After playing around with it, it’s nice when it works, in my kayak to work properly i need to paddle very slow, after all, it’s really good but the app need an update, it’s been a year right now with no update i like to see a fish alarm in the update, because you cannot keep your eyes on the screen all the time, it would be better If you can hear the fish alarm. Comparing to Deeper sonar they have an update almost every three months, i thing Garmin are to lazy to improve there App, nice hardware but the App need an update to work better. And why there is no information anywhere about the battery life cycle, because I need to know what I’m gonna do if the battery dead completely the lifecycle it’s finish I mean, do I need to throw it away if this is your answer that’s not good you need to have an option to change the battery when it’s completely dead like deeper sonar do, if you want to be competitive.
