3. Tile Mate – Best Bluetooth GPS Tracker For Private Detectives 

Tile Mater GPS


Top Features:

  1. Very Small & Only $29.95
  2. Little Logic Required To Handle Setup

Tile Mate serves as a practical tool for private detectives handling sensitive cases such as child custody disputes or investigating infidelity. This tracker can be discreetly attached to commonly used items, allowing investigators to monitor the movement of these items within Bluetooth range. Its ability to ring through the app or via smart home devices aids in quick location identification when items are nearby.

For items beyond Bluetooth reach, Tile Mate’s last known location feature on the app provides investigators with crucial data points for tracking movements or establishing patterns, important in custody or infidelity cases. The option to make a phone ring, even when set to silent, can be particularly useful in locating a client’s lost or hidden device, potentially uncovering critical evidence.

The anonymous nature of the Tile Network extends the search capabilities without compromising the privacy or confidentiality of the investigation. This feature can be pivotal in recovering items that are crucial to a case but have moved beyond the immediate search area.

Compatibility with iOS, Android, and smart home assistants ensures that private detectives can use Tile Mate with their existing technology setup, offering versatility across different cases. The tracker’s IP67 water-resistant rating, three-year battery life, and 250 ft Bluetooth range make it a reliable tool for extended surveillance in varied environments, essential for complex investigations such as child custody cases or catching a cheating spouse. 

When it comes to the issue of GPS tracking, Tile is a top seller (50,000 Amazon reviews) and therefore made our list due to consumer demand. However, the tracker has some shortcomings such as location services always needing to be turned on your mobile app, WiFi connection, and other design flaws. With that being said, the product information is pretty clear in that this really is not the best vehicle tracking device for investigators regardless of the number of online reviews. 

What Buyers Are Saying About Tile Mate

One Amazon buyer stated, “My husband can find his keys now”. And the expert at PC Mag gave the mini GPS tracker 3.5 out of 5 stars.

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.

The Supreme Court changed federal laws by ruling police and PIs need to acquire a warrant or get authorization before hiding a tracking device on a car so as to not violate a person’s fourth amendment rights. So make sure you follow all the legal rules before using this micro tracker that can be hidden easily under any vehicle.
