FIRST RUN
Pick the question, not the tool.
The Field Kit is six small checks, not a sequence you have to finish. Open the one that answers the thing in front of you, keep the result if it matters, then go back to fishing.
NOTICE
Something changed.
What Changed? is for the moment the bite, water or behavior shifts and you need one sensible next test instead of five guesses.
TEST
Change one thing.
20-Cast Test keeps one variable moving and the rest still long enough to see whether the fish actually answered.
MEASURE
Replace the adjective.
Set the Drag, Drift Clock, Visibility Mark and Retrieve Pace turn vague words into something you can repeat later.
STOP
One useful answer is enough.
If the question has become a whole trip, a species problem, forage, tackle, knots or electronics, that is the point to hand it to the deeper application instead of stretching a quick instrument past its job.
