Designed for both vehicle mounting and portable use, the SB-400 provides accurate altitude readings up to 16,000 feet in 100-foot increments, making it a reliable tool for navigation and outdoor travel.

The large, easy-to-read dial can be quickly calibrated to known elevations by simply adjusting the outer ring. Barometric pressure is displayed on the inner ring, measuring from 21 to 31 inches of mercury (Hg) to help monitor weather trends.

This model includes a mounting plate for secure installation in your vehicle, while the retaining ring allows for lanyard attachment when used on the go. The backplate features corner holes for screw mounting, or you can use hook-and-loop fasteners for a more flexible, removable setup.
