HOW THE ZIP LEVEL IS THE WORLD’S ONLY BUBBLE FREE ALTIMETER
A bubble inside a hydrostatic altimeter can cause endless errors, which makes it useless. A half-inch bubble can cause your measurements to be off by an inch. If the tube gets stepped on, it can create a 5/8-inch bubble within minutes, while a snag can create a two-inch bubble. If you run it over with a minivan, you'll see a froth of microbubbles that can grow in a short amount of time. That’s why you need to keep the tube below the reservoir while it’s in storage and in use. The Zip Level is the only pressurized altimeter that makes storage and use much simpler, and it’s faster than lasers and bubble levels.
THE ZIP LEVEL HIGH-PRECISION ALTIMETER REPLACES ROTARY LASERS
The Zip Level can be set up in seconds, and you can get what you need by yourself in minutes. Just unpack it, turn on the power, read any deviations from a level plane, and pack it up. A unipod is includes with the device, so you can make measurements while you’re standing. With a single setup, you’ll have a vertical range of 40 feet over a 200-foot circle. And you can measure unlimited distances or elevations without the need for complex calculations. Unlike conventional levels, it won’t amplify errors with distance. And it never needs a factory calibration. It requires no indoor or outdoor line-of-sight. And because it’s both impact and water resistant, it can withstand years of rugged use.
