Best Diagnostic Tools for Rotorcraft Repairs

I’ve been going back and forth on which diagnostic tools are a must-have for rotorcraft maintenance. I’ve settled on the Honeywell BGA-9 and the Fluke 115 for quick electrical checks, but I’m curious what others are using. Any recommendations or insights on what’s been reliable for you in the field?

You can’t go wrong with the Honeywell BGA-9; it’s like the Swiss Army knife of diagnostic tools. For troubleshooting, I also recommend a good borescope — sometimes you gotta see what’s hiding in the nooks and crannies! Have you thought about adding one to your toolkit?

I’ve found that having a good battery tester can save a lot of headaches during troubleshooting. It’s surprising how often electrical issues stem from a simple power problem. Ever tried one of the Midtronics testers?
