The Spin Pro series offers advanced programming features, such as To "Auto-timing" and the direct programming of the batteryvoltage to all accu types and battery requirements. Furthermore, an additional transfer of real telemetry functions on the Jeti Duplex system is possible (engine RPM, battery voltage, temperature control, fault diagnosis). Note: no Duplex EX telemetry, i.e. display of these values "only" in the JetiBox mode of the JETI Duplex DC/DS transmitters and the JetiBox Profi. Tecnic
