You must be a forester. I did not see the clinometer option in yours. I assumed foresters would have a clinometer.
Geologists usually relied on Brunton Pocket Transits. They cost so much almost nobody bought one of their own, schools and employers provided them instead. I got one that was army surplus, had to change a few parts in it.
