A rugged, reliable tool for precise geological measurements, this magnetic geological compass delivers precise strike and dip measurements with reliable magnetic alignment, ensuring accuracy in strike, dip, and orientation during fieldwork.
Precision Compass with Damping System and Clinometer Scale
- The magnetic geological compasses should be kept away from strong magnetic fields, as these can affect their accuracy. Please avoid using them near magnets, electronics, or large metal objects.
- The compass needle's reading error before and after rotation does not exceed 0.5°, with eccentricity-related error at 0°–180° and 90°–270° also within 0.5°, and the protractor reading error not exceeding 0.5°.
A Durable, Multi-Functional Compass for Outdoor Use
- SISCO high accuracy magnetic geological compass is a versatile tool designed to measure direction, slope, gradient, vertical angles, horizontal distances, and more.
- This geological compasses comes with a durable leather case for extra protection and easy portability. Commonly used in hiking, survival, surveying, forestry, military, mining, and meteorological applications.
Applications
Geological compasses are used for measuring the orientation of rock layers, faults, and geological structures in field studies, mapping, and resource exploration. They provide accurate strike and dip readings for structural analysis, slope stability assessment, and site evaluation in geology, mining, civil engineering, and environmental applications.

Q1: What is the purpose of a geological compass?
A1: A geological compass is used to measure the orientation of rock layers, faults, and other geological features. It helps geologists determine the strike (the horizontal direction of the rock layer) and dip (the angle of the rock layer’s slope) of geological formations, which is essential for geological mapping, analyzing structures, and understanding earth's history.
Q2: How to use a geological compass to measure dip and strike?
A2: To measure the dip, hold the compass level and align it with the rock layer. For strike, adjust the compass to align with the horizontal plane of the rock formation. The readings give you the direction and angle of the formation.
Q3: Can I use a geological compass in extreme weather conditions?
A3: Yes, geological compasses are designed to withstand tough outdoor conditions, including extreme weather. However, it's important to store the compass properly when not in use to avoid damage from moisture, freezing temperatures, or excessive heat. Always ensure the compass is kept in a dry, protective case during severe weather to maintain its accuracy and longevity.
Tips: How to read a geological compass?
- Position the Compass on the Rock Surface: Place the base of the compass flat against the surface you want to measure (like a bedding plane or fault).
- Measure the Strike: Rotate the compass until the needle points north. Read the value on the compass dial that aligns with the side edge—this is the strike direction.
- Measure the Dip Direction: Look at which direction the surface tilts down from the strike line. This is the dip direction, usually perpendicular to the strike.
- Measure the Dip Angle: Use the clinometer: hold the compass perpendicular to the surface and read the dip angle (the angle at which the rock layer inclines from horizontal).
