Full 360degree rotation for flexible viewing: a fully rotatable support rod lets you adjust to any viewing angle, ensuring the fish finder screen is clearly visible from anywhere on the boat while keeping the unit securely in place. Adjustable height range for flexible placement: quickrelease system enables effortless height adjustment from 42.6 cm to 65.6 cm (16.8' to 25.8'), accommodating different mounting setups and user preferences to position the screen at the eye level. Secure multihole mounting plate for broad compatibility: designed with general mounting patterns that fit most fish finder models; reinforced base plate provides exceptional stability and prevents unit movement even in rough waters. Use scenario: on a centerconsole boat, quickly adjust height and angle to maintain clear screen visibility while moving between casting and reeling positions. Use scenario: in rough seas or heavy chop, rely on the reinforced base plate and secure mounting to keep readings steady and the display steady.
