NSL500B Transit/Level Comments
Your review: I like the basic instrument. Still checking its adjustment, as received. Some corrections may be necessary.
Pros: Well-designed, well-made instrument for my purposes (mapping my property, not professional surveying).
Cons: Owner's manual deficient. Not all controls identified/explained. Horizontal angle measure description seems to fit vertical better. No "horizontal circle positioning knob" found, or its "clamp".
