Have several chinese models around the house and boat which have served the purpose but now looking to get something better. I want to be able to use it for automotive, mechanical, hvac, and electrical component testing (diodes, resistors, etc). An all-around quality piece that will be my "go-to" multimeter. Any recommendations? Doing initial research and I have a headache. A very large range of prices, models, features and opinions. What multimeter do you use troubleshooting boat/electrical issues and what feature do you find more useful than you thought it would be?
