Abstract
A receiver for a laser transmitter for use in surveying, comprising a housing and a sensor module pivotably mounted on the housing so that, by pivoting the sensor module relative to the housing, the device can detect a laser signal coming from sources at various angles to the housing. Also, a battery receptacle comprising a housing which defines a cavity and an opening at one end of the cavity for receiving a battery. First and second recesses are formed at the other end of said cavity and are shaped to receive terminals on a battery which is inserted in the cavity. First and second electrically conductive springs are mounted in the first and second slots, respectively. A door is mounted on the housing to close the opening and to retain a battery in the cavity.
