Enhanced Image Quality (EIQ)
Enhanced Image Quality (EIQ) applications are intended for slower moving operations where the vehicle or vessel is moving slowly, or is stationary for at least a few seconds.
Description
The Fine EIQ applications overlap beams to improve image quality. EIQ uses four pings. EIQ - Fine uses eight pings. EIQ - Ultra Fine uses 12 pings. Note that the Fine EIQ applications have a slower sonar view refresh rate.
We recommend a maximum vessel speed of two knots for EIQ mode and 0.5 knots for EIQ - Fine mode.
