Brand: AIM Sports
This is the same transmitter included with all AiM MyChron3 and MXL dash kits. Use with a MyChron Optic Receiver, (Part No. MC-019 or MC-213 for autos, or Part No. MC-010 for karts) for accurate lap times displayed on your AiM MyChron or MXL dash instantly.
The transmitter should be positioned at the start/finish line for recording overall lap times. This transmitter can run in "low power" mode (for tracks up to 30 feet wide) on 8 AA batteries. It also includes an external wiring harness for use with a larger external 12-volt battery such as our 12 Volt 7.5 AH Battery (Part No. 1168, sold separately). An external battery allows "high power" mode (for tracks up to 60 feet wide).
