Side finding sonar?

[albinotrout]

The Humminbird 570 (I use the 565) has dual beam technology. Here is a screen shot from the Humminbird site for the 570. The dark fish marks are directly below the craft (transducer) and the white outlined fish marks are in the wider beam away from the craft. If you want color then the 586c, 587ci, and 596c are available in this series. The second pic shows how the dual beam works. Hope this helps!

Here is a link from the Humminbird site that gives the info on this. This might help you understand what the dual beam is. I know it is not Garmin but hey info is info. [cool]

Here is the info from Humminbird on the dual beam:

"dualbeam plus sonar

With DualBeam PLUS™ sonar, you have a narrowly focused center beam, surrounded by a second beam of 60º, expanding your coverage to an area equal your depth - in 20 feet of water, the wider beam covers an area 20 feet wide. The first beam is focused on the bottom, to show you structure, weeds and cover. The second beam is hunting for fish in the wide coverage area. You can sue the beam independently, yet working together, they give a you a clearer picture of what's going on underneath the boat. "



And a pic of the coverage area:
