The Northwest Instrument 20x Builders Series Auto-Level is a professional grade level which allows users to set up an accurate horizontal plane for projects such as fence building and foundation construction. This auto level has a 1/16-inch accuracy at 75 feet and has a working range up to 150 feet. To give clear images, it offers 20x magnification.
The NBL20 has a top mounted optical site which lets the construction professional quickly site the target and start taking measurements. With a large focus knob and a horizontal circle, this survey instrument can make quick adjustments while not losing the sight of the target. Plus, this auto level has a steel cage wire-hung compensator.
With a multi-layer coated lens, this survey tool creates superior image quality and readings. Also, it features continuous drive for the tangent knobs which enables the user to quickly orient the level without limitations. As an extra feature, it comes with a 5/8-11 tripod thread which fits most standard tripods. Plus, it offers an optional aluminum tripod and grade rod.
