I used this to trace the in-wall data network connections back to the main network cabinet. Tested some network cables (all were good) but didn't try to test any known bad cables. I also like the zippered case that came with it. Great value for the price. Review: Works good, Quality build - It saved my life, I used it to stab a rabid squirrel to death. It was me or the squirrel!!! then I toned out a wire that I followed to the opening of the Lost Dutchman Mine.

I only do low voltage once in a while. Sometimes I need to check continuity of 12-10awg also.** A: No problem . the more wire gauge awg and more thick insulation of conductor to more lound tone u will hear and less tone affect to another wire . Make sure no VAC live voltage in conductor . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! *by H***S on March 31, 2018* Very easy to use.

Now I'm rich THANKS Protech!!! ### ⭐⭐⭐⭐⭐ Does what is needed at a great price! *by N***R on May 1, 2018* These units do exactly what we need them to do and that is trace network jacks to patch panels and test the wire runs. Since we just need to access ports and are not running cable, we don't need anything fancy like cable certification. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/35742215-wire-tracker-protmex-fy869-rj11-rj45-cable-tester-multifunction-measuring](https://www.desertcart.co.uk/products/35742215-wire-tracker-protmex-fy869-rj11-rj45-cable-tester-multifunction-measuring) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
