You can easily upgrade or retrofit existing systems. The NAVIKNOT 350E employs electromagnetic sensors while the NAVIKNOT 450D uses Doppler sensors. The NAVIKNOT 600 series all employ satellite sensors, with the NAVIKNOT 600SE also featuring an electromagnetic sensor, and the 600SD using a Doppler transducer, so allowing complete flexibility of choice.
