The #1 Tool for the Non-Destructive Investigation of Earth and Concrete

The SIR-3000 is GSSI’s latest GPR data acquisition system and the industry’s number one choice for data accuracy and versatility. It is a tool developed for saving time, money and even lives.

The SIR-3000 is a small, lightweight system designed for single user operation. This product provides the essential features and flexibility that experienced GPR users look for, as well as simplified, application specific user-interfaces for inexperienced GPR users. In addition, the SIR-3000 incorporates advanced signal processing and display capability for ‘in-the-field’ 3D imaging. Unlike other data acquisition products on the market, the SIR-3000 is interchangeable with all GSSI antennas, making it an affordable and flexible option for multi-application users.

The Gemini III is designed to locate large, deep objects--like an iron chest, an ore vein or a metal pipe. With its two-box design, it offers much better depth penetration than standard metal detector. The Gemini-3 is used by professional treasure hunter, prospectors, geologists and public utility employees. Depending on ground mineralization and target size, objects may be detected as deep as 20 feet. A pioneer in the field of metal detector over 60 years ago. Fisher has been advancing the state of art ever since. The Gemini-3 is Fisher's best two-box ever.
