SECO 5217-40-YEL Construction Series Thumb-Release Bipod

1) Website Listing Description

The SECO 5217-40-YEL Construction Series Thumb-Release Bipod is a professional field support solution designed to provide a stable, freestanding setup for GNSS/GPS antenna poles and prism poles. Built for demanding surveying and construction environments, this yellow Construction Series bipod combines fast field setup, independent leg adjustment, pole protection, and convenient transportation.

The No-Crush head is designed to help prevent damage to carbon-fiber range and prism poles, even when excessive clamping force is applied. Compatible poles measuring 1 to 1.25 inches (25.4 to 31.8 mm) outside diameter attach through the open clamp, while 1.5-inch (38.1 mm) OD poles can be loaded through the top.

Both legs adjust independently and extend to 6 feet (1.8 m), making it easier to establish a stable pole position on uneven or changing terrain. When the job is finished, the bipod collapses to 43 inches (109 cm) for transport and storage.

Weighing 4.25 lb (1.93 kg), the 5217-40-YEL offers a practical combination of stability and portability for daily field use. This model also includes a carrying bag and leg clip, making it easier to keep the bipod contained and organized while moving between jobsites.

For surveyors, contractors, engineers, and construction layout crews who regularly work with GNSS receivers, GPS antenna poles, prism poles, robotic total stations, and other compatible survey equipment, the SECO 5217-40-YEL provides a dependable solution for creating a stable freestanding pole setup.

4) Common Applications

GNSS and GPS Surveying
Use the 5217-40-YEL to establish a freestanding GNSS/GPS antenna or rover pole when a stable pole position is required during field measurements.

Prism Pole Support
Provides support for compatible prism poles used with conventional or robotic total stations.

Construction Layout
Useful for building layout, site layout, utility layout, anchor bolt positioning, structural layout, and other construction measurement tasks involving compatible prism or GNSS poles.

Robotic Total Station Work
Helps stabilize compatible prism pole configurations during robotic total station surveying and construction layout.

Topographic Surveying
Useful when collecting points across jobsites where a freestanding GNSS or prism pole can improve workflow.

Grade and Site Work
Independent leg adjustment makes the bipod practical for grading, earthwork, site development, roadway, and civil construction environments with uneven terrain.

Control and Engineering Surveying
Suitable for temporary pole support during control, engineering, as-built, and general field surveying operations.

Utility and Infrastructure Work
Useful for survey and construction crews performing utility location, infrastructure layout, roadway, site development, and similar field measurement work.

Multi-Brand Survey Equipment Configurations
The bipod may be suitable for pole configurations used with Leica, Trimble, Topcon, Sokkia, Spectra Precision, GeoMax, Carlson, CHCNAV, Stonex, Emlid, and other surveying equipment. Compatibility should be verified using the pole outside diameter and specific field configuration rather than brand name alone.
