My newest version of the Deca Meter has a slimmer design with a more elaborate lighting system. Two green LEDs light in the front antennas and pulse and flash with the color changing LED that illuminates the main viewscreen. In the clear dome a series of amber lights chase in different patterns that can be selected by pressing the trigger on the handle. Refer to the video below for all of the light functions. All of the lights run off of a 9volt battery installed underneath the body. A small hook has been added to the back underside of the meter to let you clip it to the belt's key fobs. Weathering has been done to make it look used and abused. The labels are custom designed in Photoshop and printed on quality label paper.
