Sokkia 724200 Economy 8.5 ft Dual Grad Knob-Lock Prism Pole

The Sokkia 724200 is an 8.5-foot dual graduation knob-lock prism pole built for survey crews and layout contractors who need a dependable, no-frills pole that performs accurately day after day. With standard 5/8x11 threading, dual foot/metric graduations, and a robust knob-lock clamping system, this pole integrates seamlessly into existing Sokkia setups and works with most aftermarket prism assemblies on the market. If your crew is running total station shots or GPS rover work across mixed-unit projects, the 724200 covers the bases without adding unnecessary cost.

Overview and Jobsite Applications

Designed as a practical field tool, the Sokkia 724200 suits a wide range of professional surveying and construction layout workflows. Its two-section telescoping design extends to 8.5 feet, giving crews adequate height for most standard traverse and stakeout operations while collapsing to a manageable carry length. The knob-lock mechanism provides a positive, repeatable lock that holds section height under the vibration and handling stress of daily field use. Whether you are running boundary surveys, road alignments, utility locates, or building layout, this pole gives rodmen a reliable platform to hold grade and keep measurements consistent across setups.

Key Specifications

• Model: Sokkia 724200
• Extended Length: 8.5 feet (approximately 2.6 meters)
• Sections: 2-section telescoping design
• Locking Mechanism: Knob-lock clamps
• Graduation System: Dual — feet/tenths and metric centimeters
• Thread Standard: 5/8-inch x 11 TPI (industry standard)
• Tip: Hardened steel point
• Construction: Lightweight fiberglass composite

Key Features

• Dual Graduation Marks: Feet-tenths on one side, metric centimeters on the other — keeps the pole compatible with projects operating in either unit system without switching equipment
• Knob-Lock Section Clamps: Positive locking clamps hold section height securely and release quickly for height adjustments in the field
• Standard 5/8x11 Threading: Accepts Sokkia prism assemblies and the vast majority of aftermarket prism mounts, tribrachs, and accessories from other major manufacturers
• Hardened Steel Tip: Resists wear on hard surfaces including concrete, asphalt, and rock — maintains a consistent point for accurate on-ground positioning
• Lightweight Fiberglass Construction: Reduces arm fatigue for rodmen holding pole during long occupation periods
• High-Visibility Graduation Markings: Clear, contrasting scale markings remain readable under direct sunlight and in low-light field conditions

Job Applications

Construction Layout: Use the 724200 to hold grade for building corners, column lines, and utility stakeout. The dual graduation system lets layout crews work directly in feet-tenths when the instrument is set in US units — no mental conversion required at the rod.

Boundary and Topographic Surveys: Licensed surveyors running boundary retracement or topo collection benefit from the pole's consistent height locking and readable scale when recording feature elevations and property corner positions.

GPS Rover Operations: The 5/8x11 thread accepts GPS rover brackets and bipods, making the 724200 a serviceable pole for RTK data collection workflows where crews move quickly between points.

Road and Utility Alignment: The 8.5-foot maximum extension covers most sightline requirements on road alignment and pipeline stakeout jobs where instrument height and terrain grade demand higher rod positions.

Frequently Asked Questions

What prisms are compatible with the Sokkia 724200 prism pole?

The 724200 uses the industry-standard 5/8-inch x 11 TPI thread, which is compatible with Sokkia prism assemblies as well as most aftermarket prism mounts from Leica, Seco, Crain, and other major manufacturers. If your existing prism assembly uses 5/8x11 threading, it will mount directly to this pole.

Does this pole work for GPS rover setups as well as total station work?

Yes. The standard 5/8x11 thread accepts GPS rover brackets, making this pole usable for RTK and static GPS workflows in addition to conventional total station and optical instrument setups. Verify your rover bracket thread before ordering if you are unsure of your antenna mount specification.

What is the collapsed length of the Sokkia 724200 for transport?

Sokkia does not publish an official collapsed length in their standard documentation for this model. Based on the two-section design and 8.5-foot extended length, typical collapsed length is approximately 5 to 5.5 feet. Contact Express Tools for confirmed measurements if transport clearance is a concern for your vehicle or storage setup.

Is the Sokkia 724200 suitable for high-precision survey work?

The 724200 is an economy-class pole intended for general surveying and construction layout where a solid, reliable platform is needed without premium pricing. For sub-centimeter control work or deformation monitoring requiring verified pole straightness certifications, a higher-grade carbon fiber or certified-tolerance pole may be more appropriate. For standard boundary, topo, and construction layout tolerances, this pole performs dependably.
