How it works

Four steps from field to record

No training needed. Switch it on outdoors, walk the boundary, and let the device do the arithmetic.

Step 1, open sky: switching the device on outdoors under a clear view of the sky
Step 2, walk or mark: walking the field boundary with the handheld device
Step 3, get results: area, boundary length and total land value
Step 4, save or export: the record saved on the device and exported as a CSV file

User reviews

What users say after measuring with it

Real estate agents, contractors, landowners and land managers on what they use it for.

  • Review from a real estate agent and land broker: it helps me give buyers a quick sense of the property before we bring in a surveyor.
  • Review from a property and land manager: I can check different sections of the property without carrying maps and measuring tools.
  • Review from a landscape contractor: I can estimate lawn and planting areas before I start quoting the job.
  • Review from a fence contractor: one walk around the property gives me a quick idea of how much fencing I will need.
  • Review from an agricultural contractor: knowing the field size ahead of time makes it easier to plan the job.
  • Review from a woodland owner: I use it to keep track of my routes and understand the size of different sections of the property.
  • Review from park and campground staff: I can quickly check trail distances and open areas while I am already out in the field.
  • Review from an orchard and vineyard owner: it helps me measure different blocks of the orchard without setting up extra equipment.
  • Review from a site supervisor: it gives me a quick field check before we move on to detailed site measurements.
  • Review from a land buyer and property owner: I wanted to understand the property myself before making a decision.

Good to know

Questions, answered

The things people ask before they buy - including the honest limits.

Does it work indoors, under trees or between tall buildings?

No. All three models need a clear, open view of the sky. Indoors, dense tree cover and tall buildings block the satellite signal, so switch the device on outdoors and give it a few minutes to lock on.

Is it waterproof?

SC08 is rated IP67, dust-tight and protected against temporary immersion. CM84 and NB88 are not waterproof - keep them away from water and rain, and store them dry.

Which satellite systems does each model use?

CM84 and NB88 track GPS, BeiDou, GLONASS and QZSS. SC08 tracks BDS, GPS, GLONASS and Galileo across 128 channels. Every model receives four systems at once, but the combination differs by model.

Can I measure a figure-eight route?

No. The walked path must not cross itself or the area result will be inaccurate. Continuous, non-crossing routes are fine, including irregular shapes such as woodland edges and curved field boundaries.

Which units does it support?

Area: square metres, square feet, acres and hectares. Length: metres, feet, kilometres and miles. Switch between them in the settings menu.

Can I get the data onto my computer?

Yes. Connect the device over USB - the computer sees it as a USB drive - then copy the CSV files across for your own records, spreadsheets or accounting.

What is the difference between CM84 and NB88?

CM84 measures area, distance and land value with nine keys, and is the model with a documented two-point straight-line distance. NB88 keeps all of that, then adds slope and height measurement with a built-in barometer, five measurement modes and twelve keys.

Why does slope measurement show no result?

Start at the bottom of the slope and walk to the top, and keep the horizontal distance between the two points longer than ten metres. Slope and height readings are for reference only and are not saved to a record.

What makes SC08 different from the two land meters?

SC08 is an outdoor navigator rather than a higher-grade land meter. It adds waypoint collection, P-Navi point navigation, T-Navi track-back, an electronic compass, multiple coordinate systems and IP67 sealing - useful when you are working somewhere with no path at all.
