Hi…a hall-effect clamp probe is very useful if you do anything with high current DC loads such as electric-hydraulic power packs, electric vehicles, etc. It is somewhat less important for low current DC loads where the typical multimeter’s 10A current shunt works fine.
I have a hall-effect clamp good for 2,000A that I use with my Fluke 87, but I love the little HF clamp for general use and plan to pickup a couple spares
