GPS tracking devices are extremely helpful and a great way to reduce the number of surveillance hours needed to gather the evidence that you need.  

There are a lot of devices that are available for purchase on the internet. We have over 20 years experience using these devices and will be able to point you in the right direction. We are frequently asked to conduct surveillance after our client has already purchased a GPS device. Unfortunately the client picked a cheap device where the battery only last 3-4 days. There are dependable devices out there that will last a month or longer before needing to be recharged. I recently tested (July 11th thru September 22nd 2022) out the device listed below and it has tracked my vehicle for the past 3000 miles on three Ultimate Lithium AA batteries. Amazing performance and it's still going.  

The more frequently the device updates (reports a location to the internet) the more power that is used. So I have my device set to update every 5 minutes while there is movement. 

Some device out there can report every 5 seconds and other devices never go to sleep. This method uses up precious battery life requiring you to risk removing the device to charge it up and then replacing it. My choice is to place it once and forget about it. 

The device listed below can be placed (hidden) inside a vehicle or if you purchase the magnetics ($9.95), it can be attached under the vehicle to the metal frame. Once the device is attached, you can begin tracking by using a regular computer via the internet or the companies free app on your phone.


The link below will take you directly to the company's website and the device (Oyster 3). You will see three dropdown boxes for ordering. Select 5 minute updates, month to month billing and yes or no to order the magnetics. 

No GPS device is perfect. Things can go wrong with any technology. Placement is everything. Always test things out before needing it for a critical situation.
