J.C., some guys like the Chamberlain and others use other devices. DoubleUp and I have had very good success with the Driveway Patrols. I really like them and they are cheap.
You need to determine the distance you will be shooting and then begin looking at a sensor that will work that far. DoubleUp uses his Driveway Patrol at 145 yards while I only use mine at 60 yards. But also, his sensor is modified with antennas to give a little range to it.
Weekender, nice photos, and no doubt some great hunts.
