Who it suits
Is it right for you?
Great for
- Carp anglers wanting compact alarms. It gives you proper bite indication and useful adjustment without taking over the pod.
- Anglers running multiple rods. Different LED colours make it quick to identify which rod has gone, especially in low light.
Maybe skip if
- Anglers wanting lots of sensitivity steps. There are only two sensitivity settings, so ultra-fine tuning isn’t its strong point.
- Anyone needing confirmed remote indication. This alarm’s listed features don’t include a receiver, so look at a compatible system if remote alerts are essential.

Introducing the Fox Mini Micron Multicolour
A compact Fox alarm with multicolour LEDs, drop-back detection and the sort of straightforward controls that make bite-time a lot less faffy.
- Model/manufacturer product ID: CEI225

Quick verdict
A little alarm with plenty going on
The Fox Mini Micron Multicolour is small, tidy and properly practical. You get adjustable volume, tone, sensitivity, LED intensity and a choice of four LED colours, so it’s easy to set up a pair or trio that suits your rods and your night vision.
It’s not the alarm for someone chasing loads of fancy receiver functions, but for clean, reliable bite indication on carp and coarse waters, it’s bob on. A cracking choice when you want the Fox name and useful features without sticking a massive brick on the bank.

The full rundown
Everything you'll want to know about the Fox Mini Micron Multicolour
There’s a lot to be said for an alarm that just gets on with it. No faffing through a maze of menus, no huge box clamped to the pod, and no need to learn a cockpit full of buttons before the rods are even clipped up. That’s where the Fox Mini Micron Multicolour comes in. It’s a compact alarm for carp and coarse anglers who want the basics done properly, with a few smart extras thrown in.
This is the Multicolour version of the Mini Micron, model CEI225. Its two 5 mm LEDs can show green, blue, red or orange, giving you an easy way to match each alarm to a rod. Sounds simple, and it is — but when you’re fishing three rods into different areas, a quick flash of colour can save you staring at the pod like a proper lemon.
The lights aren’t fixed at one brightness either. LED intensity is adjustable, which is handy across different situations. Keep them more noticeable for a daytime session or a long-range view, then tone them down when you’re tucked into the margins at night and don’t want the swim lit up like the Boxing Day sales.
Sound is covered with four volume settings and four tone settings. That gives you enough room to find a sound you can recognise without having it scream across the lake every time a tuft of weed brushes the line. A quieter setting is also much kinder when you’re sharing a bank with someone bivvied up ten yards away.
There are two sensitivity settings. That’s not the widest range around, so this isn’t aimed at anglers who want to micro-adjust every tiny movement. Still, for normal carp work, the choice is useful. You can keep things less twitchy when the wind is pushing a bit of bow into the line, then increase sensitivity when you’re fishing tight lines or watching for delicate activity.
The clever sensing comes from Fox’s D-Tec system and roller-wheel technology. In plain English, the alarm is designed to register line movement cleanly, while the roller wheel reads the run as it passes through. Add the drop-back differential and you’ve got a better chance of knowing whether a fish is heading away from you or has turned and come back towards the rig.
That drop-back feature matters more than some anglers reckon. A screaming take is obvious, bosh — you’re up and on it. A fish falling back towards the lead can be a different story, particularly if you’re fishing slack lines, soft margins or a rig where the initial movement is subtle. Clearer indication means less chance of sitting there while a bite turns into a blank.
On the physical side, the Mini Micron keeps things neat. Rubber rod-protecting inlays help cushion the rod blank, while the knurled locking collar gives you something grippy to tighten down when fingers are cold or wet. There’s also an on/off toggle switch, which is exactly the sort of simple control you’ll appreciate when packing up in the dark.
The alarm uses small N Type/LR1 batteries, so that’s one thing to remember before a night on the bank. They’re not the usual AA or AAA cells many anglers carry in a side pocket. You also get a 2.5 mm power-out socket, plus a piezo speaker for crisp sound. Overall, this is a tidy, compact Fox alarm with enough adjustment for proper day-to-day fishing, without making the setup a faff.

Our take
Why the Mini Micron still makes sense
The clever bit here isn’t one massive headline feature. It’s the combination of D-Tec sensing, roller-wheel technology, drop-back differentiation and proper control over the sound and lights. That makes it much more adaptable than its compact size suggests.
You can tone things down for a quiet margin swim, brighten the LEDs when you’re watching rods at range, or choose different colours across a set so you know exactly which rod has gone. Dead handy when three rods are clipped up to very different spots.
Small package · Useful controls
Closer look at the Mini Micron Multicolour
The Mini Micron Multicolour keeps the footprint small but doesn’t strip away the useful stuff. Two 5 mm LEDs, four colour choices, adjustable intensity, four volume levels and four tone settings give you plenty to play with. It’s easy to build a consistent colour system across your rods — say green for the margin, blue for the island and red for the open water.
The D-Tec sensing system and roller-wheel technology are geared towards clear line movement, while the drop-back differential gives extra information when a fish turns. Rubber inlays protect the rod, and the knurled collar helps hold everything neatly in place on the pod or bankstick.
Worth knowing. The two sensitivity settings are useful but fairly broad. If you love endlessly fine-tuning an alarm for every last liner, you may want a more adjustable model. For normal carp and coarse fishing, though, the control is refreshingly straightforward.
Rods off · Less faff
Who should buy it?
This is a strong fit for anglers who want a compact alarm from a familiar tackle brand, with proper visual and audible adjustment. It suits short day sessions, overnight carp trips and tidy three-rod setups where space on the pod matters.
It’s also handy for anglers who fish different venues through the year. Use a lower volume and softer LED glow on a quiet club lake, then turn things up when you’re on a bigger water and need to keep tabs on the rods from the bivvy.
Look elsewhere if remote indication is a must-have, or if you want loads of sensitivity steps and advanced alarm functions. The Mini Micron’s appeal is its clean, uncomplicated approach rather than a huge feature list.
Quick answers · Bank sense
FAQs in full
Yes. The four colour options make it easy to give each rod its own identity. That’s particularly useful at night or when the rods are spread across separate spots.
Yes. Its compact design, adjustable volume and adjustable LED intensity make it a sensible choice for close-range work, where a screaming alarm and blazing light can be a bit much.
Take spare N Type/LR1 batteries, and make sure the 2.5 mm power-out socket suits any accessory setup you plan to use. A quick check before leaving saves a daft bit of faff on the bank.

What anglers say
The word from the bank
Our read: a little alarm with plenty going on. The strongest reasons to choose it are compact and tidy on the bank without losing useful controls and four led colours and adjustable led intensity make rod identification easy; the main trade-off is only two sensitivity settings, so adjustment is less fine-grained than on pricier alarms.
