Who it suits
Is it right for you?
Great for
- Predator anglers fishing static baits. The clear visual indication and dependable roller-wheel sensing make it easier to keep an eye on rods when bites can be subtle or the swim is spread out.
- Anglers building a premium multi-rod alarm setup. The RX+ receiver can sync with up to eight RX+ heads, while vibration alert and bivvy-light functions add useful extras after dark.
Maybe skip if
- Occasional anglers on a tight budget. You’ll pay for premium construction and the wider RX+ system, which may be overkill for a few short sessions.
- Anglers wanting the simplest possible audible alarm. There are cheaper, less feature-heavy options that’ll beep when the line moves without all the colour, receiver and setup options.
The lowdown

Quick verdict
A cracking alarm for serious sessions
The Fox RX+ is packed with the sort of details that make a long session easier: a sealed weatherproof case, proper line sensing, multi-colour LEDs and day or night modes. It feels like a premium bit of kit rather than a basic buzzer with a fancy badge.
The price bracket won’t suit every angler, especially if you only need a simple local alarm. But if dependable indication, neat rod protection and wireless receiver options matter, this is a very strong choice with plenty of useful fishing-friendly touches.

The sealed case, stainless-steel thread, rubber inlays and quality roller wheel all point to a properly finished alarm.
DTSS, the Tru-Run wheel and clear cone speaker give it a capable, refined indication package.
Better visibility and clearer alerts help you react promptly, especially when predator rods are spread across a swim.
Colour choices, day and night modes and the receiver make the setup straightforward once configured.
It offers plenty for the money, but the premium cost is harder to justify if you only need one basic alarm.

The full rundown
Everything you'll want to know about the Fox RX+ Bite Alarm
Fox has aimed the RX+ at anglers who want more than a basic alarm that shouts when something nudges the line. It’s a premium bite alarm with a proper list of useful bank-side details, rather than a load of daft bells and whistles for the sake of it.
For predator fishing, that matters. You might be watching more than one rod, fishing static baits at range or trying to keep tabs on a setup while the light fades. A clear visual signal and a dependable audible alert can save a lot of peering into the swim and wondering whether that was a bite, a liner or just a bit of tow.
The RX+ uses Fox’s D-Tec Plus Sensing System, or DTSS, to detect line movement. That sits alongside a CNC-machined Tru-Run roller wheel, giving the alarm a more refined sensing setup than the bog-standard wheel found on cheaper units. In plain English, it’s designed to keep indication smooth and consistent when the line starts to shift.
The twin multi-colour LEDs are another proper practical touch. You get red, green, blue, orange, purple and white to choose from. That’s handy when you want each rod to have its own colour, or when you simply prefer a particular shade in the dark. It also makes a quick glance at the alarm more useful when the rods are spread across a wide swim.
There are separate day and night operating modes too. That sounds like a small thing, but it’s exactly the sort of feature you appreciate at bite-time. You can have the display behaving sensibly for daylight and then switch to a more night-friendly setup without faffing around trying to shield bright LEDs with your hand.
Build quality is clearly a big part of the RX+ pitch. The case is weatherproof and sealed, so a wet night, cold mist or a proper miserable spell shouldn’t be a reason to pack away the electronics. It’s not an excuse to leave any tackle floating in a puddle, obviously, but the sealed design is reassuring when the forecast turns a bit grim.
The alarm mounts through a rigid 3/8-inch stainless-steel thread, giving you a sturdy connection to your banksticks or buzzer bars. Rod-friendly rubber inlays help protect the blank where it sits, which is a dead handy detail if you’re constantly moving rods, changing spots or tightening everything down for a hard take.
The speaker is a high-quality cone type, so audible indication should come through clearly without the alarm sounding tinny or cheap. For a static predator setup, that clean alert is useful when you’re sorting bait, making a brew or keeping watch from a bivvy. You still need to stay switched on, of course, but the RX+ is built to get your attention.
The wider system is where things get really interesting. Pair the heads with an RX+ receiver and you can sync up to eight alarms. The receiver also brings vibration alert and a bivvy-light function, giving you a quieter way to be alerted and a bit of illumination when you’re moving around camp. Presentation sets add rigid and soft compression washer options, plus a spare soft washer per unit, which makes setup across different bankware much less of a faff.
Power comes from two AA batteries in each RX+ alarm head, while the receiver takes three AA cells. That’s not unusual for a wireless setup, but it’s something to factor in before a longer campaign. Keep a spare set in the tackle bag and you’ll avoid the classic midnight battery drama. Overall, the RX+ is best seen as a premium, expandable system: excellent for anglers who’ll use its extra control and receiver features, a bit lavish for anyone after the cheapest route to a beep.

Our take
The clever bit is how little faff it adds
The RX+ isn’t just about making a racket when the line moves. Its D-Tec Plus Sensing System, Tru-Run roller wheel and clear colour options are all aimed at giving you cleaner, more useful information when the light goes, the weather turns or the rods are spread across a swim.
The kit
Closer look at what you’re buying
The RX+ alarm head combines digital circuitry with Fox’s D-Tec Plus Sensing System and a CNC-machined Tru-Run roller wheel. That’s the heart of the unit, giving it a polished way of detecting movement rather than relying on a basic, clunky setup. The weatherproof sealed case is equally important when you’re out in drizzle, mist or a full-on British soaking.
Twin multi-colour LEDs let you choose red, green, blue, orange, purple or white. Day and night operating modes help keep the display sensible as the light changes. Add the rigid 3/8-inch stainless-steel thread, rod-friendly rubber inlays and high-quality cone speaker, and it’s clear this is made to sit confidently on proper bankware.
Worth knowing. The RX+ head uses two AA batteries. The receiver uses three AA batteries. Presentation sets include rigid and soft compression washer options, plus a spare soft washer per unit, so check exactly what’s in the package you’re buying.
On the bank
Who it suits
This is a strong fit for predator anglers fishing static baits, multiple rods or swims where you can’t keep every tip under your nose. The colour choices make rod identification quick, while the receiver means you can keep an alert close by without standing over the rods all night. Vibration alert is particularly useful when you want a quieter heads-up.
It also suits anyone building a larger setup over time. The RX+ receiver can sync with up to eight RX+ heads, so you’re not boxed into a tiny two-rod system. That’s handy for anglers who fish different waters and want a flexible alarm setup that can grow with them.
Worth knowing. If your usual session is one rod, short duration and close range, the RX+ may be more alarm than you need. Its strength is the combination of premium construction, clear indication and expandable wireless control.
Quick answers
FAQs in full
Yes. The alarm offers red, green, blue, orange, purple and white LED colours, so you can give each rod its own visual identity or simply pick the shade you find easiest to see.
It has a weatherproof sealed case, which is exactly what you want when a session turns damp and miserable. As always, keep battery compartments and connectors looked after rather than deliberately dunking the unit.
The receiver can connect with up to eight RX+ heads and includes vibration alert plus a bivvy-light function. That makes it useful when you’re away from the rods, moving around camp or trying to keep alerts discreet.
