摘要：

An improved angle deciphering and leveling device that transmits a radio frequency to a receiver located on or near the person using the level and also to a second receiver on or near a person who can double-check the level-user's work. The level works with a tilt switch that rotates about a shaft. The shaft is connected to a knob and spool. The spool is attached to the shaft. The tilt switch is attached to the spool. The tilt switch corresponds to a dial face that reads in angular degrees. When the tradesman sets the knob to the desired angle, the tilt switch corresponds to that angle and when the level is tilted to the preset angle a radio-frequency transmitter is triggered. When the transmission signal is received by the proper same frequency receiver, a alarm will sound verifying the angle has been reached. An on/off power switch will shut off the level when not in use.
