Detector(s) used Garrett Ace 250 Primary Interest: All Treasure Hunting Jul 12, 2020 #1 I found this in a $2 yard sale mystery box. I thought maybe some kind of thermometer. The plastic tube doesn't have a hole in the point and seals with an o ring. I haven't been able to find any markings on it. Any ideas? Thanks for any help.
