I confess, I have been doing the same thing as Shane, reading the emails and then not getting on here and posting. Rayburn can be picky and finicky for sure. A good si will help you find those brush piles. Just start scanning and have you a buoy marker ready, pop a way point, turn around, idle back by,drop a buoy and then use a 1 oz jig to confirm your finds. When I am search, I am not looking for bites, just piles that's all, as you do this, you will get more experienced with what a pile looks like and then will not need to test it.
What's up Shane, give me shout and lets catch up.
