SPY Hawk Turbo PRO is The Best Real Time GPS Tracker Slap & Track 4G Portable GPS Tracking Device - Worldwide Location - Weatherproof Magnetic Case - GPS Tracker for Cars, People, Fleet, Trucks

This is the one to get. The GPS service is very accurate and the extended battery has lasted 15 days on a single charge. The secure, online interface is also very well-done. I have had no problem setting up geofences, live-tracking, nor using the playback option. Spy Associates are incredibly helpful getting the customer setup done easily and in a friendly manner. I recommend this GPS tracker 10 times out of 10.

These comment all sound like sales pitches. SUSPECT to me...

Easy to use

I use this Tracker on a daily basis in law enforcement. I have used units that cost up to $5000.00 this one is just as good if not a little better that those.First this one is easy to place on a vehicle....very quick. The magnet holds really well. The more expensive ones come in 2 pieces. The unit with batteries and a extra battery pack that attaches with a wired connector. No need for this on this unit. Everything is housed in the water proof box. Easy to change out if you need it longer than the battery works. I have used this unit on a single vehicle for as long as 5 weeks. Of course the movement of the vehicle determines this.Second the mapping display for this unit is FAR better than any other out there that I have seen. VERY VERY accurate. It allows as many fences as you like and the alerts for crossing fences are very fast.For the money I haven't found another tracker that comes close to this one BUY IT!!!
