My Trimax Digital satellite finder  SM-4500 only used to set up my 1.3 prime focus KU band and 1.4 C band motor driven dishes.
 

Looks as new battery holds charge even when stored for some time as this model is noted for : )
 

Complete with case power supply instructions and box.
 

I no longer require it as I do not install dishes for a living.
Plus I find it easier to use a radio with Alanna at the TV end with the Technomate, as I know the signal levels to expect on that receiver.
 

It has a spectrum Analyzer plus blind scan it will also will show the picture from the received channel with sound so a nice piece of equipment.

Insurance is included in the postage : )

High quality item not one of the cheaper models : )
 

 God Bless Allen and Alanna
