Perfect Vision birddog satellite signal meter for sale. This is the top of the line in signal locators. It can be set up to align everything from free to air satellite dishes, to Direct tv and Dish Network. This model can align Direct TV Swim satellites using the SWIM LNB's. Current setup is for Direct TV, but more satellite settings can be downloaded from the Perfect Vision web site, and installed into the meter using a typical printer usb cable (not included). Comes with the carrying case and electrical charge cord. This meter is only 6 months old. Never had a problem with the meter, and it works great. I no longer install Direct TV, and have no need for the meter. It also has very good battery life, depending on use. This meter sells for $600 new from most sites that sell perfect vision equipment, but I am selling it for $300.
