Coaxial Cable Tester Scout Pro 3 - Versatile Voice, Data & Video Test

In this review the Scout Pro 3 Coaxial Cable Tester is examined from the perspective of a tradesperson who needs reliable verification of voice, data and video runs. The bottom line: this kit is for technicians and installers who need a single handheld tool that tests RJ11/12 voice lines, RJ45 data jumps and F-connector coax, and also detects Power over Ethernet. The most compelling reason to buy is its combination of wiremap diagnostics, PoE detection and multiple remotes that let a user identify and verify runs quickly on real jobsites.

Key Features

• Versatile connection testing: Tests RJ11/12 voice, RJ45 data and F-connector coax so a single unit covers common voice, data and video cable types on site.
• PoE detection: Identifies and tests Power over Ethernet including PoE and PoE+ which streamlines troubleshooting of powered network devices.
• Comprehensive wire testing: Wiremap checks for miswires, split pairs, shorts, opens and shield issues to confirm correct terminations before handoff.
• Extended cable length measurement: Measures up to 2000 ft so installers can locate faults and estimate run lengths without additional tools.
• Complete testing kit: Ships with a self-storing main remote plus remotes #2-#6, coax adapters and RJ11/RJ12/RJ45 jumpers for immediate field use.

Who It's For

The Scout Pro 3 is aimed at network installers, AV technicians and facilities maintenance staff who need a dependable multi-function tester for mixed cable environments. Its blend of coax, RJ11/12 and RJ45 testing plus PoE detection makes it useful for jobs where voice, data and video are present and for validating new or repaired runs.

It is less ideal for someone only testing a single type of cable on a tight budget or for field technicians who require advanced time-domain reflectometer features beyond length estimation; those users may prefer a more specialized or higher-end certifier for enterprise cabling certification.

Pros & Cons

Pros

• Wide test coverage: voice, data and video connectors in one portable unit.
• Practical PoE detection that speeds identification of powered ports.
• Complete accessory set and carrying case allow immediate deployment on jobsites.
• Backlit display and clear wiremap results improve usability in low light.

Cons

• Some users report mixed compatibility with certain shielded CAT6 terminations, so verify with your specific cabling before relying solely on it.
• The kit does not include an analog probe for tone tracing, which is sold separately if you need active cable tracing.
