FREE FIELD INSTRUMENT · RETURN MAP FIELD CHECK
WHAT MOVED?
You came back to familiar water and the old place stopped making sense. Don’t start by changing the lure. First sort out what stayed put from what moved.

One useful contrast
What this doesn’t prove
This is one comparison. The deck has the rest. It’s the Return Map idea in miniature: hang onto the physical thing that’s still there, find what changed, and don’t let one look prove more than it can.
The bigger water-reading guides stay free. Field Deck 04 — Reading One Water All Year is the version you carry and keep coming back to: 26 Return Map cards, the Return Record, a self-contained browser edition, and the Letter print set. See Field Deck 04 — $12 →
