Through-hole probes: exploring the seabed with precision

The through-hull transducer is a crucial component of your marine electronics, providing a detailed view of the seabed for navigation, fishing, and safety. At Skysat, we rigorously select the highest-performing through-hull transducers, prioritizing reliability and data accuracy. Discover a complete range tailored to your specific needs, the result of our experience in offshore racing and our expertise in system integration.

choose the right probe technology

The choice of transducer technology is crucial to the quality of the information you receive. From traditional models to scanning transducers and CHIRP versions, each technology offers specific advantages. Understanding these differences is essential to optimizing your experience at sea.

Traditional probes: Reliable and proven, ideal for general use and good coverage.
CHIRP probes: Offer superior image resolution and better target separation, particularly effective for fishing.
Scanning probes (SideScan/DownScan): Allow detailed visualization of the seabed and submerged structures, useful for shipwreck searches or obstacle avoidance.
Multifunctional probes: Combine several technologies for maximum versatility.

installation and compatibility of through-hole probes

Proper installation and compatibility with your electronic system are essential to ensure the correct operation of your thru-hull transducer. Improper installation can impact performance and compromise data reliability. Consider the shape of your hull, the ideal location, and the communication protocols compatible with your multifunction display.

Deadrise angle: The angle of the hull influences the choice of probe and sometimes requires the use of adapter shims.
NMEA 2000/SeaTalk NG connectivity: Ensure compatibility with your onboard network for seamless data integration.
Materials: Choose a material compatible with your case (bronze, plastic, stainless steel) to avoid electrolytic corrosion.
Immersion depth: A probe that is too deep can generate turbulence and affect data quality.

factors influencing performance

Several factors can influence the performance of a through-hull transducer, including water quality, boat speed, and electrical noise. Understanding these factors will allow you to optimize your transducer settings and obtain accurate and reliable readings.

Turbulence and cavitation: Reducing speed in turbulent areas can improve image quality.
Gain and frequency settings: Adjust the parameters according to environmental conditions to optimize target detection.
Electrical interference: Check wiring and insulation to minimize electrical noise that can affect performance.
Water salinity and temperature: These factors can influence the propagation of sound waves and require adjustments to the probe parameters.

💡 Skysat's advice

Before installing your through-hole probe, perform a dry run to check for interference with other equipment and to optimize its placement. Feel free to contact us for personalized installation support.
