I’m running a Garmin 62st handheld for ice fishing with the last Garmin compatible LakeMaster chip. I live in the Keweenaw Peninsula of MI and while the chip has coverage for inland waters, it does not have coverage for Keweenaw or Huron Bays of Lake Superior itself. Other more popular great lake water, it does, such as Grand Traverse, Little and Big Bays de Noc of Lake Michigan and Saginaw Bay of Lake Huron for example.
The Garmin Blue Chart chip which would cover at least a portion of Keweenaw Bay has a 3 mile offshore limit but I don’t want to pay $160 for a chip that a) only provides partial coverage, and b) is needed for such a relatively small hole in my data coverage. The Navionics chip for the area would be great but doesn’t have compatibility with Garmin. Does anybody know if there’s any way to do a localized data pull and then convert Navionics data into something compatible with Garmin? Is there another solution that I’m overlooking? Any help would be appreciated.
But yes, I had already thought of that in the interim as coverage could and probably would be an issue with Huron Bay which is a bit more remote.
