Goldak 777-A Leak Detector - Pin-Point Underground Leaks with Industry’s Most Accurate and Proven Leak Detector

Goldak 777-A Leak Detector is a preferred choice for experienced underground leak locating professionals, trusted for decades. This advanced model is highly sensitive, offering clear and accurate results through its low-noise circuitry. Goldak’s 777-A Leak Detector is ranked #1 for detecting residential and commercial slab leaks. With solid aluminum construction and a high-impact foam-lined compact carrying case, it’s built to last and perform in any environment.

Professionals in plumbing, contracting, water works, and plant maintenance have long relied on specialized equipment for detecting and pinpointing underground water leaks. The Goldak 777-A provides a solution with its proven ability to detect leaks caused by mechanical vibrations traveling through pressurized pipes, making it essential for efficient leak detection.

Liquid Leak Detector - Simple Operation

To operate, the technician places the microphone probe on the pipe and all exposed fittings (e.g., hydrants, shut-offs, valve stems, water meters). The microphone converts mechanical vibrations to electrical impulses that are amplified and displayed on the meter, enabling leak sounds to be heard through headphones. Leak location is achieved by comparing sounds from multiple detection points along the water system. It’s an intuitive process that can even detect leaks through pavement or flooring with the ultra-sensitive microphone.

The Goldak 777-A Model Comes Complete with These Two Microphones:

1. M-79 Series 2 Microphone – Ultra-sensitive, disc-shaped microphone included with all Goldak 777 Leak Detectors. It’s engineered for maximum sensitivity and sound quality (2 1/4” Diameter x 5/8” Thickness).
2. 71C-007 Microphone Probe – Standard 12" long probe for direct contact with test points like pipes, valves, or even concrete slabs when listening through carpet.
