Has anyone used Lowrance's new Mark/Elite 4 series with HDI? I know it was just announced in December and just released last month in January. I've been looking for a fishfinder and was going to go with a Mark 4 with just sonar and gps, but I did really want down imaging as well. Then I stumbled upon the new HDI series and it seems like quite a bit of technology for a decent price ($229/$299). It has all three features that I want but was wondering if anyone had hands on experience yet?
Also, while I'm on the topic and don't want to create a separate thread, can anyone tell me if this is the type of battery I would need to use for a fishfinder? It is from BPS (the 12V/7.5 Amp version). This is my first time installing/using one and it will be installed on my new kayak so I just want to be sure I am getting the right items.
