Itโs commonly known that a longer level produces more accurate measurements than a shorter one. A 4- or 6-foot level (or longer) is likely pretty accurate across a span longer than the level, but itโs really just extrapolation and trust in your tool. Ideally, youโd have a level that was as long as the distance between the two endpoints of the work. Of course, thatโs not really practical, althoughย laser levels effectively do just that. Then again, a long level often wonโt fit in the workspace or is unwieldy for the job. Thatโs why tradesmen useย torpedo levels: 10- to 12-inch levels that are appropriate for tight spaces or smaller work. Torpedo levels come in several shapes and materials โ from inexpensive plastic to proprietary composites to aluminum in odd die cast designs, I-beam, or billet form. Today weโve got a unique take on the design coutesy of theย Kapro Torpedo Level with OptiVision.
Kapro has been making layout and measurement tools for thirty years. Headquartered in Israel, its American subsidiary, Kapro Tools, is in the small town of Lake Mills, Wisconsin.ย The company prides itself on its innovation which includes a unique vial integration and bubble/color definition. Are these ideas enough to make your current small level seem out of plumb?ย Letโs fire this torpedo and find out!
Key Features
Cast Body and Form
I mentioned that torpedo levels come in many shapes and materials, but the Kapro Torpedo Level must be unique among them โ at least in shape. Itโs cast aluminum body is reminiscent of Short Circuitโs Johnny 5,ย for all you 70s and 80s kids.ย In any event, youโll notice that the white body has a thick bridge around the level vial for strength, while the plumb and angle vial are at opposite ends.
A precision-milled bottom has a V-groove and rare-earth magnets. These features will be especially helpful to our electrician and perhaps plumber friends, even if us carpenters wonโt use them quite as much.
OptiVision and Rotating Vials
The selling proposition of OptiVision โ the red color of the level vial โ is that itโs up to 8 times easier to see than a traditional vial. Iโm not sure how you quantify that exactly, but anything thatโs clearer and results in great is accuracy is fine with me. It seems to work well with the Kapro Condor, so thereโs every reason to believe it will with this torpedo. We will literally see.
This vial includes gradient lines at 1% and 2% on the inside of the vial. I should note, however, that the โ1%โ and โ2%โ markings arenโt present. The website photos of this torpedo show one level without the markings and the rest with them, so itโs possible we just got an early sample.
Then thereโs the plumb vial which has no particular innovation. The rotating angle vial is probably as self-explanatory as it is potentially useful! The world of building and remodeling is more complicated than just level and plumb 90ยฐ angles, and thatโs where this vial, with 5ยฐ graduated markings, will assist us.
All three of the Kapro Red Torpedo Levelโs vials are acrylic, shock resistant, UV protected, and warrantied for life.
Accuracy
Have you ever found that your level isnโt accurate? Itโs not a good feeling โ and it probably didnโt result in accurate work, either! Most high-end levels today are verified accurate to 0.0005 inches per inch โ a remarkably tight tolerance. The Kapro is no different with a certification from the German VPA to 0.0005 inches per inch. It is a bit odd, though, that Kaproโs video claims itโs theย only level with that amount of accuracy. Iโm sure the folks at Empire, Stabila, and other companies would object, but it may be specific to the VPA process.
Two oversized, shockproof endcaps contribute to the Kapro Torpedo Levelโs unique look and protect the levelโs accuracy. I suspect they also provide a secure grip surface. Thereโs also a hanging hole in each end cap.
Performance
Heavy Metal
When I first got the Kapro torpedo level in hand, I was first struck by the weight. The cast aluminum body puts it on the hefty side. Of course, the heft also means itโs strong. In fact, I mentioned the bridge around the OptiVision level vial โ a feature that protects accuracy but beefs up the tool. So too do the shockproof end caps. Itโs something to keep in mind if you plan to carry this in your toolbelt โ youโll need a large pouch. And donโt count on being able to slip this into your pants pocket. Most torpedo levels are tapered or beveled in some ways to allow easy pocketing. It might not be a deal breaker for you, but the size and rubberized end of the Kapro will make this virtually impossible.
Seeing Red (In A Good Way)
I used this torpedo level on several jobs, including building the framework to re-skirt a mobile home, verifying its railing angles were within tolerance, and several leveling and angular tasks. Iโm happy to reportย that the plumb vial is a breeze to use. The angular vial rotation works very well, too. The star of the show, of course, is the OptiVision level vial. I must say, it is very easy to read with the red color creating a high contrastย that is clear to the eye.
ย
Whatโs Your Angle?
Despite Optivisionโs strength, there is a design oddity that could make the Kapro slightly harder to use than a traditional level. The OptiVision vial nests in the top of the level such that itโs visible from the top and only one side of the level. Effectively this makes the level have a front and back, whereasย most levels are reversible. I suppose you could make the case that because most rotating vial angle levels only have the angle gradations on one side to give it a front and back as well. But I use the level vial much more often. I find myself sometimes having to flip the level around. Itโs certainly no dealbreaker, but itโs worth a mention!
ย
The Bottom Line
The Kapro Torpedo Level is a tough layout tool with a couple unique features. The other side of the featuresโ coin means that the level is large and heavy. Itโll need a big pocket in your toolbelt and it wonโt slide easily โ if at all โ into your pants pocket. All the vials, especially the OptiVision level vial, are easy to see. But the nested design of the OptiVision vial means you might have to flip the level around to see it, which can be annoying in the middle of the job.ย If those couple quirks donโt dissuade you, the Kapro is not too shabby for $19.99 compared to peers with comparable features at $50 or more.
