The 3 in 1 Laser/LED/Pen is exactly that: a red laser pointer, a blue LED flashlight, and a retractible tip ballpoint pen; all wrapped up in one handy-dandy instrument.

The device runs on 3 AG-13 (LR-44) button cells, contained inside the upper part of the pen. It comes in a handsome two-tone metal case, which is tinted pewter and chrome.

The ballpoint pen writes in black ink, and the writing quality is similar to or slightly better than ordinary disposable Bic pens. I'm not a pen expert though, and I do not play one on TV or on the internet, so I'm not really qualified to rate this part of the instrument.


SIZE



Install the batteries first (see below), and then you can go to town.

To use the pen portion, grasp the barrel by the chrome ring in the center with one hand, and twist the writing-end of the barrel with the other, clockwise (as if tightening it) to extend the pen tip.
Perform the same action except twist the writing-end of the barrel counterclockwise (as if loosening it) to retract the pen tip.

To use the LED, press the lower button on the barrel and hold it in to turn it on; release the button to turn it off.

To use the laser, press the upper button on the barrel and hold it in to turn it on; release the button to turn it off.

This instrument comes with a pocket clip, allowing you to carry it clipped into a shirt or pants pocket, reducing the chance that you'll lose it when carried that way.



To change the batteries in this instrument, hold it so the laser and LED openings are facing the floor. Unscrew the two halves of the pen, and set the writing portion aside.

Tip the three used AG-13 or LR-44 button cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Stack three new AG-13 or LR-44 button cells on top of one another on a flat surface like a table or counter, button-end (-) negative facing up.

Lower the upper portion of the pen directly over the cells, and slide it to the edge. Place your thumb or a finger over the end so the cells just don't fall out and clatter to the floor when the pen passes the edge of the table or counter. Invert (flip over) the pen and your thumb or finger simultaneously, and remove your thumb or finger from the opening.

Screw the lower portion of the pen onto the upper portion.
There. Done with that.



This instrument is reasonably durable, but because it has a laser in it, I won't do the smack test on it. I know you love to see me break things, but ain't gonna happen today, folks.

Water-resistance is minimal at best. When the business-end was suctioned, air had no problems whatsoever passing through it. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of siamese cat pee (what - no cat box?), slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your pen to smell like seaweed or piss when you go to use it next. Besides, salt (from seawater or wee-wee) can't be very good for the insides.

The laser appears to have a wavelength of 645-650nm and an output power of just under 5mW.
This makes it a CDRH Class IIIA laser device.
It is properly labelled, with a laser warning sticker on the pen itself, and another laser warning printed on the back of the packaging it comes in.

The LED appears to have a dominant wavelength (where you would point to on a color chart) of approximately 475nm, which is just very slightly greener than the typical blue LED with a dominant wavelength of 470nm.

TEST NOTES:
I believe I purchased this on Ebay in mid-December 2003.
I have no links or pricing information to provide, sorry about that.

The package reads "MADE IN CHINA" on the back.
