Capt. Terry Nugent of Riptide Charters out of Cape Cod, Massachusetts, captured a series of remarkable screen shots, using his Raymarine CP570 chirp sonar module with an Airmar R599 transducer, CP100 chirp module and Raymarine’s DownVision.
Nugent, a longtime New England charter guide and angler, captioned each image with a description of the bait and predators, based on his experience. One image features large sandeels being eaten by mackerel, with a school of large striped bass waiting on the dropoff. The Chirp unit’s high-definition target separation even shows — in one image — a striped bass inside a bait ball.
