MyLaps TranX 140 Rental Kart Transponder – Permanent Mount

The MyLaps TranX 140 is the standard permanent transponder for rental karting operations — wired directly to the kart, drawing power from the kart's electrical system, and transmitting a unique kart ID to the timing loop every time the kart passes over it. No batteries, no charging schedules, no transponders left on a shelf or going missing between sessions. Fit it once and it works every session without any ongoing management.

For a rental operation running back-to-back sessions all day, the permanently wired approach is the only practical transponder solution. Rechargeable transponders work well in a controlled race environment where drivers or mechanics manage their own equipment — in a rental environment where karts turn around in minutes and equipment accountability is limited, permanent wiring removes an entire category of operational headache.

No subscription required — the TranX 140 is a one-time hardware purchase that keeps working session after session without ongoing costs.
