Hand-held measuring device

A portable, hand-held measurement device, comprising:

• transmitter means to transmit a signal at a target object;
• receiver means to receive a reflection of the signal reflected from the target object;
• processor means operably coupled to the transmitter and receiver means to obtain a measurement value, the processor means having storage means for storing pluralities of the measurement values and claculation means for calculating areas and volumes from the stored pluralities of measurements;
• display means coupled to the processor means for selectively displaying the measurement values and calculated areas and volumes;
• and
• switching means converting the measurements to a plurality of different measuring units.

• leveling means for assessment of horizontality;
• display means coupled to the processor means for selectively displaying the measurement values and calculated areas and volumes;
• and
• actuation means including a first button, depression of which operates to produce the measurement, and a second button, depression of which produces a calculation of areas from the measurements, said second button further operating to cause the processor means to produce a calculation of volumes from the measurements.
