A flasher sonar device includes a flasher that produces light output pulses along a flasher ring display based upon sonar returns. A user interface selects between a normal mode and a zoom mode. When the normal mode is selected, a controller drives the flasher to display a normal range. When the zoom mode is selected, the controller divides the normal range into a first range and a second range, compresses the first range into a compressed range, enlarges the second range into an enlarged range, and drives the flasher to display the enlarged range interleaved with the compressed range.

Flasher sonar device with interleaved zoom

A sonar device includes a light source, a rotatable element, a motor for rotating the rotatable element, and a display. A light guide mounted on the rotatable element has an inlet end aligned with the light source and an outlet end aligned with the display. Light emitted from the light source enters the inlet end of the light guide, is directed from the inlet end to the outlet end in a beam, and is emitted out the outlet end of the light guide.
