I got these flashlights for our late night fishing trips. We both can have one when we go this spring and summer. These flashlights come with batteries. I didn't realize that they can also be used for fungus detection. These are water resistant and have 4 modes, and one is Ultra Violet. One of the modes is the SOS help signal. The lighting distance is about 300 meters. Great for work, lost electricity, detecting cat and dog urine, detecting stones such as jade. These are made from durable grade aluminum You can use the flashlight to break windows such as cars if you would ever need that. You get 2 flashlights, 6 AAA batteries, 2 hand straps and instruction manual. Don't forget the clip so you can hang it wherever you want like your shirt collar, purse, fishing bag and any place else you want to.
