Marina neighbour was bemoaning the loss of a brand new spinaker pole, during a regatta last year, ($1000 worth) in the boat club the other week. Told us whereabouts he'd lost it and asked if we could use the Humminbird to see if we could spot it. The look on his face when we showed him the printout the next week was priceless! (said item is on the right, on the edge of the rocky ridge.)
