Query: not bad

It arrived on time using super saver shipping or what every it was shipped of on the 14th received on the 17th I ordered it on a week end so I had to wait two day before it was shipped of from arizona so I placed my order on the 12th. Came in a brown cardboard box I unpacked it put it together and was ready to go. ( it is very easy to assemble don't even need instructions). I went to the back yard first and tried it out I went all around until I heard a beep I got a shovel and started digging about 4 in down or 10 cm depending on where you live I found a nail. it is no million dollar coin but it still found something and Im glad to know it works. P.S needs 2 9 volt batteries.
