Just purchased the mi6 pinpointer. Purchased from a person who never used it . Charged it up and it won't cycle thru the settings. Sometimes won't even come on. Talked to the person and he doesn't have the purchase receipt for warranty. Went on the xp deus website for warranty and it asks for purchase invoice.. The seller said he purchased it last year. Is there anything that I can do to have this repaired by xp dues? Thanks.
