Let me break the trend here. I've been with Lowrance for about 15 years now. That is not a reflection on HB at all, just the brand I started with and other than some challenges getting connected to customer service on two occasions, I really like the brand.
I have HDS 12 at the console and an HDS 10 in the front. System includes side scan and down scanning as well as the sonic hub and the Sirius weather module. I love the new touch screens but as someone already mentioned, you need to spend the time to learn the user interface. While I'm not familiar with the interface on the HB systems, I would wager it is easier than the Lowrance models.
Good luck as you do the research and make your choice.
