Fox RX+ Micron – bite alarm with precise sensitivity adjustment
The Fox RX+ Micron is an electronic bite alarm for carp fishing that lets you tailor bite indication to the conditions on the water. Eight sensitivity settings and a false alarm elimination system help you distinguish genuine line movement from line rocking, while a distinct drop-back indication makes it easier to identify when a fish is moving towards you.
A sealed, weatherproof housing, day and night modes and compatibility with the RX+ receiver allow you to adapt to different fishing conditions. Deeper snag ears with rubber inserts cradle the rod without increasing the overall height of the alarm.
Key benefits and technologies
- D-Tec Plus Sensing System and Tru-Run wheel: digital circuitry, the DTSS sensing system and a CNC-machined roller wheel monitor line movement with eight sensitivity settings, from 2.8 to 90 mm.
- Intelligent Sensitivity and See-Saw: except at the highest sensitivity setting, the line must travel the set distance in one direction within two seconds. A change of direction resets the count, reducing false indications caused by line rocking.
- Colour Sync and Vari-Bright: choose from six colours for the two LEDs and adjust the brightness using three day and three night settings. In night mode, both LEDs glow softly in the selected colour, making it easier to locate your rod in the dark.
- Adjustable audible and wireless indication: eight volume levels, including a fully silent setting, eight tones and a cone speaker let you tailor the sound. Compatibility with the RX+ receiver and a range test function help you check the wireless connection at your swim.
- Built for bankside exposure: the sealed housing protects against the elements, while increased clearance around the roller wheel and improved drainage reduce the risk of freezing in extreme cold. A stainless steel thread provides secure mounting, while rubber inserts protect the rod's finish.

Frequently asked questions
Q: Is this a single alarm or a set with a receiver?
A: The Fox RX+ Micron, code CEI159, is a single bite alarm. It is compatible with the RX+ receiver, but this product is not a set with a receiver.
Q: How do I adjust the sensitivity when the line is rocking?
A: You can choose from eight line movement settings, from 2.8 to 90 mm. Except at the highest sensitivity setting, the system requires movement in one direction within two seconds, and a change of direction resets the count to reduce false indications.
Q: Can the alarm operate silently and power an illuminated Swinger?
A: Yes, the lowest of the eight volume levels is fully silent. A 2.5 mm power output socket is available to power an illuminated Swinger.
Q: Which batteries do you need, and how can you tell when they are running low?
A: Two AA batteries are required. When the battery voltage drops, the LEDs change colour to cyan so you can spot the warning in good time.
