We are upgrading our gps tracking and have 5 j2 shadow trackers for sale. We purchased these a little under one year ago. Each unit has the antennae, dc power adapter, and a dc direct connect option. Also included is the Shadow Tracker Lite software package for report generating. These were purchased from ATTI and you can check their website for more detailed info. Our cost for the entire package was just under 2k. Will sell as complete package only for $950.00. PM me with any questions.
