Willy Planinshek says the problem is that all of Barnstable County would have to do it because the seals and the sharks would just move to where the sonar isn’t.

Two Cape Cod residents say it would be safe and effective. Building a sonar barrier off the coast to ward off the seals-which is the food supply for the sharks, and that would deter shark attacks.
