Chirp and Imaging
Raymarine pro Capt. Kirk Fay out of Long Island, New York, and tournament and Simrad pro Mark Maus out of Sarasota, Florida, use chirp and imaging sonar to add even more data to their research. "With chirp, I'm able to go to 3,000 feet of water and actually see and ID a swordfish," says Maus, who uses NSO and NSS evo3 units with an Airmar B275 LHW transducer. The swords "make a long-looking mark on the screen."
