The SatKing SK-3200 is digital satellite Finder specially designed for VAST satellite TV. Being MPEG 4 the unit has been pre-programmed with the VAST paraFinders pre-set making the Finder very easy to use. If the other Finders you find just say digital they are not MPEG4 so they will not last. Simply plug the unit in to the dish and use the signal level bars to align you dish and once the level bars go green and the signal beeper is sounding the dish is aligned correctly and you are on the correct satellite. Then plug the antenna cable into your vast receiver or Foxtel STB and it will scan the channels in for you. The unit has a built in high power battery so the unit does not need to be connected to the VAST receiver to be used. Unlike many other lower priced Finders on the market this Finder you can actually receive VAST transponders. Many other mid lower cost Finders you are actually just receive the signal from the MPEG2 format and this could end anytime rendering your Finder useless. Special Note: All VAST services are MPEG4, there are no VAST MPEG2 services. If you have Foxtel and think this Finder sounds perfect for you well it is, you can simply align your dish on the VAST settings or simply select TP 3 in the sat setting menu and the unit will receive the actual Foxtel signal.
