Continuity, wire map and length are three different instruments in one word · review
A tester that reaches beyond network leads to USB, FireWire and coaxial, and whose contents list holds a case and an adapter and no remote unit.
The bottom line The broadest range of connectors here, and the only unit whose contents list has no remote in it. On a bench that is a fair trade; for a run in a wall it is the wrong instrument.
A five-in-one cable tester for common cable types from network and computer work, with connections named in the title for RJ45, 10Base, RJ11, USB, FireWire and BNC; for Cat 5 and Cat 6 network and ISDN connections; for USB A and B and six-pin IEEE 1394 FireWire; a connection test with indicator lights for eight individual conductors and the shield; a check for a short circuit, a wrong pin assignment and no connection; and a contents list holding the cable tester, a carrying case, a coaxial adapter and a manual.
Five-in-one, then RJ45, 10Base, RJ11, USB, FireWire and BNC. Six kinds named, on the same line as the number five. Both are printed here as published. Whether 10Base is being counted as part of the RJ45 entry or as its own is not something this page decides, and it is not decided here either.
Eight conductors and the screen. The same nine-way count as one other unit on this shelf, and on a shielded lead it is the ninth that fails quietly while everything else passes.
The contents list is complete and short: tester, case, coaxial adapter, manual. No second unit. That settles what this instrument is for. It is a bench tester for leads that can be brought to it, and the wide range of connectors it accepts is exactly the range of leads that live in a drawer rather than in a wall.
Work out whether the cables come to you or you go to them. This tester assumes the first, and nothing in the box changes that.
Priced from 50 € to 67 € across the German, Italian and Spanish Amazon stores the day this page was checked.
It is stocked on the American Amazon store as well, in that country’s own currency. The range above leaves those out: it counts euro stores and no others.
The French Amazon price runs past 1.6× the cheapest store. A gap that size normally marks a reshipper and not a seller in the country, so that listing stays out of the range above.
In the British Amazon catalogue with no live offer against it: the reference exists, nobody is filling it.

| Tester type | A continuity tester with indicator lights — the third bullet gives a connection test with lights for eight individual conductors and for the shield, and the fourth names the three faults it checks for. There is no screen and no distance measurement anywhere on the page |
|---|---|
| Connector types accepted | Six kinds are named in the title: RJ45, 10Base, RJ11, USB, FireWire and BNC, while the badge on the same title says five in one. The first bullet gives Cat 5 and Cat 6 network and ISDN connections, the second gives USB A and B and six-pin IEEE 1394 FireWire, and the contents list adds a coaxial adapter. The count in the badge and the count in the brackets are both printed here as published |
| Wire map detection | Yes — the third bullet gives a light for each of the eight conductors and one for the shield, and the fourth names wrong pin assignment among the faults |
| Split pair detection | Not published on the listing — the three faults named are a short circuit, a wrong pin assignment and no connection, and a pair that is continuous but wrongly twisted is none of them |
| Length reporting | Not published on the listing — no distance and no measurement appears in the title or in any of the five bullets |
| Tone and probe function | Not published on the listing — no tone generator and no probe is named, and the contents list holds the tester, a carrying case, a coaxial adapter and a manual |
| Remote units supplied | Not published on the listing — no remote unit is named in the title, in any bullet or in the contents list, which holds the tester, a carrying case, a coaxial adapter and a manual. Every other unit in this group states one |
| PoE detection | Not published on the listing — power over the network cable is not named in either direction anywhere on the page |
| Power source | Not published on the listing — no cell type, no cell count and no note about cells being supplied appears in the title, in any bullet or in the contents list |
| Amazon reference | B018EAEF4E (same reference on 6 Amazon marketplaces) |
| EAN | 0766623780094 |
The ability to test a run that is already installed. A remote sits in the socket at the far end and answers for it, so one person can check a cable that disappears into a wall. Without one, both ends of the lead have to reach the instrument, which means a patch lead on a bench rather than a run through a building.
Because the failure is the same failure: a conductor that does not reach the other end, or reaches the wrong pin. Those leads are usually thrown away rather than tested, and a unit that checks them turns a drawer of unknown cables into a small pile of good ones and a smaller pile for the bin.
continuity tester · RJ11, RJ12 and RJ45 · ISDN and Cat 6 to Cat 8 named · four named faults · lights for eight conductors on the remote · no power source stated
A continuity tester that names the four faults it looks for one by one, and never says what it runs on.
Best for: A house with both telephone and network wiring in the walls, where a single tester should cover the older sockets as well as RJ45.
≈ 11 €
continuity tester · RJ11, RJ12 and RJ45 · separate lights for pins 1 to 8 and for ground · shielding scanned automatically · scan speed low or high · 9 V block, not supplied
A two-piece tester that gives ground its own indicator alongside the eight pins, scans the shield automatically, and lets the scan speed be set.
Best for: Shielded leads and shielded sockets, where whether the screen is actually connected is as much a question as whether the eight conductors are.
≈ £16 / 14 €
multifunction tester with an LCD · RJ45 · Cat 5e, Cat 6 and Cat 6a · PoE to af and at · loopback · cable tracing ruled out in writing · voltage described two ways
A screen-based RJ45 tester whose last bullet states in writing what it cannot do, and whose second and sixth bullets disagree about what its PoE test measures.
Best for: A network with powered devices on it, for a buyer who wants the limits of the instrument written down before it is ordered rather than found afterwards.
≈ £35 / 39 €
