Initial Thoughts

It’s rare to find so many solutions all packed into one tool. The Klein Tools Scout Pro 3 Tester Starter Kit makes it even easier for professionals to test VDV cables. You can test voice (RJ11/12), data (RJ45), and even video/CATV (coax F-connector) cables.

Klein seems to have taken user feedback into account when designing this kit. They increased the size of the backlit display and even simplified the user interface with more direct-access buttons and easy access to settings.

Key Features

The Klein Scout Pro 3 Tester Starter kit replaces the older Scout Pro 2 model. The new Scout Pro 3 lets you test terminated voice, data, and video cables with clearly defined results. It tests cable lengths up to 2,000 feet (same as the Scout 2), but features a larger, backlit LCD screen with a simplified interface. It makes it even easier to test for open, short, miswire, and split-pair faults.

Using the included LanMap and CoaxMap location remotes, you can test multiple cable runs in a single step. The remotes store away inside the base of the unit.

For those already working with Klein’s Analog Probe, you can tone test cables, wire pairs, and individual conductor wires.

The Klein Scout Pro 3 Tester includes a voltage warning and shield detection. An auto-power off feature saves battery life. Speaking of batteries—with a 9V battery, you can expect to get about 50 hours of runtime.


The Klein Scout Pro 3 Tester Starter Kit retails for $89.99. It comes with a 2-year warranty, and you can pick it up from a variety of online and B&M locations. The kit comes with the Klein Scout Pro 3 Tester, one self-storing remote, five LanMap RJ45 locator remotes, five CoaxMap F-connector locator remotes, a coax F-connector, a manual, and a 9V battery.
