Just wondering if anyone else ever gets bumped by large fish sometimes ,while water detecting . I hunt the great lakes in Canada, last week in lake Erie about 4 ft. from shore I was almost knocked over after a very large fish hit my detector coil and my leg A guy walking his dog told me sturgeon hang out by shore in the spring Anyways it was an unforgettable experience .Still got 1 gold and 1 silver ring . .
