The digital satellite finder is microprocessor controlled, making it very reliable and accurate. Signal strength is presented graphically on the LCD display in form of thermometer-scale and in numbers (0-99). It can also present pitch tones (the higher tone the better signal) on a buzzer. The digital satfinder is very sensitive and can detect the weakest of signals, strong incoming signals (powerful satellite, big dishes) can easily be attenuated for better readout. Features: Mini size and light weight, really portable. Designed with a compass for easier and quicker tuning. LCD graphic display with LED backlit to show the satellite signal intensity. Connect to your LNB and receiver to the satellite finder to track the clearest setting for the satellite you wish to tune to. No external power or batteries required, power supplied from your satellite receiver. With buzzer and attenuation control function, easy user-friendly operation.
