What Zoom Helps You See
Zoom narrows the display to the most important depth range. For panfish, that may be the bottom five feet or the suspended band where crappies are moving.
Sensitivity And Clutter
Use enough sensitivity to see your smallest jig, then reduce clutter until fish marks remain readable. Too much gain can hide the bite.
Use Reactions As Feedback
If fish rise and stall, change cadence. If they fade, downsize. If they never appear, move holes instead of staring at a blank screen.
