Hey, to each their own. Different strokes for different folks. I record my logs anywhere I go. That might be Houma, Hopedale, Chalmette, Venice, LA as well as Alabama, FL, GA, and SC waters. Having good charts is an awesome tool. Being able to self educate yourself on how to read contour lines and use them in comparison with your sonar and down / side scan is awesome.I have recently been targeting areas in SC for cobia, bull reds, etc... and have been focusing hard on areas I have done sonar logs on with my Nav. Platinum+ Cards. It really tightens everything up for me and gives me a more accurate area that I should be focusing on. 90% of the fish live in 10% of the water, right? Better be getting that 10% dialed in. I have been focusing in on the tight contour lines that represent steep drops and rises that funnel into holes or humps. Paying off for sure!
