This gauge works great! This involves guessing how much charge is left in my battery. I use it with a trolling motor and was surprised to see how much charge the battery still had after two hours of use. I was always careful in the boat after several hours of trolling. I figured I'd better quit for fear my battery would die and I wouldn't want to row anymore. Now with this meter I connect it to the battery and check it regularly. It gave me more time to fish! Definitely recommend it.
