Continuity, wire map and length are three different instruments in one word · review
A two-piece continuity tester with a light for each of eight conductors, one button, and cells that are not in the box.
The bottom line A plain and complete continuity tester for the fault that actually happens on a hand-made lead. What it will not do is find a lead in a bundle or say anything about a pair, and neither is claimed.
A network tester supporting RJ11, RJ12 and RJ45 connections and compatible with Cat 5, Cat 6, Cat 7 and Cat 8 patch leads, named for varied network environments; fault diagnosis with a remote unit carrying an integrated display of lights for the eight individual conductors and further check lights for the wiring of the lead; single-button operation in a compact battery-powered body, named for technicians on site; a build described as robust for hard use in network work; and a note that the unit is efficient, runs on two AA cells and that the cells are not supplied.
A light for each conductor, on a remote unit. Both halves matter. The eight lights say which conductor is at fault rather than that one is; the second box means the far end of a run that is already in the wall can answer for itself, with one person walking between the two ends instead of two people shouting.
The compatibility line runs from Cat 5 to Cat 8. What is being tested through those connectors is continuity and order, not performance. A lead of any grade can be checked for eight conductors arriving in the right sequence, and no lead of any grade is being measured against the limits of its category here.
Stated in the last bullet, plainly. AA is the useful part: they are the cells already in the house, unlike the nine-volt block another tester on this shelf asks for.
Decide whether the leads are on a bench or in a wall. Both work here, and only the second makes the remote unit the reason to buy.

The British Amazon store returned nothing at all, so the buy button there opens a search in that country rather than a page that would not load.

| Tester type | A continuity tester in two pieces — the second bullet describes a remote unit carrying an integrated display of lights for the eight individual conductors, with further check lights for the wiring of the lead. There is no screen and no measurement of distance anywhere on the page |
|---|---|
| Connector types accepted | RJ11, RJ12 and RJ45 — stated in the title and in the first bullet, which adds compatibility with Cat 5, Cat 6, Cat 7 and Cat 8 patch leads |
| Wire map detection | Yes — the second bullet gives a light for each of the eight conductors and describes checking the wiring of the lead, which is the order the conductors arrive in at the far end |
| Split pair detection | Not published on the listing — the page counts eight individual conductors and never mentions a pair, twisted or otherwise, which is the fault a row of lights cannot see |
| Length reporting | Not published on the listing — no distance, no screen and no measurement in metres appears in the title or in any of the five bullets |
| Tone and probe function | Not published on the listing — no tone generator, no probe and no way of finding one lead inside a bundle is named anywhere on the page |
| Remote units supplied | One — stated in the second bullet, which is what allows a lead already run through a building to be checked from both ends by one person |
| PoE detection | Not published on the listing — no reference to power over the network cable appears in the title or in any bullet, so nothing says whether a live socket can be checked before it is unplugged |
| Power source | Two AA cells, not supplied — stated in the fifth bullet, which names the absence of a mains connection as the reason the unit suits places with no power available |
| Amazon reference | B0C6XJDSTX (same reference on 5 Amazon marketplaces) |
| EAN | 4262390151014 |
It names the fault. A unit that shows one light for the whole lead says something is wrong; eight lights say which conductor is missing or which two have swapped places, and that is the difference between recrimping blind and recrimping one end. This tester gives the eight, which is the ordinary arrangement at this level.
No. The line describes which leads fit the sockets and get their conductors checked. Confirming that a run performs to the limits of a category is a measurement against a standard, made by a different instrument, and nothing on this page claims it.
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 · RJ45, RJ11, USB A and B, six-pin FireWire and coaxial · lights for eight conductors and the shield · three faults named · case and coaxial adapter supplied · no remote listed
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.
Best for: A bench or a workshop drawer of assorted leads, where the network cables are only part of what needs checking and everything is within reach.
≈ $40 / 50 €
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.
