The Mr+ features a weatherproof sealed case along with top quality digital circuitry. It also features Fox's unique D-Tec Sensing System, and CNC Machined Tru Run roller wheel, which is found on the company's top-end N-series of alarms. You will find a power out socket at the rear of the alarm, which allows illuminated swingers to be plugged whilst it also features low battery drain (requires 2 x AAA batteries), a Piezo speaker and adjustable volume control. Due to the built-in I-Com Transmitter Technology the Mr+ has its own dedicated receiver that too features a weatherproof sealed case and top quality digital circuitry along with low battery drain (takes 3 x AA batteries). This Mr+ Receiver is very easy to sync with the alarm heads and in testing has worked in range in excess of 200m, however, Fox never condone being this far away from your rods, but what this does mean is that you have a very strong signal strength should you have heavy foliage between yourself and your rods.
