I have some precious data on my Humminbird & zerolines chip… especially from treacherous uncharted lakes up in Canada. Tracks and contour data that is incredibly valuable. It can mean the difference between a 20 minute relaxed coffee-sipping run out to a spot or a white-knuckled hour taking it slow and trying to remember where that one rock was…
So my question is; are any of the big three graph manufacturers porting data from other systems? Being locked into one brand for your whole life seems really unappealing.
