The most recent change I've made to my dipping and scrubbing routine has been the addition of a cheap jewlers loupe. I also collect coins and have a few laying around. I saw something odd on one of my frags and couldn't make out what it was so I grabbed loupe and saw that it was absolutely nothing in that case. However, I was really able to get a really good look and a few frags later was able to see some eggs on one of the frags so I pitched it. Now it's a standard part of the dipping process for new frags. I know 100% that a coral QT is the way to go but every one I set up ends up being a frag tank...
My Wife thinks I'm a crazy person. She just so happened to come down to the basement when I was dipping in Bayer. There I was with my fan, gloves and my magnifier headband scrutinizing the tiniest imperfection on a monti. At this point I've upgraded from a simple handheld loupe to a headband that has lenses for both eyes. I thought I looked pretty cool but she clearly didn't!
