1. Surveillance equipment: Private investigators use a variety of cameras, audio recorders, and GPS trackers to monitor and track individuals.

2. Computer and mobile phone forensics: Private investigators may use specialized software to recover deleted data, such as text messages and emails, from computers and mobile phones.

3. Social media monitoring: Private investigators may use tools to track an individual's activity on social media platforms, including Facebook, Twitter, and Instagram.

4. Background check tools: Private investigators may use online databases and public records to gather information about an individual's criminal history, employment history, and financial records.
