I’ve been a passionate fisherman and boater throughout the Midwest region my entire life, so I’ve seen the technological advances in fish finders and fishing electronics over time. With better technology comes more complex installation protocols and steeper learning curves. Whether you’re using GPS to guide yourself out of a foggy cove on Kentucky Lake or looking for schools of “arches” on Lake Erie, fishing graphs and their components are a part of a boater’s toolkit more than ever.

I built this guide because modern marine tech has moved beyond simple depth finders—we are now dealing with integrated networking systems, forward-facing sonar, and more choices for battery configurations. Whether you’re trying to decide the difference between Lead Acid vs Lithium Batteries, and getting interference on your Mega Live crappie fishing at Lake of the Ozarks, you need experienced professionals who know how to wire these systems, and understand the specific Midwest nuances.
