What this is is a pen-style laser pointer that can be stuffed in your pocket or live in your briefcase. It emits a red beam with approximately 3.6mW of output power.

It comes in matte black finish body, with a matte silver color tailcap and nose.

Because this is a laser, you should not shine it into your eyes, other people's eyes, pet's eyes, etc. Just use a little common sense here, ok?

The emitted wavelength was spectrographiclly measured at 653.8nm, in the red portion of the spectrum.


SIZE



Point the front end at whatever you wish to point out, and hold the button at the top front of its barrel down for as long as you need the laser spot. Release the button to turn the laser pointer off.

Yes, it really is that easy.

This button has a tactile "click" sensation to it. This click may also be audible to the user in a quiet location.



To change the batteries in your laser, unscrew and remove the tailcap, throw it in the {vulgar term for feces}bowl, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the two used AAA cells out of the barrel and into your hand, and dispose of, recycle, or recharge them as you see fit.

Insert two new AAA cells into the barrel, flat-end (-) negative first. This is the opposite of how batteries are installed in most flashlights, so please pay attention to polarity here.

Screw the tailcap back on, and be done with it.
Aren't you glad you didn't flush away that tailcap now?

Current usage measures 27.3mA on my DMM's 400mA scale.



This is a laser pointer, not a flashlight meant to be carried around, thrashed, trashed, and abused. So I won't try to drown it in the cistern (toliet tank), bash it against a steel rod or against the concrete floor of a porch, let my mother's big dog's ghost or my sister's kitty cat spring a leak (uranate) on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

This product is properly labelled as to its wavelength and power output.

The Radio Shack catalogue number for this product is 63-1064.
O for Pete sakes...this is the same catalogue number as this laser pointer...oops!!!

TEST NOTES:
Test unit was purchased at a Radio Shack in Federal Way WA. USA late on the morning of 04-04-09.

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.
