If you've read my other posts regarding Gerards suggestion that the Cass Creek Big Horn was a good bit of kit then you may also of realised I just bought one from the USA.
Seems like a well made unit and the quality of sound is surprisingly very good and I had a chance to experiment with it last Wednesday. I was on gate duty for 6 hours while a team of pro shooters conducted a feral goat/deer shoot in the Onkaparinga Gorge CP. Basically I was one of the gate persons required to control public access to the park while guns were being used in the cull.
A boring duty that I couldn't leave to say the least, so I thought I'd take advantage of the trying out the Big Horn just to see what I could attract to my position on gate #15. It worked a treat and even rattled off a couple of images of the birds as well.....I used on and off for a 6 hour period by simply hanging it in a tree about 50 feet away.
In the time period it brought in quite a few varieties just by leaving it in one position and varying the playback calls....and this was mostly middle of the day time periods.
