Best hand lens for looking at bryophytes outside?

[tristanmcknight]

My family (my dad and sister wrote this field guide to mosses) generally uses the Iwamoto Achromatic 20x. Most lenses with greater than 10x magnification are frustrating because they have a tiny diameter, but this one is able to be broad, magnified, and not have lots of artifacts. They’re also rather expensive (usually $100+), but it’s worth it.
