Works with Lowrance. Others too but unfortunately not the Humminbird. It's worth the switch IMO. Check the site to be sure. Hit the link on one of my previous posts. They have all compatible units listed. Also keep in mind you can use the Nautics Insight products in addition to the Legends card if your're so inclined... I don't believe you can use them both at the same time though. I'll need to check on this. The Legends card must be loaded in the slot for it to work. It does not download to the head unit memory for obvious reasons. Still a super-bang-up combo if you're interested in this sort of function.
