Since I have a teensy operating budget at work, and since a compass with a arrow that unfailingly points at the ground is $35 more than a compass which tells you which way north is, I've janked together my own damn protractor/plumbline so I can work out slope. However, small non-breakable weights with string attachable parts are less common than you might think. Fortunately, I also have a Saint Christopher medal hanging around. It works pretty well if you need to know where the ground is.
