The EDC community is particular about what earns a place in their pockets. Titanium hardware, precision multitools, and machined accessories all go through plenty of scrutiny before they make the cut. Yet for all that attention to detail, accurate measurement is still largely a workshop activity. A full-size caliper stays on the bench. A rough estimate fills the gap. Something between the two has been missing.
TiCal Pro 2.0 is designed to fill that gap and makes a bold case for being the first pocket caliper you’d actually trust for real measurement work. It’s not trying to replace the full-size tool on your workbench, but to bring genuine vernier precision down to something that clips to your keychain, hangs from a cord, or disappears into your pocket.

What sets it apart from the usual pocket-tool crowd is a deliberate narrowness of purpose. There’s no bottle opener, no ruler on the back, and no attempt to make it busier than it needs to be. TiCal Pro 2.0 does one thing: it measures. Outer diameters, inner diameters, and depth, with jaws and a depth rod machined as integral parts of a single titanium frame.
One of the more practical details is the dual-scale vernier system. Makers who move between metric drawings and imperial hardware know the frustration of converting on the fly. TiCal Pro 2.0 carries both inch and millimeter scales simultaneously, synchronized so that a single glance gives you both readings at once. There’s no mental math involved and far less room for the errors that unit conversion can invite.
With a resolution down to 0.01-inch for imperial measurements and 0.1mm for metric ones, it’s built for the kind of small-dimension work that usually gets left to guesswork outside the workshop. The scales themselves are laser-engraved deeply enough to resist daily wear, which matters a lot for something that lives in your pocket. Shallow printed markings fade quickly; these stay sharp and legible through regular carry.
Precision tools have a tactile dimension that often gets overlooked. TiCal Pro 2.0 addresses this with a self-lubricating POM ball rail system that delivers a silk-smooth slide with no oil and no grinding. The damping is also adjustable with a standard T5H driver, letting you set the slide resistance to your preference so the jaw stays exactly where you put it, no locking screw needed.
The choice of Grade 5 titanium for the body is practical rather than decorative. It offers the strength of steel at half the weight and is corrosion-proof, shrugging off sweat, rain, and shop fluids without complaint. For a tool meant to stay on your person at all times, that kind of durability makes a genuine difference in how willing you’ll actually be to carry it.
Think about the moments when a precise measurement would’ve been useful. A screw that looks like the right size but isn’t. A 3D-printed part that fits almost perfectly but not quite. A watch lug you’re trying to match without guessing. A keyboard stabilizer that needs a bit of finessing. These are the moments where a quick estimate wins by default simply because the right tool isn’t close enough.
At 3.37 inches long and weighing only 37.6g (1.33 oz), it’s compact enough to clip to a keychain or hang as a pendant, always within reach but never in the way. Four integrated tritium slots add a subtle glow for low-light situations, and the tool is available in either Sandblast Titanium or PVD Black, two very different expressions of the same object.
None of that changes the fact that a full-size caliper will always offer more range and a longer measurement stroke. But TiCal Pro 2.0 isn’t competing with the bench tool; it’s filling the space where that tool never goes. Precision doesn’t always happen in a workshop, and this small titanium instrument quietly makes the case that it doesn’t have to.
