Raymarine SS164 Stainless Steel Thru-Hull - 0° Tilted Element - 1KW f/CP370 Sounder

The Raymarine SS164 Stainless Steel Thru-Hull with 0° Tilted Element is a dedicated transducer designed for anglers and boaters who demand reliable fish-finding performance in freshwater and nearshore saltwater environments. Built for integration with Raymarine's CP370 sounder systems, this transducer delivers consistent bottom composition and target detection without the complexity of multi-frequency alternatives.

Whether you're precision jigging shallow structure, mapping spawning grounds, or navigating unfamiliar water, this thru-hull unit provides the straightforward, dependable sonar imaging that serious anglers rely on when conditions demand clarity. The SS164's dual-frequency 1KW output and 0° tilted installation angle optimize vertical beam projection through the hull, eliminating the dead zone directly beneath your vessel and capturing fish and structure detail from the boat straight down.

Machined from marine-grade stainless steel, the housing resists corrosion in salt spray and vibration-induced degradation common to fiberglass mounting, ensuring years of consistent performance. The thru-hull design eliminates the mounting complexity of transom or trolling motor brackets while providing superior signal stability—critical when distinguishing between thermoclines, baitfish clouds, and hard bottom at depth. Boaters operating Raymarine CP370 sounder systems will find the SS164 straightforward to commission: the transducer connects directly to the sounder's transducer.
