For the 16 color palette, each color covers 1.5 dB signal range. For the 8 color palette, each color covers 3 dB signal range.

Interference filter

This filters the echo signal to reduce high-level, spiky interference, such as engine noise. Select to add filter.

Pulse length

This can be used to specify the length of the transmitted ultrasonic pulse. A short pulse length improves the display detail but contains less energy, therefore it does not penetrate as deeply into the water as a longer pulse.

There is a choice of Auto, Short, Medium or Long. The Auto setting is recommended.

Pulse power

This can be used to specify the power output of the transmitted ultrasonic pulse. Low power output conserves the boat’s battery and produces a clear display in shallow water.

There is a choice of Auto, Low, Medium or High. The Auto setting is recommended.
