These get slammed on the Reddit metal detector sub for being sub-par with the better metal detectors. That's fine. It's not a high-end machine. But it's a good beginner's machine. Accurate enough, dependable enough, easy to assemble and start using. You take it out, you find stuff. It takes 2 9 volt batteries, so if 9 volt isn't your thing, look elsewhere. I went ahead and got a 9 volt recharger and some extras.I will say this: my 2 daughters and I have a blast taking this thing out "treasure hunting," along with a pinpointer. They are absolutely thrilled when it beeps and can't wait to do what kids love to do -- dig. The 9 year old gets an orange pin pointer, the 5-year old gets a magnet and a spoon (I know, not conducive to proper metal detecting) and daddy get this thing and both a big shovel and the smaller shove that comes with this set (which is a heavy duty little shovel, btw). Then we all go to town -- team building, disussing what metals are -- steel vs gold/silver, magnetic, etc., Hoping to find "fossils" and "treasure," we treasure by searching and finding whatever we find.Easy assembly, easy to use. Great entry level machine. Will you outgrow it? I hope so. I hope this opens up new possibilities and dreams for anyone who uses it. But it's a good starter within this price range to see if you (or you littles) catch the treasure-hunting bug.
