Set your sluice wrong and you'll lose gold. Here's my quick field checklist to lock it in.

Quick Checklist

  • Angle: start ~1" drop per foot; adjust for material.
  • Flow: fast enough to clear blond sands, slow enough to hold black sand.
  • Feed: steady, classified, no fist-sized rocks.
  • Mats: aggressive for chunky, tighter for fines.

1) Angle (Start Point)

~1"/ft. If gold migrates, you're too steep. If it packs, too flat.

2) Flow You Want

Blond sands should "dance" out while black sands "sit." A pocket level helps: cheap and tough.

3) Mat Choices

Carry two: riffled mat + fine capture mat. Swap as pay changes. My go-to: field-tested mat.

4) Feed Discipline

Classify, feed small, check your first tray in 10 minutes, then lock settings.
