These magnetic compasses provide your orientation relative to geographic points.

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 heart rate, 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.

Extend the blade to draw circles up to 144" diameter. The blade locks in place.

Navigate on foot with real-time GPS data. These handheld navigators access multiple Global Navigation Satellite Systems (GNSS) for accurate positioning even in remote locations and challenging environments such as dense forests. Use them to guide yourself to your destination, track and save up to 5,000 coordinates, and calculate the area of a location by walking its perimeter. They’re preloaded with topographic maps that include terrain contours, elevations, and bodies of water. Navigators have a color display, so it’s easy to read map details. Built for outdoor use, they stand up to splashes, rain, and snow.

To receive email, text, and call notifications on these navigators, link them to your smartphone via Bluetooth. Connect them to a computer with the included USB cable to upload additional maps or offload data and files. For extra storage, insert a memory card.

Measure distance, level objects, and draft circles with one tool. A jack of all trades, these tape measures include a vial level and a compass for drawing circles up to 20 ft. in diameter. You don’t have to crimp the blade to measure inside drawers and other objects—a top window shows the length from the tip of the blade to the back of the case.

Clamp these point-holding clamps, also known as trammels, onto a beam to create a compass.

Draw circles up to 24" or add Extension Beams for Expandable Beam Compass to create even larger circles.

Mount these sensors to robot arms, cranes, and vehicles to accurately track their movements. Also known as movement monitoring sensors for vehicles and machines, they hold sensors for attitude, angular velocity (rotation speed), and acceleration in a housing about the size of a hockey puck. As your machine moves, these sensors send data to vehicle systems and computers in real time using SAE-J1939 protocols. They can trigger on-board safety systems, which alert operators to dangerous conditions, adjust a vehicle’s path to avoid accidents, and keep machines working in safe zones. Use these sensors right out of the box with the standard settings or customize them for specific applications with the included software. They’re rated IP67 and IP69K to hold up to dirty, dusty environments and washdowns with hot, high-pressure water.

Combine these point-holding clamps with a pipe to create a compass that marks circles 1 1/2" diameter and larger. They're also known as trammels.

Check temperature, atmospheric pressure, and altitude wherever you go with these palm-sized barometers.

Slide this tool 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. The tool also calculates area and volume.
