Hook the Horizon · field tool
One chain.
The weakest supported link
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

Step 01 — the job
The job
Start with the job, not the gear. What you enter here re-orders which links and which risks surface first.
No exact locations are requested or stored. Everything stays in this browser.
Step 02 — fast path
Major components
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.

Where this goes next
Field Ops owns the active trip. Water → Species → Forage when needed → Presentation → Tackle → Knot when the connection is unresolved → Field Ops → Debrief. Rig Signal is an optional device/electronics validation sidecar, not a required stage. Context travels only when you follow a link, and coordinates are stripped in both directions. Tackle Link keeps a local receipt of packet metadata and field paths when a packet-carrying handoff is actually followed.
Knot Analyst
Which connection joins these materials and how that connection can fail
If the connection itself is still unresolved, Knot Analyst owns that decision rather than Tackle Link guessing a knot.
Field Ops Desk
Keep the active trip, carry confirmed context, and turn the day into learning
Return the confirmed system result to Field Ops so the active trip — and the later debrief — keeps the same context.
Rig Signal
Whether a device or electronics claim is supported by the evidence behind it
If part of this setup rests on a claim printed on a box — a drag figure, a depth rating, a sensitivity number — Rig Signal checks what evidence sits behind it. Nothing here waits on that answer.
