From the makers of the most popular  chronograph comes an all-in-one unit which is unlike any other.
The new chronograph from Xcortech is able to combine a Mock Suppressor / BB Illuminating Tracer unit with a built in computer controlled sensor to measure muzzle velocity and rof. The sensor also includes other modes of use such as a BB counter, to count up or down for a quick heads up display of estimated remaining bbs , and a low bb warning. To top it off a built-in battery reader displays your AEG battery level in real time as well as gives a low charge warning to let you know it is time to change your battery.
All of the information coming from the Tracer/Chrono unit is transmitted to the BB Control System (modeled after a PEQ Box) wirelessly. The BB Control System is where the unit can be programmed as well as output the information to a digital display.
Also included is the programmable SCU unit which easily plugs in-line with your battery to enable the burst setting from 2-10 rounds / full auto. This unit is also what transmits your current battery level to the PEQ Box display as well as protect your gun/battery from voltage drops.
