Michael T Yes, this has: 1) Time Sleep (Sets how much time you want the unit to sleep) 2) No Sleep (Activated 24/7) 3) Shock Sleep (Sets the level of vibration for it to wake up and report 'SHOCK') I have my unit set to 'No Sleep' as its directly wired to the battery, and it really takes no power at all. This item can be left ON for weeks before it will even effect a car battery bu 0.5%

Michael T NO!, this needs a clear view to the sky, encasing it in aluminium will cause a Faraday Cage Effect and stop the signal. It will not fall back to GPRS (Cell tower triangulation) or WiFi IP Address Location (Google Connect). And just to be sure about it, Canada will be getting rid of 2G for the most part by 2020. I'm in Edmonton, and looking for a GPS Asset Tracker with 3G, WiFi and GPRS location. My eBike is over 10K my cost to build.
