Finally, affordable timing gear that's fun to use!

LINKGATE SF WIRELESS SYSTEM

LinkGate MF is Microgate's affordable wireless solution, offering secure, digitally encoded radio transmission at distances up to 2km (approx 1.2 miles).

LINKGATE SF FEATURES:

Transmit Start signal only
Retransmit an unreceived signal repeatedly even after a long delay, simply by pressing the Repeat key
Guarantee maximum reliability and accuracy (better than +/- 4/1000 of a second) even when transmission disturbance is particularly severe, thanks to its exclusive high redundancy transmission code with error correction
Set the competitor number and transmit it automatically to the timer
Transmission range of up to 2 km for the 10mw model, and up to 9km for the 500mw model (results may vary depending on topography, ambient radio interference, etc)
Select from 128 different available transmission channels
System is homologated and does not require any special licences
