I was skeptical at first. - Moultrie Feeders Feeder Hog Light

This light works very well. I hunt feral hogs at night here in south Florida. I usually hunt over bait. I use a night vision sight on my rifle. As you may know, night vision sights "eat" batteries. During the night time hunt, I would conserve my night vision scope batteries by keeping the sight turned off and then occasionally turning on the sight to see if there were any feral pigs at the bait. Even doing this, the batteries would still be depleted after a few hours.
Now I use this light as an "alert" system. I strap it to a tree or stake near the bait. When the pigs come in to feed, the light switches "on", thereby alerting me that pigs are at the bait.
The feral pigs do not seem to be bothered, too much, by this light and continue to feed on the bait. Too bad for them!
The batteries last a long time. I don't really know how long, because I haven't had to replace them yet. I have close to 20 hrs of use on this set of batteries.
