The narrow 20° beam provides excellent bottom detail and spots fish hidden in clutter. The wide-angle 60° beam scouts a large area for surveying fish in many directions and picking up large schools of fast-moving baitfish. 4,000 watts peak-to-peak power. Three soft-key preset buttons make operation easy. Also displays water temperature.
