Learn the controls ashore
Read the device manual and practice changing the main settings before a trip. Understand what the display is intended to represent and which parts are interpretation. Save a simple setup you can return to. Excessive adjustment while moving can distract from other boats, hazards and the crew. A screen should support observation rather than absorb all of your attention.
Confirm rather than assume
A mark on a display is not a species identification or a guarantee of a bite. Compare repeated observations and note uncertainty in your log. Keep equipment installation and power arrangements within the maker’s instructions. Carry appropriate independent navigation information for the outing, especially if electronic equipment fails. Learning a few functions thoroughly is often more useful than enabling every available overlay on the first visit.
