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 quick, reliable lap times displayed on your AiM MyChron or MXL dash instantly.
This transmitter should be positioned at the start/finish line for recording overall lap times. MXL, EVO, and MyChron Light TG users can add the Infrared Split Transmitter (Part No. MC-020) positioned at other points around the track for segment 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 7.2 AH Battery (Part No. 1124-002, sold separately). An external battery allows "high power" mode (for tracks up to 60 feet wide).
