Get a jump start and don’t ever worry about it again. I got a Goolo 2000 for $100. Weighs 2lbs and will jump dead diesels in the dead of winter. While I never have had to use it yet, I used it on a guides boat that we met at the launch. He had a 300 or 350 Verado, not sure which, and his battery was so dead it wouldn’t even try to turn the engine over. We hooked my goolo waited a few seconds and he hit the starter. Instantly fired up. I lent it to him for the rest of the evening, and he dropped it off to me later that night. Said he had to use it 3 more times. Also something to think about if you want all those locators is to turn your brightness down one number. It will reduce your power compsumption. On my helix 15 by turning the brightness down to 9 from 10, it reduces the power draw by over one amp.
