In CT, the pot bouys are sometimes dragged underwater by the current. You caqn't see them until it's too late.
In my 20 plus years, I tangled one once, it csame off 1 mile later when I stopped and went into reverse.
I cut 3 lines with my "spurs" that I know of.
Yes we try to avoid them, however it is not always possible.
