Sunray YF-1 in-line probe for the Garrett Ace series & GTP-GTAX series detectors.----I purchased this probe brand new on 3/20/'12 and it has never been used, just tested it out and it works perfectly.---It is the new black probe with red tip protector on it--it's "showroom perfect".----The reason I am selling it is because I'm not keeping my Ace 250 and I don't have a use for it.-----Save yourself some big bucks on a new probe at a used price.---They list for $194---asking $110 delivered (U.S.)--payable by USPS money order.-----------Thanks for lookin, Del
