Tried above water so far, works well!
I've always been fascinated by metal detectors and finding things hidden just below the surface. Vine showed me one, and yes please!
It's light, easy to pop the (included!) battery into, and a single push button to start it. No fancy settings, no learning curve, just battery, power, and go. I headed to the back yard, which is primarily sand thus easy to dig, to see what I could find.
Protip: Do not wear steel toed shoes for this activity, unless you'd like to find your own feet, again and again and again. Shoe change, and away we go.
Move the wand slowly over the ground to let it register. It will vibrate, make noise, and light up when it senses something, more of all three the closer or larger the object is. (For fun, I "found" a vehicle. Sounded like I hit the jackpot.)
My first score appears to be a child's porcelain coated iron toy pot lid that appears to have been buried for a while. It was about a foot down. As I dug, I kept checking the dirt I removed from the hole in case it was a smaller item hidden in a clump. Getting closer to my prize, it lit up all three lights and buzzed faster.
The next two finds are well-used, rusted out nails. They were closer to the surface, and the detector lit up easily to locate them. If I continue at this rate, I'll slowly build up enough scrap metal to upgrade my metal detector.
The kit includes a waterproof flashlight, which takes 3 AAA batteries, not included. It's a simple turn on and off at the base, and decently bright. There's also a storage bag for everything - the velvetish bag seems a poor choice for something used in water as it may not dry as well as a mesh bag would. There's a lanyard for the metal detector as well, but I did not use it.
