Have had my Portable Lightning Detector 02020CA about 2 weeks now and have found that it will not detect any lighting at all when in Outdoor mode. I tested this again during an active storm last night. While outside, set to outdoor mode, it would not detect anything. If I put it in indoor mode I would get a detection alert for about 9 out of 10 of the flashes I saw. I was at least 20 feet away from any electrical devices and I also noticed that the missed strikes often came up an interference alert. Also saw once the distance got to 1 mile it never changed even as the storm moved away Suggestions?
