SE-200B SONAR ENGINE- 
Transducer(s) (One Thru-Hull or Two Transom mount) for both 90° Vertical and 90° Horizontal Scans

Each SE-200B Sonar Engine™ includes the "black-box" Engine, transducers, remote keypad and basic cabling as shown above. The SE-200B Sonar Engine™ scans a forward- looking beam both vertically and horizontally over a 90 degree segment using a single dual axis thru-hull transducer. In the vertical mode the beam scans from the surface ahead to the bottom below, similar to the graphic at left. This mode is particularly useful navigating unfamiliar waters, detecting coral, rock pinnacles and other submerged objects directly ahead of the vessel.
