If you buy that type of scope,make sure to use a memory card in it and not just take photos of the screen and post them. Appraisers use a 5x or 10 Jewlers loupe. You should use a hand held loupe with a 10x power. A Hastings triplet is best but a regular doublet is fine. A USB scope is really only handy for taking and posting photos.
