The SILVA Clinometer is a popular clinometer for all types of vehicles. It has two scales, one ±35° and a fine tuning scale ± 5°.
The SILVA clinometer is used for checking the heeling angle on sailing boats and for the power-trim check on powerboats. It is also a perfect working instrument for other applications, such as making sure that different vehicles and equipment sits “level” or keep the desired a angle.
For angles up to ± 5°, read the top precise scale, for angles over ± 5°, use the lower scale for readings up to ±35°.
