GPS tracking technology has become one of the most effective tools in an infidelity investigator's toolkit. When used legally and combined with physical surveillance, GPS tracking provides a powerful combination that can build an airtight case — or quickly put unfounded suspicions to rest.

Types of GPS Trackers

Real-Time Trackers transmit live location data to an app or online portal. The investigator (or authorized party) can see exactly where the tracked vehicle is at any given moment. These are ideal for catching patterns and coordinating physical surveillance.

Passive Trackers record and store location data locally on the device. The data is downloaded and analyzed after retrieval. Less expensive than real-time trackers, but require physical access to the device to retrieve the data.

OBD-II Trackers plug directly into the vehicle's diagnostic port — typically located under the dashboard on the driver's side. They draw power from the vehicle and are harder to detect. These are popular for long-term tracking cases.

The Legal Framework in Pennsylvania

This is critical. GPS tracking laws in Pennsylvania are nuanced:

  • A vehicle owner may generally place a GPS tracker on their own vehicle, even if their spouse drives it.
  • Tracking a vehicle you do not own, without the owner's consent, may violate Pennsylvania's wiretapping and surveillance laws — which are among the strictest in the nation.
  • The specific legality depends on vehicle ownership, the nature of the relationship, and how the data will be used.
Always consult a licensed private investigator or attorney before placing any GPS device on a vehicle. Illegal tracking can result in criminal charges and evidence that cannot be used in court.

A Real-World Case Study

The following is an anonymized account of a case handled by Kanenson PI.

"Angela" had been married for eleven years. Over several months, she noticed her husband staying late at work multiple nights per week — but the financial records didn't show overtime pay. He was dismissive when asked about his schedule and had begun keeping his phone face-down and password-protected.

Angela contacted Kanenson PI. Because the family vehicle was registered in her name, we legally placed a GPS tracker on it. Over the following two weeks, we documented repeated visits to an apartment address that had no connection to any employer or known friend.

Combined with physical surveillance that confirmed a second person accompanying him to that location on multiple occasions, Angela had the documentation she needed for divorce proceedings. The evidence was court-admissible and the case was resolved without prolonged litigation.

GPS + Physical Surveillance: The Strongest Combination

GPS data alone tells you where someone was. Physical surveillance tells you what they did there. Together, they build a complete evidentiary picture:

  • GPS reveals patterns — repeated visits to the same location at unusual times
  • Physical surveillance captures who they met, what they did, and how long they stayed
  • Combined documentation is far more compelling in court than either alone

The DIY Warning

DIY GPS tracking carries serious legal risks in Pennsylvania. Placing a tracker on a vehicle you don't own — even your spouse's car — without proper legal basis can result in criminal wiretapping charges, civil liability, and evidence that is entirely inadmissible in court proceedings.

A licensed Pennsylvania private investigator knows exactly what is legally permissible, documents everything properly, and ensures that evidence gathered will hold up where it matters most.
