GeoSystems 3000 Meter Beltchain

---

Fieldchains contain a roll of cotton 3000m long which when tied onto a fence post, log, or any object, spools out behind you as you move turning a counter. Upon reaching a mark to be measured, just read the counter. You can then set the counter to zero and walk on or break the cotton and start again.

The GeoSystems Fieldchain measures in metres up to 9999. It is made from tough, high-impact plastic, and comes complete with a belt and spool of cotton.
