The HM-117A finds location and approximate depth of rebar, metal pipe, conduit and metal framing through concrete and most nonmetallic construction materials at depths up to 6in (150mm). This economical device is well suited for occasional use or for preliminary scanning of large areas. When compared to precision rebar locators, this unit is less accurate and bar sizes are more difficult to determine.
The HM-117A is fast and easy-to-use with comfortable hand grip and one-touch operation. The sturdy plastic case is shock and splash resistant. The large LCD display quickly indicates both location and depth of embedded metal objects. Differentiates between magnetic and nonmagnetic metals based on their magnetic properties. Location accuracy for rebar is approximately ±1in (25mm), dependant upon size and depth of the bar.
Powered by a 9V alkaline battery (not included).
