a shaft including an elongated profile having an adjustable length;
a handle attached to a first end of the shaft; and
a head-assembly attached about a second end of the shaft, the head-assembly including a mid-section, a first half pivotally attached to a first side of the mid-section, and a second half pivotally attached to a second side of the mid-section, the mid-section being attached to the second end of the shaft, the first half and the second half being pivotable between a folded-position and an in-use position, and wherein the first half and the second half in the in-use position are used to level the surface,
the head-assembly further includes a pop-out mechanism, the pop-out mechanism including a first spring in communication with the first half and a second spring in communication with the second half, and wherein the first spring and the second spring impart a permanent bias on the first half and the second half toward the in-use position,
