My honest thoughts are that Humminbird has and continues to lead the industry. They update there products every two years as need be and have only a handful of models to choose from. Unlike others that have a heavy selection of models and seem to update products every six months....
The Humminbird 360 is fantastic. Lowrance created the "spotlight scan" to compete with the 360 and it failed miserably. They can't even give them away. Now they have the "3D" which is another attempt to compete with the 360. If you want to play with your unit all day and move the screen around then get the Lowrance 3D. If you want to fish get a Humminbird 360.
Garmin...well they aren't even made in the USA just like Lowrance.
In a nut shell....Humminbird is Simply. Clearly. Better.
This is my opinion and solely my opinion but I have sold all brands (before going Humminbird exclusive) and Humminbird was always our top seller.
