I actually hadn't realized that the Abney level was considered a
clinometer. The difference between the Abney level and clinometer to
which I referred would be like that between a transit with an external
vernier and a theodolite with an enclosed graduated circle.

The SUUNTO clinometer is much more portable and easier to read.

Functionally, they both do the same thing.

On further reading it becomes apparent that The Abney Level is also known as a
Clinometer, why I don't know as there seems to be no origin in the word.
However, there was a device marketted by the Vickers Co. as the "Inclinometer"
the main feature being that it was calibrated in slope ratios as opposed to
angles, it was used extensivly in road and rail construction for staking out
slopes with variable batter ratios. As a side note I saw a bucket full of these
devices sold to an antiques dealer at a auction for twenty pounds when the UK
Ordnance Survey sold all their old Dept Overseas Survey kit last year !
