36: Sonar Basics for Fishing: Expert Tips from Navy Sonar Tech Steve Chamberlin

Jamie Propst Season 1 Episode 36

Most anglers buy a fish finder, mount the transducer, and hit the water thinking they’re set. But here’s the truth: if you don’t know how to actually read your sonar, you’re probably just looking at the bottom—and missing the fish swimming right beneath you.

In this episode, Jamie & Scott sit down with Navy-trained sonar expert Steve Chamberlin, who has over 30 years of experience turning sonar from “complicated electronics” into a powerful tool any angler can use. Steve explains the mistakes that keep anglers blind to fish, why cone angles and frequencies matter more than you realize, and how a few simple adjustments can instantly make your sonar clearer and more reliable.
