| Zusammenfassung: | The utility model discloses a multi -functional digital geological compass appearance, including the instrument case and with instrument case swing joint's reflector and board subassembly, the board subassembly includes the short board of multisection, the adjacent mutual swing joint of short board. This multi -functional digital geological compass appearance has increased the measurement wide angle under volume invariant's the condition, compensatied current instrument of the same kind because of the board cross the short target angle of elevation of causing be greater than 60 or the angle of depression be greater than 45 o'clock unable defects of measuring the position. |
