I have been known to hook two snares together when I didn't have an extension cable with me to be able to reach a post as an anchor, I don't like anything shorter than an eight-foot snare, for the way that I set mine. You can have 16 feet or cable but still only have 8 feet of useable snare cable depending on how you make the set. They make earth anchors as well, but I don't tend to like them due to the large variety of ground that I encounter, rocky, sandy, gumbo and sometimes good sandy loam, frozen ground of all types is hard to deal with then when it thaws out what was onetime hard fastened and immobile pulls out readily.
