Recently I've been asked to do more and more cable troubleshooting as part-time work. I don't want to spend more money than I have to, and I'd like to purchase the tools gradually over time as justified by the work I'm getting.
Can you please recommend a minimum set of tools (and suppliers/vendors) for someone who occasionally goes to a customer's site to do trouble-shooting, including cable trouble-shooting? I'm hoping to spend in the range of $500 altogether, not $20,000. Am I dreaming? For example, I've found a cable certifier at http://www.discount-low-voltage.com/Tools-Testers/Testers
1. Crimping tool, including RJ45 cable ends - got it
2. Cable tester - got it, but I need a better one
3. Cable certifier
4. Toner probe
5. Punch down tool
6. Battery voltage testing tool
7. What am I missing, that would be in the category of an "essential" tool for someone in this business?
