STAINLESS STEEL LOW-PROFILE THRU HU

This angled element series is offered in traditional CW (Continuous Wave) 600W dual frequency and 600W Medium/High Frequency CHIRP versions, all featuring a corrosion resistant and durable stainless-steel housing. The low profile thru-hull design minimizes drag below the hull surface while delivering superior target detail, structure resolution and bottom tracking performance - even when the boat is moving at speed. This makes it an ideal choice for a variety of high-performance fishing boats and all major sonar brands. All ST70 models are offered in versions with 0°, 12°, and 18° angled elements to accommodate various hull deadrise angles up to 24° with vertical beam orientation for superior performance. This includes three tilt options each for Medium Frequency CHIRP (80-130kHz), and High Frequency CHIRP (130-210kHz).
