A power hand drill has a subsurface object locator for detecting the presence of an object beneath a surface being probed with the locator. The drill has a housing with a flat accessory mounting surface having a pair of attachment tabs. The locator has a locator housing with a flat base and a pair of key hole slots engaged with the tabs for detachably mounting the locator housing to the accessory mounting surface of the drill housing. The locator includes sensing circuitry contained within the locator housing for detecting subsurface objects and has an object indicator mounted to the locator housing and connected to the sensing circuitry for indicating the presence of a subsurface object. A contoured surface on the locator housing provides a handrest for gripping when operating the drill.
