What Tool Should I Use To Measure DC Current Draw - Mike, on Dec 16, 2015 asked:

I am the owner of the White ACB (Aluminum Chamber Boat) boat that you did an electrical audit on a couple of years ago. My question is do you have a recommendation for a good multimeter to measure DC Current draw that will not break the bank? I want to understand the current load of different items on the boat for planning the size of the battery bank, trouble shooting, etc. Would one of the Fluke clamp on style tool be a good bet?

Here is the one I personally use: Blue Sea Mini Clamp Multimeter - AC/DC

Looking at amazon.ca, there seems to be plenty of less expensive options. Make sure the one you choose has DC amp range of at least 300 to 400 amps.

Let me know which one you buy and what you think of it.
