Circuit Alert Screwdriver — No more 'shocking surprises'

I'm reminded of those news stories about apparently healthy people, usually young men, who suddenly, out of the blue, while they're at home doing nothing special, drop dead.

The next paragraph usually reads something like, "the first sign of an enlarged heart is often sudden death."

Like, how is that a "sign?"

Seems to me a sign indicates something to come, rather than being self-referential.

But I digress.

From the website:

Circuit Alert™ 4-in-1 Screwdriver

Voltage-sensing screwdriver means no more shocking surprises

Never get stung by a hot circuit again.

Oh sure, you turned off the circuit breaker before you started working.

But are you really sure it was the right one?

Now you can do a quick double check without taking the time to reach for another tool.

The Circuit Alert Screwdriver senses AC voltage for 50-600V before contact and warns you with a flashing light and beeping.

Features:

• Hardened bit holder holds 2 double-sided bits to give you #1 and #2 Phillips plus 3/16” and 1/4” slotted bits — also compatible with any other standard hex bits

• Durable ABS plastic resin handle with cushioned grip material

• Twist on/off switch on the end of the handle

• Insulated steel shaft for greater protection

• Powered by one AAA battery (included)
