Who it suits
Is it right for you?
Great for
- Txi-D users fishing larger venues. The long wireless range lets you keep an eye on the rods when you’re bivvied up, grabbing a brew or sorting kit elsewhere in the swim.
- Anglers who want extra security and alert control. The anti-theft system, DND, RunLite and last-activity recall give you more control than a basic receiver.
Maybe skip if
- Anglers using alarms from another system. This receiver is built for compatible Delkim Txi-D alarms, so it won’t be a sensible buy outside that setup.
- Short-session anglers who never leave the rods. If you’re always sat beside the buzzers, a receiver with this range and feature set could be more than you need.

Quick verdict
The verdict
If you’re running Delkim Txi-D alarms, the RX-D is a proper capable receiver. The range is more than enough for most venues, pairing is simple and the alert options are genuinely useful rather than just gimmicks.
It’s a premium bit of kit, mind. You’re paying for the Delkim ecosystem, security features and a refined alarm-to-receiver link. For serious carp anglers who like fishing away from the rods, it’s bob on.

The feature set, hard case and security focus give it a properly premium feel.
Long claimed range, signal replication and Boost mode make it capable across a wide range of swims.
It won’t catch fish directly, but reliable alerts and useful signal control can help you stay on top of bite-time.
Pairing is designed to be simple, and the controls cover practical bank situations without overcomplicating things.
It offers loads for the money, but the premium only really stacks up for anglers already invested in Txi-D alarms.

The full rundown
Everything you'll want to know about the Delkim RX-D Receiver
A receiver can be a proper game-changer when you’re fishing away from the rods. You might be tucked in the bivvy during a downpour, knocking up a brew at first light or having a quick wander to the far margin. The Delkim RX-D is built for exactly that sort of fishing, provided your alarms are compatible Txi-D models.
This is a digital radio receiver rather than a standalone alarm. It links with Delkim Txi-D alarms and mirrors what’s happening at the business end. You get the pulse and the visual signal, so a screaming take, a cautious drop-back or a little one-toner can still tell its own story away from the pod.
Range is the big headline. Delkim gives the standard maximum as up to 750 metres in clear line of sight. That’s a serious chunk of water, and comfortably more than most anglers will need on a normal lake. Real swims aren’t always a ruler-straight line, though. Trees, banks, buildings and a chunky bit of cover can all affect radio performance, so don’t treat the headline figure as a guaranteed fishing distance.
For tighter situations, the short-range setting works up to around 50 metres. That’s dead handy on smaller lakes, or when you’re fishing close to the rods and don’t want the receiver picking up more distance than necessary. It’s a sensible touch, rather than relying on one permanently wide-open range setting.
Then there’s Boost mode. This gives approximately 15% extra range for 15 minutes. That could be useful if you’ve walked further than planned, popped round to see a mate or need a bit more reach during a quick job away from the swim. It’s temporary, so you’re not hammering the battery or running maximum range all day for no reason.
The RX-D also brings some clever alert management. RunLite illuminates all seven receiver LEDs during an alert, making the unit easy to spot when the light’s poor. Adjustable vibro mode gives you a quieter way of getting notified, which is bang on when the whole lake seems asleep and you don’t fancy a receiver chirping across the swim.
DND mode is especially useful when you’re dealing with liners or fish brushing the line. It suppresses alerts until there’s approximately four seconds of continuous line movement, then automatically disengages after about 15 minutes. That means you can calm things down during a twitchy spell without forgetting you’ve left the receiver muted. Still, use it sensibly. If the fish are finicky and moving off slowly, any delay-based setting deserves a bit of thought.
Security is another big part of the RX-D’s appeal. Its advanced patented anti-theft security system is designed to give you extra peace of mind when you’re not sat right next to the gear. It doesn’t replace common sense — keep the rods and valuables secure — but it’s reassuring when you’re fishing a busy bank or sleeping between bite-times.
The last-activity recall is a handy little bank feature too. If you’ve missed an alert, or you wake up wondering which rod made a noise, the receiver can help you check what happened. Pairing with compatible Txi-D alarms is straightforward, and the supplied hard case is a proper bonus for protecting the unit in your carryall. With a lanyard and belt clip included, you can keep it close instead of leaving it balanced on a bivvy table. It runs from a 9 V PP3 battery, with some listings including one free battery, so you can get set up without an immediate dash to the tackle shop.

Our take
Why this receiver stands out
The RX-D isn’t just there to make a noise when a bobbin lifts. It mirrors the pulse and visual signals from your Txi-D alarms, gives you a stack of alert-control options and adds a proper anti-theft security system. That makes it especially handy on longer sessions, busy waters and swims where you can’t sit right behind the rods.
Closer look
A receiver made for keeping tabs on the rods
The RX-D receives digital signals from compatible Delkim Txi-D alarms and reproduces both their pulse and visual information. That matters because not every take is a full-blooded run. A slow pull, drop-back or stuttering take can give you different clues, and the receiver is designed to carry those signals away from the swim.
Its standard range reaches up to 750 metres in clear line of sight, while the short-range setting is aimed at distances up to approximately 50 metres. Boost mode adds around 15% extra range for 15 minutes, which is useful for a cheeky wander without committing to maximum output all session.
Worth knowing. Range figures are always at their happiest in clear line of sight. On the bank, trees, buildings, changing water levels and the layout of the venue can all reduce usable range. Think of 750 metres as the upper limit, not a promise that every swim will behave identically.
Who it suits
Best for anglers who fish away from the pod
This is a strong fit for Txi-D owners on larger pits, canals and waters where you might need to leave the rods for a few minutes. RunLite makes alerts easy to see, adjustable vibro gives you a discreet option and last-activity recall can help when you’ve missed exactly which rod kicked off.
DND is useful around nuisance liners and busy margins. It waits for approximately four seconds of continuous line movement before alerting, then disengages automatically after roughly 15 minutes. That can reduce faff, but don’t leave it switched on blindly if the fish are moving cautiously.
The anti-theft security system adds another layer of reassurance, especially when you’re sleeping or fishing a venue where you don’t want to be glued to the rods. It’s still a premium accessory, so the value is strongest when you’ll actually use the range and features.
FAQs in full
The bits anglers usually want to know
Pairing is intended to be easy with compatible Txi-D alarms. Once linked, the receiver follows the alarm signals, including the visual and pulse information. Make sure you’re buying for the Txi-D system rather than assuming it’ll work with every Delkim alarm.
The receiver uses a 9 V PP3 battery. Keep a spare in the tackle bag, particularly for longer sessions or colder weather. The moulded hard case is useful for stopping the receiver getting bashed about among leads, bait tubs and the rest of the usual van-load of kit.
It comes with a lanyard and attachments, including a belt clip, so you can keep it on you while moving around the swim. That sounds simple, but it’s exactly the sort of detail that stops the receiver being left on a chair while you’re halfway down the lake.

What anglers say
The word from the bank
Our read: the verdict. The strongest reasons to choose it are long standard range, with a short-range setting and temporary boost mode and replicates both the audible pulse and visual signal from compatible txi-d alarms; the main trade-off is only makes sense if you already use compatible txi-d alarms.
