Would this gauss meter be any good?

So, I like to grab odd things, sometimes expensive things even fi I don’t use them much, I just bought a $120 chronograph for my air canon, and have used it only a few times lol.

Well, I now put some big caps into a nice big coil I found (I’m uploading a video soon and will link it), and it pulled in (just a bit) a set of metal shears that weight 377 grams. It also shoots small metal things up a few inches into the air and I am curious how powerful a magnetic field it is making. I looked on ebay and fond this gauss meter, do you think it would be any good, or shitty since it’s a “ghost hunting” one.
