Low Viz scare ya ?

Absolute zero viz, that is where you can't see your fingertip on your mask, let alone a compass or other gauge, can be fun if you're searching for something. There's a challenge in doing an accurate search, with sufficient overlap and ensuring you're not running into anything.

Very satisfying too when you find what you were looking for and the owner reaches for their wallet in gratitude.

Absolutely.

Two highly valuable, yet disparate, skill sets: non-silting butterfly and tethered mudpuppy.
