Order both our identification devices together as a discounted bundle. Our two old-school ‘apps’ don’t need a phone or WiFi, and won’t run out of battery. The Cloud Selector helps you identify 20 different cloud formations, from the common Cumulus cloud to the rare and fleeting Fluctus. The Light Effect Selector teaches you to distinguish 16 different optical phenomena caused by the sunlight glinting off droplets and ice crystals of clouds and fog – from ‘sun dogs’ to coloured arc and halos, you’ll learn to spot the different types. These Selectors are essential kit for any self-respecting cloudspotter.
