Forget, but dogs have something like 500,000 uh...whatever...level more smell sensitivity than humans. Bats fly using radar with out eyes. Trout fly up to my fly, then turn and swim away. My hooks come in contact with the magnet on the base of my vise. Hmmmmm...quite a difficult test to quantify...but wonder what would happen if I de-magnetized the hooks? Any thoughts?
