Here's a gadget that I don't need but sorely want!  It's for measuring the diameter of trees, useful for determining whether a tree can be rightfully called a champion or heritage tree.  How often would I use it?  At least once, I suppose.

down in the south Pi is "3" ;) j/k

looks like it would easy enough to take a regular tape measure, and write on the back of it, various sizes, and divide by Pi; or just even a cloth style measure, which weighs nothing, and approximate in your head, or use calculator/phone or even a little wallet chart.

i suppose for a plumber, who is doing this day in and day out it might be useful.

actually, if the size is the pure limiting factor, you could make a string the right length, and trees that are bigger won't fit, and would be heritage, and lesser trees would meet or overlap and wouldn't be (and thus are edible?)

The limiting factor is my utter lack of confidence in my math abilities. ;)

insert joke here about doing an integral (tree) with limits :)
