Loupe Magnification

Hello. I wanted to get a loupe for watching trichomes. What magnification do i need in order to see them well? 10x, 20x, 30x or 60x?

I gotta variable one that does 60 to 120, the 60X is enough

30x and 60x... works fine for me!

I've got a 10, a 60 and a 100 (requires putting samples on a slide). More is better in this case but the 60 is great; it is LED lit.

I would also recommend a 60x
I've bought several ones,and this one is the best, it got a bigger lense
