9 Inch works for me in the Big Lake (Michigan). Anything larger would be washed away with the wave action.

Purchased my machine with the 9" and have not desired to go larger, am very weight sensitive due to shoulder injury. I also prefer the smaller 9" when going into the water; a lot less wave motion when in the big lake. I would also like to see a 9"x5" for use in the rocks and woods..

I saw one detector where the coil top had been covered in reflective striping tape purchased from an automothive store...

I have never figured why all coils and covers are either black or white; not real good for hunting in the water. I see rubber coil bumpers listed on ebay in various colors. Has anyone seen/tried one of these
