That old geologist who swore by hand lenses over digital microscopes

Back in 2018 I was doing field work near Moab and this retired guy kept telling me to ditch my digital scope for a simple 10x hand lens. I thought he was just being stubborn about new tech. But after my scope fogged up and died on a humid afternoon, I borrowed his lens and actually saw grain structures way clearer. The depth of field on those cheap plastic lenses is hard to beat for spotting quartz veins or feldspar twinning. Now I carry both but use the hand lens 9 times out of 10 for quick identifications. Has anyone else gone back to old school tools after relying on gadgets?

I used to be all about the newest tech too, thought anything old was just people being afraid of change. Then I had my own digital scope freeze up on a cold morning and I was stuck with nothing but a cheap hand lens I'd thrown in my bag. That was the moment I started seeing things I'd missed before, like the tiny hematite stains in a sandstone sample I'd walked right past with my fancy scope. Now I grab the hand lens for the first look almost every time, it's just faster and clearer for the basic stuff.

Same thing happened with my old GPS unit in the field. It died right when I needed it most, and I had to navigate using a paper map and a compass that I'd never actually learned to use properly. Having a backup low tech option saved me that day and taught me that the simple stuff rarely lets you down.
