Buying Guide

What size should I choose? Select a plate that matches your transducer footprint (most common is 12″ by 3.5″). A thicker plate can add strength but may be heavier for small craft. What material matters? HDPE and marine-grade polymers resist saltwater, UV, and impact, with HDPE offering a clean finish that covers existing holes. Do I need pre-drilled holes? Pre-drilled plates speed installation; check hole alignment and use marine adhesive for a watertight seal. Is screwless mounting safer? Screwless options reduce hull penetration risk but require compatible transducers and mounting surfaces. How do I avoid hull damage? Prefer no-drill or no-new-holes solutions when possible and follow manufacturer adhesive guidelines to preserve hull integrity.
