Bosch Optical Level Kit GOL26CK 330 Foot 26X Automatic Surveyor Transit Set 1/16 In Accuracy Aluminum Tripod 8 Ft Grade Rod Plumb Bob IP54 Case

Bosch GOL26CK 26X Automatic Optical Surveyor Level Transit Kit

The Bosch GOL26CK is a 26x-power automatic optical level kit engineered to establish accurate site parameters, verify grading, and calculate horizontal distances over operating ranges up to 330 feet. Delivering a leveling accuracy of ±1/16 inch at 100 feet, this optical surveying instrument utilizes a large-aperture lens to maximize light gathering and project crisp targeting crosshairs over long spans. An internal magnetically dampened compensator stabilizes the line of sight against ambient ground vibrations, while an integrated mechanical transport lock protects the internal pendulum when stored inside the hard carrying case with the included aluminum tripod and 8-foot grade rod.

Best Used For:

• Commercial Site Grading & Foundation Layout: Establishing flat benchmarks, setting footings, and verifying site slope elevation across expansive construction zones.
• Utility Line & Drainage Pipe Alignment: Setting precise ditch pitch, verifying trench depth, and aligning curb lines along civil engineering projects.
• Topographic Mapping & Distance Estimation: Utilizing integrated horizontal, vertical, and stadia lines to calculate point-to-point distances and map terrain elevation changes.

Key Performance & Safety Features

• 26x Magnification Large-Aperture Lens: Gathers maximum ambient light to project crisp, high-resolution optical target views up to 330 feet.
• Magnetically Dampened Compensator: Rapidly stabilizes internal pendulum components to neutralize heavy machinery vibrations and soil shifts.
• Integrated Transport Protection Lock: Mechanical lock clamps the sensitive internal compensator mechanism during transport to protect factory calibration.
• Multi-Function Reticle Layout: Built-in crosshairs and stadia lines enable single-operator leveling, plumb checking, and optical distance estimation.
• Top-Mounted Quick-Sight Guide: Allows operators to execute fast initial targeting alignment on the leveling grade rod.
• 90-Degree Reflective Prism Bubble Vial: Features a circular bubble vial with a 90-degree mirror prism for effortless eye-level setup adjustments.
• IP54 Dust & Splash Water Protection: Die-cast aluminum base and composite overmolded housing resist harsh jobsite dust and water splashes.

Technical Specifications

Pro-Tip: Always engage the internal transport lock before placing the optical level into its case; locking the pendulum during transit protects the internal magnetic dampening system from heavy vibration and prevents calibration drift across active jobsite locations.
