The approach
Start with the right question.
Test depth changes, points, humps and transition edges while watching legal regulations.
In practice
Make it useful on the water.
Note whether catches came from moving baits, vertical approaches or live bait.
Keep learning
Connect the dots.
Use this guide as a starting point, then compare it with the water you're fishing, the tackle you're using, and your own observations. Good fishing knowledge grows through real practice.
