Grade Control Products Aluminum GPS Rod, Two-Piece
The Grade Control Products GCP105 is a fixed-height, two-piece 2-meter GPS rod: the two 1-meter sections thread together into one solid length rather than telescoping, so there's no locking collar that can slip during use — a straightforward, foolproof setup that's popular with newer GPS operators and construction crews just getting into data collection. Its 5/8"-11 top thread is glued and pinned in place, so it won't back out or loosen over time. A 40-minute top-adjusting bubble vial — machined as a single aluminum piece with a high-contrast background — keeps the rod easy to level at a glance, and a titanium tip resists wear where the rod meets the ground. Built from 6061 aluminum alloy, it stands up to the bumps and drops of daily field use and breaks down to two 1-meter sections for transport.
Key Features
Fixed-height, thread-together design — no telescoping locking collar to slip during operational use, unlike a collapsible rover rod
Glued-and-pinned 5/8"-11 top thread — stays secure for the life of the rod instead of backing out under repeated attach/detach cycles
6061 aluminum alloy construction — stands up to bumps and drops in daily field use
Two-piece, 1-meter-section design — breaks down small for transport and reassembles with a simple screw joint
40-minute top-adjusting bubble vial — single-piece machined aluminum body with a high-contrast background for fast, accurate leveling
Titanium tip — resists wear at the point of ground contact for long-term accuracy
Standard 5/8"-11 top thread and 1.25 in. OD — the thread accepts GPS/GNSS receivers and prisms from any brand, while the OD fits standard bipods, data collector pole mounts, and UTV mounts that clamp onto the tube
Common Applications
RTK GNSS rover data collection
Construction layout and stakeout
Topographic and control surveying
Newer GPS operators who want a simple, no-slip setup over a telescoping rod
What's the difference between the GCP105 and the GCP104? Both share the same thread, tip, vial, and fixed-height two-piece design. The GCP104 is carbon fiber and lighter for long carry days; the GCP105 is 6061 aluminum, more impact-resistant, and priced lower.
