I have the Little Wizard... and it misses nails/screws, I wouldn't recommend it. I replaced it with the harbor freight wand type, which works great, and has never failed, although I have never used it on logs, but works great on pallet wood and reclaimed 2" construction/demo lumber.there are also metal detectors. Here's an example - https://www.amazon.com/Wizard-Little-Woodworking-Metal-Detector/dp/B0093FJENM I have no idea how well it works but there are a lot out there. In theory a metal detector will work better than a magnet.
Note that both only detect ferrous metals. So stainless steel, copper, brass, lead don't get detected.
I have one and can recommend it...I have the Little Wizard... and it misses nails/screws, I wouldn't recommend it.

You can get them for $30 - $50....

Truth. I got some 2x4s from HomeDespot and was cutting them on my 10" SCMS. About half way through my cuts started coming out terrible - really ragged. I stopped and looked at the blade. It had a twisted tooth sticking about 1/4" to one side. Went back through the cutoffs and sure enough there was a screw I'd sliced through and didn't even notice. This was with brand new, just purchased 2x4s. Fortunately, the blade was an older one that I expected to replace at some point but it is still disheartening to have to trash a blade because of someone else's negligence.I find the most effective tool for finding embedded metals to be a freshly sharpened combination blade..... unfortunately
