I had my SAT system so thumbs times aligned and Pii for SD channels on Astra 19.2 hats loose enough. Now I'm almost finally arrived in the 20th century. And unfortunately had to find that some of the HD + channels (Pro7, SAT1, Kabel eins) will not work ("No Signal"). Various entries in relevant forums indicated a insufficiently aligned SAT dish. So forth with the Satfinder. I have the bowl must twist a few millimeters, and immediately had a massively better level. Thanks to the beeper in the SAT Finder you have to adjust when the plant is not permanently fixed at the screen, very useful if you just rumturnt rooftop :-) HD + channels now work all without problems. So for fine-tuning the device is well suited. To find the satellite itself (which could suggest the product description) is nothing. Of course, the device does not indicate which satellite you anpeilt straight. The rough alignment so you need to do differently.
