In ALASKA, we can snare bears (and Squirrels). I have never used the SAC1000 that you pictured. We use this a bucket snare that is similar in that it holds the bears paw in a snare. The bear reaches into the bucket to get the bait, triggering the snare, the spring closes it and when the bear pulls back, the snare is in place holding the paw. The bucket is about 5-6 foot up attached to the side of a tree. The height will keep little bears or cubs from reaching into the bucket. Works well on wild bears and bears that are around humans. It is a great tool for problems bears near people or trashing you cabin. This is just one example of foot snaring. There are a few others that work too.

If you really want info. call AK Fish and Game Biologist for Unit 16. There is a predator control program where you can snare as many bears as you want. Some fight it, some don't. Most brown bears will be really mad and try to get justice when they see you. Most black bears will not try to attack while still tied to the tree. Some will if you let them go. Some you cannot let go unless darted by Fish and Game. The first year we had to let the brown bears go. We had to call Fish and Game and they met us out there and darted them so we could let them go. They changed that right away. Now you can snare brown bears. And the rules change each year. They change them to help us get the results they want. Not the other way around. The state uses us to manage the animals. You can get a permit to fly around and shoot wolves from the air. Why, because gas is so expensive, they let us do it for free and we pay them a fee to do the paperwork. Cost's them nothing, it's all on us if you want to do it. Get a plane, a lot of insurance, permit and paperwork, go fly around and get some. It's not as easy as it sounds either. Very expensive insurance besides the airplane your throwing around up there dodging trees while shooting at running targets. Not easy but a lot of fun.
Sorry we are full of people up here. We only let one of you in when one of you leaves first! Canada has lot's of room for people, try over there first.
If the first trappers that settled the west had some common sense rules to follow, that is how Alaska is for trapping. We don't have to have all the rules you do down there. You can still trap just like it was 100 years ago. You just have to follow some simple rules and use common sense when managing your trapline or animals. Back to bear snares......
