Technical Specifications

Professional Installation Requirements

The 520-5MSD requires professional thru-hull installation with custom fairing or flat-bottom mounting. The bronze housing is supplied without a fairing block, allowing for custom installation tailored to specific hull configurations. Professional installation ensures optimal acoustic performance and watertight integrity.

Superior Sonar Performance

The dual-frequency design provides exceptional versatility: 50 kHz frequency with 46° beam angle offers wide-area coverage ideal for locating fish schools and large structures, while 200 kHz frequency with 10° beam angle delivers precise bottom detail and accurate fish arch definition for species identification.

Deep Water Capability

The 600-watt power output combined with bronze construction ensures reliable performance in challenging deep-water conditions. The high-power design penetrates water column interference and provides strong echo returns from significant depths.

Marine Bronze Durability

Bronze construction offers superior corrosion resistance compared to plastic alternatives, making this transducer ideal for commercial fishing applications and vessels operating in harsh marine environments. The bronze housing provides excellent acoustic properties while maintaining long-term durability.
