The "NACHI" ticker puts all other TICKERS to shame....read the features below to see why.

SOLD OUT

Defective Grounds: Electrical equipment that has a metal enclosure
and is improperly grounded or has a defective ground will always
result in the Sensors tip emitting a steady red glow. If there is
enough electrical field present on the metal enclosure, the result
will be a steady red glow and an audible tone.

Always Ready For Use : No Switch required. Competing products require an
ON/OFF switch. Switches must be turned on and can malfunction
over time.

Sound & Visual Alert:  Sound and bright red glow indicates the voltage. With the NACHI TICKER, the audio alert does not go off from contact with staticelectricity, it only reacts to AC voltage. Our AC Sensor is able to tell thedifference between static charge and AC current. Competitors’ audioalerts constantly go off when the tool comes in contact with static electricity.

Why Probe Tip Flickers: This instrument is so reliable in locating voltage that it will react tostatic electricity by flickering. This is not to be confused with powercompany voltage which produces a steady glow. The audio buzzer will not react to static electricity.

Operating Instructions :The "NACHI Ticker" is a hand held device fordetermining the presence or absence of AC voltage in insulated
wires, wall receptacles, fuses, junction boxes, switches and any other
voltage carrying electrical systems. It is not necessary to disconnect
the system in question because no contact is required for operation
and current flow is not necessary to locate voltage. Simply touch the
plastic tip to a connection point or move it along an insulated wire. If
AC voltage is present, the NACHI Ticker will sound an audio
alert and an LED light in the probe tip will glow bright red. The
illumination will stop at a break in the circuit or wire, and this
allows the AC Sensor to be used as a troubleshooting instrument.
Always hold unit by its body (2). Keep fingers away from the tip (3).

Caution 2: In testing indoor romex cable where the fibrous filler becomes saturated with water, which is conductive, an electrical connection is formed between the filler and the ground circuit. The length of cable that has become wet is essentially shielded. If a voltage is present on a conductor in this cable, the electric field normally radiated by the voltage will be attenuated by this shielding and the AC Sensor may not glow even though a voltage is present. Therefore, always
approach wet indoor romex cable with utmost caution. NOT
FOLLOWING THESE CAUTIONS MAY RESULT IN BODILY HARM. Cable of this type is specified for indoor use only. It will be subjected to immersion in water only in rare conditions such as flooding. Outdoor romex cable is not effected by water.
All sensors of this type will exhibit the same characteristics when testing wet indoor romex.
