Radio Control guys used them all the time,
for egs. to find the right propeller to match brashles motor and controller
not sure on the boat,
...warning...only for momentary measurement
you can't push 100 A ...u have charcoal in no time...
very short period of time.
The OP link is only 0-55A the one I linked is 0-60A. Its a 12v system regardless of RC, boat or caravan. The RC guys love them because they are so accurate. I don't see why you would be pushing 100A on either unit.
I read the manuals and researched the real life experiences on many boats. 2yrs later many many boats 24/7 no charcoal.
