No serious naturalist should be without one. Slim, compact, and easy to use it will always find a place in my rucksack or pocket. Only the other day I was using it when beach combing; it adds a whole new dimension to rock pool exploration. Be it bugs, botany, or beasties, it opens a whole new world in a user-friendly way. The next best thing to a pair of binoculars.
