I have the same performance on mine as the other guys I’ve mentioned. I will say however, that I NEVER, and I mean, never, leave for a fishing trip without an extra or two. They’re cheap, and you never know when a battery can fail you. I always disconnect my leads after fishing, well, two years ago, they somehow ended up touching when bouncing around in the Otter and the DCS drained my battery over a week or two.
Battery issues are the #1 customer service question/issue/complaint from Marcum, and all mfr’s use similar brands, so I’m sure Vex and Hbird field the same calls too.
