Slide this ruler across the surface of plans, maps, and blueprints and read the measurement on the digital display in one of 111 different scales including inches, feet, yards, miles, centimeters, meters, kilometers, or a scale you define. Ruler also calculates area and volume. Use the Electronic Ruler Cable (sold separately) to transmit measurement data from the ruler to your PC.

Hold on to the large, rubber-coated handle while carrying these tape measures. Use them outdoors and in dirty environments—an open reel allows dirt, sand, and other debris to fall away. Blades are coated to resist scratches, wear, and corrosion.

Pointed-hook tip grabs the edge of an object or drives into wood.

Loop tip hangs on a nail or stud.

Fiberglass blades are flexible for measuring curved surfaces, nonconductive for work near electricity, and corrosion resistant for use in harsh environments.

Steel blades are more rigid and durable than fiberglass blades.

These reliable tape measures include a calibration certificate traceable to NIST stating they have passed a test for accuracy. They have a loop tip that hangs on a nail or stud. The blade and case are coated to resist scratches, wear, and corrosion.

Measure distances over 35 ft. The case on these tape measures is vinyl coated for scratch resistance. The blade is coated or chrome-plated to resist scratches, wear, and corrosion. Chrome-plated blades are more durable than coated blades.

Loop tip hangs on a nail or stud.

Fiberglass blades are flexible for measuring curved surfaces, nonconductive for work near electricity, and corrosion resistant for use in harsh environments.

Steel blades are more rigid than fiberglass blades and are coated for corrosion resistance.

Easily spot the brightly colored case on these tape measures around your worksite and in your toolbox. The blade is coated to resist scratches, wear, and corrosion.

Keep your phone in your pocket and your hands free—these smartwatches perform a variety of functions on your wrist. They connect to Apple and Android phones via Bluetooth, informing you when calls, texts, and other notifications arrive. Designed for harsh environments and rugged use, they meet military standards for resistance to hot and cold temperatures, shock, splashes, and submersion in up to 100 meters of water. These watches have a compass and GPS for tasks such as navigation, tracking and saving location coordinates, and calculating the area of a location by walking the perimeter. With weather and elevation monitoring, you can set the rate of barometric pressure change that will trigger a storm alert. These watches track health and fitness metrics over time, including heartrate, blood oxygen levels, and exercise. They have a solar battery in addition to a rechargeable lithium-ion one to extend the time between plug-in charging.

These navigators give clear directions for safe and easy driving. Maps on the color display have easy-to-read labels, and spoken turn-by-turn directions help you keep your eyes on the road. Navigators give safety alerts for potential dangers up ahead such as sharp curves, speed changes, and school zones. They include a suction cup mount that attaches to your windshield or another smooth, flat surface.

Navigators with a power/traffic cord access real-time traffic data to give you alternate route suggestions when appropriate.

Navigators with Bluetooth connectivity link with smartphones for hands-free calling and notifications. When synced with a compatible app on your phone, they’ll give live traffic and weather reports. They also connect to Wifi networks to wirelessly update maps and software. These navigators respond to verbal commands—adjust their settings while keeping your hands on the wheel.

Navigators for trucks suggest the best routes based on your truck’s size, weight, and contents. When you switch trucks, it’s easy to update your profile with your new vehicle’s dimensions and cargo. These navigators alert you of steep grades and upcoming bridge heights, and contain a directory of truck stops and repair locations. 7-in.-wide navigators show nearby loading zones and storage docks as you approach your destination.

Freestanding and adhesive mounts secure to your dashboard, and clip-on mounts attach to an air vent, so they’re useful in states where mounting a GPS to your windshield may be illegal. Freestanding and clip-on mounts are easily moved from one vehicle to another, while adhesive mounts are permanently installed.

Measure and track GPS satellite data in vehicle fleets, electronics, precision agriculture, and other applications. For fast and accurate navigation updates, the antenna and receiver connect to multiple satellites at a time. With access to real-time data from the Federal Aviation Administration’s Wide Area Augmentation System (WAAS), these sensors track positioning within three meters. They store configuration data even when turned off, so they don’t need to be reconfigured when you turn them back on.

Protected by a compact, durable, and lightweight housing, these sensors are good for use in tight spaces. When used outdoors, they’ll withstand splashes, rain, and snow. Place them on metal with the magnetic mounting base, fasten them directly to a surface through the threaded hole, or secure them to mounts (sold separately).

Connect sensors with wire leads to a terminal block or connector, or solder them to a circuit board. These sensors use measurement pulse output to precisely keep track of time intervals.
