Echonautics ST70H600

600W High Frequency CHIRP Transducer

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 0o,12o, and 18o angled elements to accommodate various hull deadrise angles up to 24o 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)

The CHIRP Advantage

Traditional marine echosounders operate at set frequencies (50 or 200kHz, for example) and transmit a short-duration pulse to display targets under the boat that can be identified by the specific frequency being used. CHIRP sonar (which stands for Compressed High Intensity Radar Pulse) emits a sweep pattern of many frequencies within a long-duration pulse. As a result, the sound energy delivered underwater is up to 1,000 times greater than conventional sonar — providing better deep-water penetration, improved fish detection and target separation, enhanced bottom detail and better sonar performance at higher vessel speeds. CHIRP sonar performance can be further enhanced by selecting a transducer style and CHIRP frequency range that best matches the vessel, water conditions, depths fished, and target species. For this reason, Echonautics offers a range of CHIRP transducers in Low, Medium, and High CHIRP frequency ranges. Our experts can help you find the ideal CHIRP transducer and frequency range to maximize your fishing success.

Tilt / Deadrise:

• 18° tilt version: for 16° to 24° hull deadrise
• 12° tilt version: for 8° to 15° hull deadrise
• 0° tilt version: for 0° to 7° hull deadrise

Mix and Match Adapter Cables

Echonautics transducers come with 8-meter/26-foot cables and standard 8-PIN Male connectors. One-meter/3.3-foot adapter cables are available through Echonautics.

• CBCCMS0501 Adapter Cable: Male 8-PIN black box connector (Seiwa, SI-TEX, Lorenz, JMC, Polar, MPS and JRC-Europe FF-901)
• CBCCMS0503 Adapter Cable: Female 8-PIN Garmin connector
• CBCCMS0502 Adapter Cable: Male 9-PIN Navico connector (Lowrance, Simrad, B&G)

These mix-and-match adapter cables make it simple to integrate high-performance Echonautics transducers with popular sonar systems from leading manufacturers.
