These methods work well on the Garrett GTI Series and the Garrett ACE Series metal detectors. If you swing another make or model, you will have to try a different approach, but the same principles prevail. Keeping the batteries warm keeps them running longer, and keeping the electronics warm, keeps the LCD from slowing down and the knobs from getting stiff. Remember to read your manual and operate your detector at the recommended temperature range. If your detector permanently malfunctions from operating in the cold, it could void your warranty. Now having said that, I have run my ACE 250 at - 25 with no problems, and -10 with my GTI & GTA models.
