I apologize for not updating this thread earlier. I did buy one of the FS1 meters for my son-in-law, a Bell installer. He says it works great and saves him a lot of time. However, he has not begun to play with all the features. He only needs to find one particular satellite quickly and reliably and could care less about anything else in the sky. He just uses it with a regular LNB to locate the one satellite. Once that satellite is found and dish angles set, the others fall into place anyway and he can swap the LNB for the quad version.
One unexpected (by us, anyway) benefit: he connects the meter to a hand-held dish to verify the site before installing anything whenever a customer wants the dish located in a dubious location. It's not so much for his own benefit -- he has enough experience to know when a tree line is in the way -- but to demonstrate to the customer that it won't work there. Some people won't take an installer's expert opinion, but can't argue the point when the meter tells them the same story!
Anyway, the upshot is the meter has paid for itself as he is on piecework, so the faster he can install a system the more he can do in a day and therefore the more money he makes. The other installers are jealous. So for his particular application, the FS1 was well worth the modest investment.
