Set Really Needs
Let’s have a proper chat about bite alarms!
It’s easy to get blinded by fancy features and flashing lights, but at 3 a.m. in the driving rain, none of that matters if your alarms let you down.
Your alarms are your ears – and sometimes your eyes – on the bank. They’re arguably the most important piece of electronics you’ll own, so choosing the right set is a decision you want to get right first time.
Forget the marketing hype for a minute. This is what I look for after decades on the bank, from windswept gravel pits to snaggy little club waters.
1. The Absolute Non-Negotiables
These are the features that, for me, are not up for debate. If an alarm doesn’t have these ticked off, I’m not interested.
- Rock-Solid Reliability & Weatherproofing:
- Can it handle a proper British downpour? Look for fully sealed electronics and a solid casing (IPX ratings like IP66 are a good sign).
- I’ve had cheap bite alarms pack in from heavy condensation alone. Reliability is number one. You need to be 100% confident that a bleep means a fish, not a fault.
- Clear, Differentiated Indication:
- Adjustable Tone: Essential on busy lakes so you can tell a run on your rods from the fella in the next swim.
- Adjustable Sensitivity: This is crucial. On a windy day with a strong undertow, you’ll want to decrease sensitivity to avoid false bleeps. Fishing tight to snags for shy-biting fish? You’ll want to crank it right up to register the slightest movement.
- Drop-Back Indication: A game-changer. This gives you a different sound and/or light when a fish picks up your rig and swims towards you, creating a slack line. Without it, you might miss some very cagey bites.
2. The Receiver: Your Bivvy Lifeline
The best alarms in the world are useless if the signal doesn’t get to the receiver in your bivvy.
- Signal Strength & Range: It’s not about being 200 yards away from your rods. It’s about having a signal that won’t drop out when you’re tucked behind thick foliage or in a swim with a dodgy signal.
- Battery Life & Warning: The receiver should last for days, if not weeks, on a single set of batteries. A low-battery warning is an absolute must-have.
- Vibration Mode: Perfect for keeping quiet on the bank and not disturbing others, or for when you have the volume turned down low while you sleep.
3. The “Game-Changer” Features
Once the basics are covered, these are the features that separate a good alarm from a great one.
- Mute Function (One-Touch): The ability to press one button to silence the alarm for 30-60 seconds is invaluable. It lets you set your bobbins and get the line perfect after a cast without the alarm screaming at you and annoying everyone on the lake.
- Latching vs. Running LEDs: A good alarm will have two LEDs. One (the latching LED) stays lit for about 20 seconds after a bleep so you know which rod went off if you missed the initial indication. The other (the running LED) will only flash while the line is being pulled from the spool.
- Stealth/Covert Mode: Turns off all the lights on the alarm heads for anglers who want to be as discreet as possible.
A Final Word…
Before you get drawn in by things like colour-changing LEDs and bivvy light syncing (which are great, but are luxuries), make sure the core functionality is perfect.
My advice?
Invest in reliability first and foremost. A set of Delkims or Nevilles from 20 years ago still works perfectly because they were built to do one job flawlessly: tell you when you’ve got a fish on.
Modern alarms should be no different.
1. Delkim Txi-D V2 Bite Alarm
Let’s get one thing straight before we even start: when you’re talking about Delkims, you’re talking about a legacy.
For decades, the old Txi-Plus was the gold standard for bite indication, trusted by some of the best anglers in the country. That iconic Delkim “warble” is a sound that’s etched into the brain of every serious carp angler.
Vibration Sensing & Beep Speed
This is what makes a Delkim a Delkim. It doesn’t use a roller wheel like almost every other alarm; it uses a patented vibration sensing system.
- What it means on the bank: Instead of waiting for the line to move a roller, it’s sensing every tiny pluck, knock, and vibration coming straight down the line from the rig. For detecting liners and the most subtle of drop-back bites, it is absolutely second to none. The new digital processing in the V2 has made this even more refined. You can dial the sensitivity right down in weedy or windy conditions, but you still feel totally connected to what’s happening at the business end.
- Beep Speed Control: This is a classic Delkim feature, perfected here. It allows you to set the speed of the bleeps to match the sensitivity. On a high sensitivity setting, you can have it screaming on a single bleep for a liner, or you can set it so it only gives a one-toner on a proper take. It gives you an incredible level of control over the information the alarm is giving you.
The Bells & Whistles
The biggest update for the Txi-D V2 is bringing all the modern, quality-of-life features to the party, but they’ve done it with that classic Delkim focus on function.
Multi-Colour LEDs
This was a long time coming! For the first time, you can now choose your LED colour (Purple, Red, White, Blue, Green, or Yellow) on each individual head. It’s a simple press-and-hold job to change it, and the setting is saved.
One-Touch Mute
An absolute godsend. A quick press of the button silences the alarm for 30 seconds, giving you enough time to set your bobbin and get the line perfect without the whole lake hearing you. It automatically re-arms itself afterwards.
Day & Night Mode
A genuinely useful feature. You can pre-set two different LED brightness levels.
