Have been playing with the settings on my depth finder and am pretty pleased with the results. But my question is, on the finder I have there is an option for ping speed. The settings are in a percent type reading. What is the benefit in a lower or higher ping speed? I have it all the way up right now and am pleased with how the graph as a whole, along with the other settings being where they are, is reading. But not sure what any benefits in increased or decreased ping speed would be. Thanks for any info, God bless all.
