Thanks Dustydog, the app is fine if you have a smartphone but I don't! Like you, for years I've used a simple satellite finder that you plug between the LMB and the receiver but I live in France and with the changes to the Astra satellites I find that tuning in is becoming more difficult. I wanted something that would tell me which satellite I was tuning into.
Its LNB - low noise block.
I think DD is right. You can get a cheap smartphone for less than £50 and it doesn't have to have a phone connection. You can download the app using wi-fi and as long as the phone has a camera, GPS receiver, and a magnetometer (i.e. is compass capable) it will work. Equally you could buy a cheap tablet but again make sure it can do compass, GPS, and has a camera. Look at Huawei phones and LG or Lenovo tablets.
For UK readers who may be interested, EE are doing the Huawei Y550 at the moment on PAYG at £34.99 + £20 top-up. It has 4G and all of the other necessary bits for it to work with Satfinder. We were in Haguenau in NE Alcase last year and I'll be blowed if I could get a sat signal but many others on site didn't seem to be having any problems. I got out my (Huawei) phone and ran Satfinder and found the sat was much higher than I though and clear of the top of some nearby tall trees. A bit more perseverance and I had a good signal.
