Combine a counter, feeder reel, coiler reel, and stand to create a wire, cable, and cord length measurer.

Counters measure material as you thread it through the internal wheels. These counters add and subtract. Mount them on a pedestal or floor stand (sold separately). Urethane-coated wheels are for PTFE-coated wire and fiber-optic cable.

Feeder reels hold material before it's threaded through a counter. Wind material around adjustable pins on the reel, or place spooled material on the 1/2" diameter spindle.

Coiler reels gather material once it has passed through a counter. These reels have a hand crank and collapse for storage.

Feed wire through the wheels inside the included counter to take measurements. The counter adds and subtracts. Wind your wire around adjustable pins on the feeder reel, or place spooled wire on the 1/2" diameter spindle. Gather it on the coiler reel once it has passed through the counter. Coiler reels have a hand crank and collapse for storage.

Urethane-coated wheels are for PTFE-coated wire and fiber-optic cable.

Roll these wheels along a surface to measure distances up to 99,999 feet. Choose 36" circumference and larger wheels for measuring uneven surfaces.

Style E operates on a nonreplaceable battery with a minimum 10 year life.

Record steps or miles while you walk or run.

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.
