Can we talk about that $120 cable tester I bought that barely worked?
I picked up this fancy digital cable tester from a supply house in Orlando about 6 months ago. It was supposed to check alarm cables for continuity, shorts, and even tell you the distance to a break. Cost me $120 flat. First job I used it on, a simple 4-wire run for a door sensor, it said the cable was fine. But when I hooked up the sensor at final, nothing. Spent 45 minutes re-checking every connection before I got my old analog tester out. That cheap meter found a broken wire inside the wall in about 10 seconds. The fancy one never showed it. Now that thing sits in my truck, and I only use it for a paperweight. Anyone else get burned by a tool that promised way more than it delivered?
