Airmar SS264 Transducer Pairs are used as pairs but sold separately!
Airmar has taken the proven B260 thru-hull and split it apart into a pair of tilted-element transducers. Called the SS264N air, these transducers are perfect for fast, center-console, and trailered sportfishing boats, or any vessel that cannot have a hru-hull with a High-Performance Fairing.
The narrow-beam broadband 200 kHz transducer will give you excellent resolution and crisp image detail needed for bottom fishing. The low ringing of this transducer is perfect for finding fish holding tight to the bottom and other structure.
