I used to be just as paranoid as some of you guys about the seals. About two years ago though I noticed that alot of my hookups were coming where they were. I see seals now and head right for em'. They are there for one reason, LUNCH!!! I use them just the same as I do the birds as a indicator of where the fish are. Seems to work for me. My 02.
Good luck and tight lines, Jeff
