Zones and accuracy
Last updated:
Hirro places each asset in a zone of your site, such as Row B, the wash bay or the workshop, and does not report positions in metres. A zone your team knows gets someone to the right place. Once they are there, the radar in the phone app shows how close the tag is and guides them to it.
How accurate is Hirro?
Section titled “How accurate is Hirro?”Hirro is accurate to the zone. In the field test on a Belgian rental and crane yard in October 2026, each asset was placed in a zone of the yard and then found with the radar. Draw zones at the size your team searches in: a row, a rack, a bay.
Why zones and not coordinates?
Section titled “Why zones and not coordinates?”A Bluetooth position in metres sounds precise but shifts as phones move and signals bounce off steel. A named zone is stable and matches how people talk on a yard: “it is in Row B” is an instruction someone can follow. The radar covers the last metres.
How does the radar work?
Section titled “How does the radar work?”Open the asset in the phone app and start the finder. The app reads the signal strength of the asset’s tag and shows whether you are getting closer. Walk until the signal is strongest. See Phone app.
How should I draw zones?
Section titled “How should I draw zones?”| Do | Avoid |
|---|---|
| Use names the team already says | Numbered zones nobody uses |
| Draw one zone per row, rack or bay | One zone for the whole yard |
| Give each stage its own zone: wash bay, workshop, ready line | Mixing stages in one zone |
| Redraw when the yard layout changes | Leaving old zones in place |
