Thanks. I had totally forgotten about that concept. I guess that was a battery interface board that fit underneath? These concepts eventually led to the Power Perch.
With the new tracker I'm working on, you shouldn't have to worry about losing more altimeters. I had a few false starts on the design, but last week an encouraging range test makes me more confident that the end result will be pretty awesome.
Oh, so the secret new product is a tracker... Cool!
How have you been Adrian? It's been years since I met you down in Colorado.
