PURPOSE: A float tester is provided to form a sensor sinker by using a non-magnetic material and to be used for decoration by emitting light. CONSTITUTION: A float tester comprises a solenoid(10), a signal supply part(40), a buoyancy measuring device(30), and a sensor sinker guide(20). The solenoid generates magnetic field when receiving electric signals. The signal supply part supplies signals to the solenoid. The sensor sinker of the sensor sinker guide reacts to the magnetic field and is made of a non-magnetic material. The buoyancy measuring device is able to move up and down in a fishing float and measures the volume of the float. |
