Looking for a passive GPS tracking device.  Everything I have found on the market is obsolete and overpriced, especially compared to the active trackers that are essentially cellular devices that respond and/or broadcast their location.  The drawback to an active device is that it typically requires a data contract and is much more traceable.The best of the bad options I have found in the passive arena is the Tracking Key but it is widely panned because LAS's products are not weather-sealed (just put it in a plastic bag is their suggestion), their support is abysmal, and all cost at least $150!  (There's no question that in volume a controller, GPS module, USB interface, battery, magnet, and rubberized jacket should command a market price of at most $100.)Looking for a passive GPS tracker with the following features:Weather sealed(Optional) magnetic attachmentAntenna works when installed under a vehicleBattery-efficient: I.e., it goes to sleep when not moved for a certain period.
