This is a great jewelers loupe ideal for sexing your geckos and features a 30x magnification and a 60x magnification lens, both illuminated with a very bright LED light. Every gecko breeder should own one. Pores are easily visible under the 60x and 30x lens. 60x will give you a nice close up and the 30x is quick and easy to use for identifying the sex of your geckos. Using a loupe to watch the development of your fruit fly, isopod, and springtail cultures is a great way to ensure you are producing healthy colonies of feeder insects and microfauna. Hard plastic-shell storage case included!
