While retaining the full functionality of a classic Brunton, the Standard Transit offers the best low-angle strike and dip measurements, enhanced durability, and a sleek design. CNC machined from a nearly indestructible aluminum block with a hard-anodized finish that resists scratches. Other features include an updated needle with a NeFeB disk magnet that improves shock resistance and resists demagnetization over time; induction dampening makes for a quick-settling needle; a sapphire jewel bearing for smooth needle movement throughout the life of the instrument; a transparent sight on the mirror for shooting accurate bearings within 1/2°; short and long sights provide additional functionality and accuracy when shooting bearings; plus the internal components are sealed with an O-ring for improved water and dust resistance. Note: Brunton Transits are NOT designed for use underwater, but are protected from rain and humidity. A protective leather case is included and the belt attachment makes it easy to carry your Brunton Transit in the field.
