Echonautics ST87 series
Angled Element Low Profile Stainless Steel Transducers
CHIRP | Medium or High Frequency | 1KW
Transducer Overview
Featuring a rugged and corrosion-resistant stainless-steel housing, this tilted element thru hull delivers 1kW CHIRP performance for today’s top-end sonar systems. The low-profile design minimizes drag below the hull surface for better depth performance, target resolution and bottom detail over a range of boat speeds. This is the ultimate transducer option for a wide variety of sportfishing boats.
The ST87 Series is offered in 0°, 12° and 18° angled elements to accommodate different hull deadrise angles up to 24°. All three tilt options are offered in Medium Frequency CHIRP (85-135kHz) and High Frequency CHIRP (130-210kHz).
