FIELD TOOL
What changed?
Pick the water you’re standing on and the thing that moved. You get what’s actually going on underneath it, the part almost everybody over-corrects, one test to run, and what each possible outcome means — including nothing at all, which counts as a result.
01
Where are you standing?

What changed?
None of this is a promise about your water on your day. It’s the reasoning with the work left showing, so you can argue with it once the fish give you something better.
This one needs JavaScript switched on. If you’d rather not, the same reasoning is written out longhand across the situation pages — start at What Happened?
It runs entirely in your browser. Nothing gets sent anywhere and nothing’s stored, so it keeps working after you’ve lost signal, which is usually right when you want it.
One test. Not four.
The instinct on a bad afternoon is to change lure, depth, speed and location all at once. Sometimes it even works, and it teaches you nothing, so you get to have the exact same afternoon again in three weeks.
Every card here gives you one move. Run it properly — twenty casts, not three — and then read the result off the table. A blank that kills a theory is worth more than a fish you can’t explain.
The coral band is the part worth reading twice. Most of the damage people do to a decent day comes from over-correcting: the water clouds up, so you change four things, when clouding up only changed one of them. Knowing what a change doesn’t do is what keeps you from throwing away a pattern that was still working fine.
What it doesn’t know
Your water. It has no idea what the temperature is, what got stocked, what the bait did last week, or whether somebody cleaned the place out yesterday afternoon. It won’t name a spot and it won’t name a lure, and any tool that offers to do either from a phone in your pocket is selling you something.
Sixteen changes, five kinds of water, and what’s going on under each one. That’s the whole thing, and it’s narrow on purpose. Once you can say why a change matters, the answer for your pond is yours to work out, and it’ll hold up better than anything somebody hands you.
If none of the sixteen fits, the entry you probably want is the last one, nothing changed and it died anyway. That’s most days, honestly. Past that, the long versions live in Common Situations, the same reasoning on cards you can carry with wet hands is in the shop, and how any of this gets decided before it goes up is on the record for anybody who wants to check the work.
