We get lots of requests for our maps from Garmin and Humminbird users, unfortunately they only work in Lowrance since they allow us to build the maps for them. I have contacted Humminbird and Garmin and they have not been interested.
If you want the lowest cost quality Lowrance to use for our maps the Carbon 9 is great if you can find a used one. if you want to know more my map maker Warren Parsons is very knowledgeable and will help you. 651-982-1401
