Shoot a mark with the phone already in your pocket.

A grade checker spends the day with a hand level in one hand and a tape in the other. Peep Sight puts a true level line across the phone camera, marks the phone at a fixed height so the tape has somewhere to sit, and tells you cut or fill by color, so you can read it out of the corner of your eye while you hold the tape.

On grade Fill: tip up to hit the mark Cut: tip down to hit the mark

Peep Sight replaces a hand level, not an instrument. After its two-shot level check, expect about 0.1°, roughly 0.1 ft at 50 ft. Use it for checks and pre-construction, not for staking.

What it does

Everything a hand level does, plus the read.

—

True level line

Drawn from the phone's tilt sensor and the camera's lens geometry, so it stays level across the whole view even when the phone rolls in your hand.

▸

Fixed tape notches

Big notches on both edges of the screen mark one fixed height on the phone. Set them at your tape mark and the lines move around them.

◉

Cut and fill at a glance

The whole screen edge glows green on grade, blue when the mark is low (fill), red when it's high (cut), and deepens past the band lines. A quick shake when it locks on.

%

Slope thumb wheel

Roll the wheel on the left edge to shoot a slope, plus or minus. The yellow target line follows it, a green line stays at true level, and a double-tap goes back to level.

+

Zoom wheel

Roll the bottom wheel to zoom on the crosshair for a mark a long way off. No pinching with one hand full of tape.

✓

Level check

Two reciprocal shots between two marks at the same height measure the phone's sensor error and correct it, the same check you'd run on a hand level.

How a shot works

Set. Hold. Aim. Read.

SET

Dial the grade

Leave the thumb wheel at 0% for a level shot, or roll in the slope you're checking.

HOLD

Phone on the tape

Put the side notches at your tape mark, say 5.00 ft above the hub.

AIM

Sight the stake

Bring the mark on the stake to the crosshair. Zoom in if it's far.

READ

Read the glow

Green is on grade. Blue means fill, red means cut, with the difference shown under the crosshair.

Next: distance to the mark

The native DirtWorks Field app will use the phone's depth sensor to measure the distance to whatever is under the crosshair.

DirtWorks Grade Checker

RTK grade checking against your Hive models, built into the DirtWorks Field app. The grade checker sees cut and fill against the finished-design surface at their boots, and the office sees every shot as it's taken.

◎

RTK against the model

Bring your own RTK receiver over a wireless connection. Check cut and fill against the same design surfaces the office keeps in Hive.

♪

Hands-free

Voice commands to take a shot or switch screens, and cut or fill read out loud, so your hands stay on the rod and the tape.

⇅

Live to Hive, no syncing

Every shot streams to Hive the moment it's taken. No end-of-day download, no file to forget.

↻

Office in the loop

Model updates push to the field in real time, and the checker chooses when to switch to the new model. The office watches shots land live.
