decides.
Start with the job — the water, the fish, the flow, the landing problem — then work backward through rod, reel, line, leader, connection and presentation. Declared ratings govern. Heuristics stay labelled. Missing specifications stay unknown.
Local-first · no locations collected · educational evaluation only
River
Current load, precision, abrasion, landing in flow
Lake
Depth change, vegetation, wind, search vs static
Ocean · Inshore
Salt corrosion, tide, structure abrasion, stronger fish
Deep-sea · Offshore
Continuous drag, capacity, depth, big-game loads

The finding, why it matters, and the fix
Start with the water and the main line
Add water type and line strength, or load an example setup. The check waits until those two are in. Missing ratings stay blank — nothing is invented to fill them.
Next: load an example lake setup, or see a worked start.
- · Water type
- · Main line strength
- · Rod power or published line rating
- · Published max drag

Saving a check freezes the current job and chain so it can be replayed and compared later. The full ledger, the step-through walk and batch checking all live on the check page.
