    3 Overview and Introduction 3 Overview and Introduction 3.1 Description of Product The Searchzone Sonik is an advanced ultrasonic gas leak detector for use in hazardous areas. It detects high pressure gas leaks within the protection area, in order to provide an early alert to a hazard. While the Searchzone Sonik does not indicate the type of gas, it will respond to any high pressure gas leak within the coverage area and so will protect against the release of dangerous gases, whether they be toxic or flammable.
