My husband love to metal detect. This magnifying glass with LED light and little jewlers window is PERFECT for him. He grabs it anytime he has issues reading dates on coins he has found. Or old stamped pieces also works great when i am yard saleing and need help seeing and decifering makers marks on objects I might interested in. Takes 3 AAA batteries (not included)for the LED lights. #rankboosterreview #Sponsored #BreaDeep https://www.amazon.com/Magnifying-BreaDeep-Handheld-Magnifier-Electronics/dp/B017GS1AH0