This means you can have them on a brighter setting for daytime use and then, with a simple button press, switch all your alarms to a dimmer, more discreet setting for the night. The night mode also has “NiteLite” glow, where the LEDs stay dimly lit constantly.
Stealth Mode
For the anglers who want to go completely under the radar, this mode deactivates the LEDs on the Txi-D head, with all indication coming through on your receiver instead.
The Rx-D V2 Receiver
You can’t talk about the Txi-D without mentioning its partner.
The Rx-D receiver is rock-solid. The range is immense – far more than you’ll ever legally need – but that power means it has a bulletproof signal in even the most difficult, overgrown swims.
All the settings on the head are perfectly replicated on the receiver; the colours match, the tone matches, and the drop-back indication is crystal clear.
The anti-theft function (where the receiver screams if an alarm is switched off or moved) is a nice touch for peace of mind.
Final Verdict
So, have they still got the magic? Absolutely.
The Txi-D V2 takes the legendary Delkim sensitivity and wraps it in a modern, user-friendly package packed with genuinely useful features. They’ve managed to simplify the controls while adding more customisation.
They are a serious investment, there’s no hiding that. But you’re not just buying a bite alarm; you’re buying decades of bite indication pedigree, now fully updated for the modern angler.
- Pros: Unrivalled vibration-based bite detection, legendary reliability, fully weatherproof, highly customisable, brilliant one-touch mute.
- Cons: Premium price tag, some traditionalists might miss the simplicity of the old analogue dials.
2. Nash Siren R4 Alarms
If Delkims are the heritage Land Rovers of the bite alarm world, then the Nash R4s are the modern, top-spec Teslas!
They are crammed with technology, but here’s the thing – it’s not tech for tech’s sake. Every single feature in the R4 has been designed by anglers, for anglers, to solve a real-world problem you’ve likely faced on the bank.
Nash has always been known for clever, outside-the-box thinking, and the R4 is the pinnacle of that philosophy. This isn’t just an alarm that goes “bleep”; it’s a smart device that actively filters out false information to leave you with only the bites that matter.
The “Problem Solver” Features
Forget standard sensitivity for a minute. The R4’s party trick is its ability to think for itself and eliminate the false indications that drive us all mad.
- Wave Sensing Mode: This is an absolute game-changer for anyone who fishes big, windswept pits. We’ve all been there: whitecaps rolling in, bobbins dancing up and down, and you’re getting constant single bleeps. The R4’s tech can differentiate between the rhythmic rocking of waves and a genuine bite, effectively filtering out the chatter so you only get alerted when a carp is involved. It works brilliantly.
- Drift Safeguard: Another incredibly clever function, this time for fishing in weedy conditions or on flowing water. If you get a slow, steady build-up of weed on your line that starts to pull your lead out of position (a “drift”), the R4 will give you a specific alert. This is something most alarms would just register as a slow take, but the R4 lets you know what’s really happening so you can reel in and clear the rig.
Speed Sensing
At its core, the R4 uses a traditional roller wheel, but with a modern twist.
Alongside standard sensitivity settings, it has “Speed Sensing,” which allows it to differentiate between a slow, cautious pickup and a full-blooded screamer, giving you a better audible picture of what kind of take you’re having.
Combined with the decreasing tone for drop-backs, you’re never in any doubt about what’s going on.
Built for the Modern European Angler
You can tell Nash designed this with big waters and boat work in mind.
Homecoming Mode
This is a feature you won’t realise you need until you use it. There’s a rear-facing LED that, when activated, provides a bright, visible reference point.
For anyone dropping rigs from a boat in the dark, it’s a lifesaver, giving you a perfect guiding light to navigate safely back to your swim.
Night Glo Integration
The R4s are designed to be a complete system.
They have a direct MMCX connection port that allows you to plug in the Nash Night Glo bobbins. This gives you a pulsing light on your bobbin that perfectly mimics the alarm head, creating a clean, cable-free, and super-visible setup.
Build & Design
They feel bomb-proof!
The soft-touch rubberised finish is grippy and looks the part, and the integrated, removable snag ears are a fantastic touch—much sleeker than bolt-on afterthoughts.
They are, as you’d expect at this price, 100% waterproof and have been built to withstand some serious abuse.
The Final Verdict
The Nash R4’s are an unashamedly modern, feature-rich alarm.
If you’re an angler who faces challenging conditions – big windy waters, weedy venues, rivers, or you do a lot of boat work – the intelligent sensing and practical features are genuinely groundbreaking.
It’s not trying to be a Delkim; it’s carving its own path as the “thinking angler’s alarm.” If you want a simple, no-frills alarm, this probably isn’t for you.
But if you want a sophisticated tool that can be fine-tuned to give you an incredible advantage in tough conditions, the R4 is arguably the most advanced bit of kit on the bank right now.
- Pros: Groundbreaking wave and drift sensing, brilliant Homecoming Mode for boat work, superb build quality, seamless integration with the Night Glo range.
- Cons: The sheer number of features can be a little overwhelming at first, premium price point.
