Depth Gauges is an instrument for measuring the depth of openings, grooves, recesses, and so on. The depth gauge uses as its base the surface from which the measurement is to be made. According to the type of reading device, depth gauges are classified as height-and-depth gauges, Height-and-depth gauges with flat measuring rods have become widespread. Measuring the thickness of a groove or rods in the form of cylinders 2 mm in diameter for measuring depths in hard-to-reach places. On height-and-depth gauges the dimension is marked off directly on a scaled ruler; micrometric and indicator depth gauges have replaceable measuring rods whose indications are read from a micrometer.
Digital depth gauges commonly also include a timer showing the interval of time that the diver has been submerged. Vernier depth gauge to the object or hole to be measured by placing the instrument's head at the bottom surface of the object.

Anyone doing construction or remodeling work and in need of accurate measurements of the depth of a slot, hole or recess will find a Vernier depth gauge extremely handy.
