For a proper tool look no further that the SatLink 6906, brilliant self powered sat finder with built in 2.5" TV screen.
To be fair, using a Digital Angle finder, will do 50% of the work in finding the satellite, the sat finder will do the rest, as it will confirm that you have found the correct satellite.
Using both of the above takes all the guess work out of finding the satellite, and set up will be done in a matter of minutes.
