Whether I’m cruising in my G3 in Canada searching for shallow-water weedbeds, weedlines or structure, or in my center consul boat in Florida looking for deeper grass-flats for Redfish, Snook and Spotted Sea Trout, I rely on my Raymarine HybridTouch with CHIRP DownVision to mark the bottom and give me all the details even at speeds over 25mph.
You can see in the screen-grab above that even cruising at higher speeds on-plane, Raymarine gives me a clear, detailed image of the bottom. In this case I was looking for eel grass growing just off the shallow-flat in Southwest Florida to target eating-size Sea Trout. With Raymarine I find the fish and spend more time catching them than looking for them!!
