Shoot your bench, mark the BLACK LINE on the rod. Every reading in the app is inches UP or DOWN from that line — same as the Grade Shot Ledger.
Type any plan number (grade, rim, invert, TW/BW). Get the rod move from your black line.
BLACK SQUARES A–I are your magnet corners — the same letters you marked on the plan. Letters never change.
ADD YOUR OWN: tap any corner on the plan (building, wall, walk — anything) — the tap locks onto the exact plan coordinate — then hit MAKE THIS CORNER J. It joins the net with the next letter (orange-ringed square) and everything can pull from it. Tap it again to REMOVE if you change your mind.
1 · TAP anything — light, drain, wall corner, purple grade. The card says which two corners to pull from and the two tape numbers. Where the tapes cross is the mark. Pulls stay under 100' (under 90' when possible) with a good crossing angle; the map draws both pull lines.
2 · ORANGE DIAMONDS S1–S6 are stake points for the far stuff. Tap one — it tells you how to set that stake from the building (two tapes + a check tape). Drive it, ribbon it, then far features pull from stakes.
3 · GRADES: pick your zero (122.9 floor / 126.6 hot top / custom), shoot the bench, mark the black line. Cards + ROD button give inches UP/DOWN from the line. Subgrade chips (−6″ −8″ −12″…) for gravel checks.
4 · MEASURE chip: tap point-to-point for any distance. Tap a black corner square to get corner-to-corner check dims for your magnet net.
