This is a Rechargeable Digital Satellite Finder with built-in LCD TV Screen, Buzzer and AV Out bought by my friend who is a part of my Satellite DXing team.
The tool has high sensitivity and has a MPEG4 DVB-S2 HD Tuner in it. Its as good as having a full-fledged TV along.
Infact proper TV using is not necessary at all and dish can be tuned during power failure too as it has a rechargeable Lithium battery working for 5 hours continuously.
We can watch and hear TV too on the 3.5 inch LCD screen.
