With Simrad’s recent update, their forward-looking sonar has become a valuable tool, in particular when used in conjunction with their structure scan. The FLS is giving us an indication of the bottom coming up 350 feet ahead of us.
Three minutes later and water depth has gone from 132 feet to 77 feet, and we still have useful data at 300 feet ahead. The upper left window shows Structure Scan in the down view. The Structure Scan is a record of what is directly under the boat or more properly under the transducer – wherever this is mounted. FLS is looking forward.
A couple of minutes later. Bottom has trended up. Range forward is dropping with the shallower depths, but is still useful at 250 feet.
Here is an extreme crop of the previous photo showing the chart detail, along with the Structure Sound down view.
The conditions are favorable, cool, relatively clear water, and virtually calm.
Is this a direct competitor for Furuno Searchlight Sonar? No. But at 1/20th the cost it is a useful tool.
