When operating in the forward view, the transducer has an effective forward range of between five and eight times the depth of the water. For example, in 3 m (10 ft.) of water, the effective forward range is between 15 and 24 m (between 50 and 80 ft.). Water conditions and bottom conditions affect the actual range.

When operating in the downward view, the fore/aft range is equal to twice the depth of the water. For example, in 10 m (33 ft.) water depth, the screen will display 10 m (33 ft.) fore and 10 m (33 ft.) aft of the transducer. Deeper water provides a greater fore and aft range.
