A scoop has a handle attached thereto by a neck. The neck has a built in strain gauge supporting the scoop which measures weight in the scoop. An analog-digital converter converts the strain gauge output to a digital signal, which displays the weight as a readout (either metric or avoirdupois) on a panel in the handle. Control switches built into the handle or panel control the functions of the scoop, while indicator/annunciator lights indicate status. A level indicator is provided having a ball bearing resting freely on a conducting bottom plate forming a spherical sector of predetermined angle and a cylindrical sidewall having therein conducting elements. When the ball bearing contacts a sidewall conducting element it closes a circuit which switches off a level indicator/annunciator light, which when on shows that the scoop is level. The position of the ball bearing is visible to the operator, allowing correction of tilt. The predetermined angle is set between 8 and 12°, so that tilts greater than 4 or 6° are visually indicated.
