Fox Micron MX
The Fox Micron alarm has to be one of the longest-serving alarms as I can remember them back in the '80s. Fox has added to the Micron range over the years, and they've bought out the Micron MX that can be paired up and used with a Micron MX Receiver.
The new Micron MX Alarms comes with a multicoloured LED. You can change the colour from Red, Orange, Green, Blue, Purple and White, so if you get fed up with the colour you have chosen, you can simply change it instead of having to buy another alarm.
The alarm also has multi-step sensitivity and a volume and tone adjustment dial. Fox has used a high-quality cone speaker, which makes you take notice when it sounds. In addition, they have used a Tru-Run roller wheel connected to a D-Tech Sensing System to pick up the most sensitive bites. It comes fitted with a power out socket to attach illuminated bite indicators. It is supplied with a hard case to protect them when they aren't in use.
2 x AAA batteries power these alarms.
