Frequently Asked Questions

What Tracking Devices Do Private Investigators Use?

Private detectives call upon a wide array of surveillance tools to conduct investigations, but the security product they use most to catch a cheater is the magnetic GPS tracker. The reason private investigators prefer wireless GPS trackers with magnet mounts is that they allow any PI to quickly and easily attach the GPS vehicle tracker underneath an automobile without a driver knowing. Not to mention, the legal reasons that make it unlawful for a private investigator to enter a person’s automobile without first acquiring a search warrant. 

How Do Private Detectives Track Down People?

Most private detectives are actually ex-law enforcement agents such as retired police officers or some other form of government agents. But the reality is that PIs do not have the same wide range of investigative surveillance tools as active law enforcement. However, investigators still have far more tools and skills than normal private citizens. Private investigators can access social media accounts, interview friends/co-workers, access databases, and use personal GPS tracking devices to track down people. They also are very fluent in accessing public records so they can quickly access a target’s name, phone number, address, social security information, and other personal details. Lastly, ask any private investigator and they will tell you they have many friends in law enforcement and can ask for a “favor” if they need to find something outside of the public domain.

What Are The Benefits Of GPS Trackers For Private Investigators?

Absolutely, GPS trackers are an invaluable tool for private investigators. They simplify tracking the location of people or objects by providing real-time gps data. GPS trackers can also store historical movement data for future analysis, significantly aiding in cases like theft investigations or infidelity investigations. Essentially, a tracker allows investigators to gain insight into their subjects’ routines and patterns without any intrusive or time-consuming stakeouts.

Are Private Investigators Allowed To Use A GPS Tracker On Someone’s Vehicle?

Yes, but the legality varies. In the U.S., the 4th amendment addresses issues of personal privacy, but it’s not clear cut. As per the ruling in the case of U.S. v. Jones, a licensed PI might need permissible purpose or consent from the registered owner to place a tracker on someone’s vehicle. Therefore, always consult with your investigator licensing board or legal counsel to ensure you comply with local and federal laws.

Are There Any Personal Safety Benefits Of GPS Tracking Devices?

Absolutely, there are! Apart from its use in professional settings like private investigations or fleet management, GPS tracking devices also provide advantages for personal safety. For instance, they can be used to monitor the whereabouts of young or elderly family members to ensure their safety. An OBD2 GPS tracker, which plugs directly into the car’s diagnostic port, can notify you if the car has moved outside a predetermined area. This makes them great tools for maintaining peace of mind when it comes to your loved ones’ safety.
Private Investigator GPS Tracking Devices – Final Thoughts

Before using any hidden GPS trackers it is important to understand the GPS law in your particular area. Real time GPS trackers are 100% legal to purchase but the way a person uses a spouse GPS for mobile tracking could be illegal. This is why you should contact an attorney or licensed private investigator before using any personal tracking GPS surveillance systems.
