We’ve had several questions about interpreting the sonar images. So we sent a couple of photos to our sonar guru, Steve Bradburn at Furuno, and asked him for a clarification.
Steve marked up our photo to show the correct interpretation.
And then sent the following comments.
Hi Steve:
It is kind of hard to explain. Sonars have a really difficult time giving accurate depth at shallow tilt angles because how the beam spreads and bounces away (instead of back to) the sonar. Also even in the bottom is pretty flat the sonar will show a rising bottom at the edge of the display.
