When I use a Side Imaging product am I missing critical information directly under my boat?

Updated February 09, 2026 16:42

The area directly beneath the boat that is not covered by the Side Imaging beam is very small (approximately 5 degrees to either side of vertical). The conventional down-looking (2D) sonar that is built into the Side Imaging transducer covers this area below the boat. Side Imaging–capable units also allow a split-screen view, enabling you to see both 2D sonar coverage and Side Imaging sonar simultaneously.

In some situations, the Side Imaging view may still be obstructed by a feature or fixture on the boat’s hull. To address these scenarios, please refer to the following article:
