Transducer angle requirements
The face of the transducer must be set to an appropriate angle.

A — For best results the transducer face should usually be angled so that it is parallel to the waterline whilst the vessel is underway.
B — Tilting the transducer down slightly may be required for best results on high speed vessels and vessels that run bow-high.
C — Tilting the transducer upwards is not recommended as this can cause aeration across the transducer face.
