Just a quick follow up on that post. I received my metal scanner yesterday around supper time. I put a battery in it this morning and tested it out on some of my pallet wood lumber. It immediately detected some hidden nails and screws in my wood that I did not see! Very nice! The nails were easy to take out, but the broken screw buried into the lumber is a real pain in the behind. I'll probably end up using that lumber where that hidden screw will not matter. I'll just mark the wood with chalk or something so that i don't cut it at that point or run that wood through a planer. My goal is to detect any hidden metal in the boards, and then decide if it's worth my time to remove the item or use that wood for a different project.

As to the quality of the metal scanner.... Well, it's just a cheap plastic item. I don't think it would survive a drop. So, you better be careful with this scanner. Having said that, this scanner was less than $20 and I don't think you can realistically believe it was built to be tossed around.
The generic instruction manual was obviously printed to cover a number of different models. The model number of this unit was printed in a different font and size than the rest of the instruction manual. Not a big deal, but you know that the manual is not specific to the unit you purchased. Also, the instruction manual talked about a feature that my scanner does not have, and left out a button on my scanner which was not included in the manual. On the plus side, considering this unit comes from China, the manual was translated into English very well and was easy to read. Not too many features on these metal scanners to worry about anyway.
So, on Day One of use, I'll give this inexpensive metal scanner a 5 star rating, considering the cost of the unit and performance of finding hidden metal in the lumber that I myself did not see. I'll just write off the expense of this scanner over the life of the warranty, and if lasts longer than that, I'll be more than happy. Amazon return period on this item is 30 days, no stated warranty on the item after that. So, consider that before you make a purchase as I don't expect that Chinese company to be around, say a year from now, if the unit fails.
In comparison, the
Cen-Tech scanner from Harbor Freight costs $40.00 and only has a 90 day warranty.

As far as I can tell, they are basically the same. Probably will work good until you drop them, then you will have to replace it.
