We take a look at the klein tool non contact voltage testers.
NVCT-2p and NCVT-3p are very similar but the 3p has additional features such as a flashlight.

Both are great tools and seem to work properly. Have had no issues so far. Pretty much has a high sensitivity mode and a low sensitivity mode. Can also work in silent mode.

When using something like a non contact voltage tester make sure you get something that is absolutely reliable. Your life may depend on it.

NCVT-2p
Non contact voltage tester's dual-range capabilities allow tester to detect from 12 to 1000 V AC or 70 to 1000V AC for a broad variety of low-voltage or standard voltage applications
Electrical voltage tester detects voltage with simultaneous visual and audible indicators
Non-contact detection of low voltage in security, entertainment, communications, environmental control, and irrigation systems
Green light indicates no voltage
Lightweight, compact tool with pocket clip provides convenient storage and quick access
Auto power-off feature conserves and extends battery life
CAT IV 1000 V rating provides expanded operation and protection
Screw-thread battery cap with O-ring ensures protection against dust and water ingress
6.6-Foot (2 m) drop protection
IP54: Dustproof and waterproof

NCVT-3p
Non contact voltage tester's dual-range detects from 12 to 1000 VAC or 70 to 1000 VAC for a broad variety of low-voltage or standard voltage applications
Detects voltage with simultaneous visual and audible voltage indicators
Bright flashlight illuminates work area and may be used independent of voltage detection function
Green light indicates no voltage
Lightweight, compact tool with pocket clip provides convenient storage and quick access
Auto power-off feature conserves and extends battery life
CAT IV 1000V rating provides expanded operation and protection
Screw-thread battery cap with O-ring ensures protection against dust and water ingress
