Barra Edge or something similar
Mictrack MT700 series are similar to DMT.
The MT700-W battery life is up to 2 years, and the MT700-NW battery life is up to 7 years.

Has anyone gotten the Barra Edge to work? Or should all DMT devices work?
I'm particularly attracted to the ~7 year battery life, though I'd settle for 1-2 years if anyone has any suggestions.
Battery life and $50/unit (I'm going to need a lot of these) and waterproof/rugged are my primary concerns.
Thank you
