Not sure which tester you need? Start here
- Just need continuity & wiremap? A basic tester or tone-and-probe kit finds opens, shorts, and miswires fast.
- Signing off a data job? You likely need a certifier that produces pass/fail reports to TIA/ISO limits.
- Tracing cable in a bundle or wall? Pair a tone generator with a probe — no certifier required.
- Working with fiber? Look at inspection scopes and power meters, not copper testers.
