You're looking at a used Brunton compass, which retails for $309.00. I've had this sitting around for several years after using it for field season doing geology. It is in perfect working condition. Mirror is scratch free and everything is as it appears. Here's the description from Brunton:
More traditional in design, the Conventional uses Alnico II magnets and
a "V" cut sapphire jewel bearing for smooth movement. Conventional
suspension offers premium performance when used within a balancing
region. Because the body is diecast aluminum, the Conventional is not
only accurate, but also durable.
- Includes Leather Transit Case
- Long Alnico II rare earth magnets for quick magnetic north needle alignment
- Azimuth accuracy ±1/2° with 1° graduations
- Magnetic declination adjustment allows for east or west declination setting to 180°
- Short and long sights for increased accuracy when sighting azimuth or vertical angles
- Precision aligned mirror with convenient "see through" sighting capability
- Cast aluminum body makes the Conventional Pocket Transit nearly indestructible
- Durable leather carrying case
- Limited lifetime warranty
