Pulled the trigger on a new HB 598ci HD over the weekend. Can't wait to get out on the water and test it out. Any advice on initial settings? I have never fished with a fish finder like this. My old boat had an old HB and I used an FL18 ice fishing all the time.
Nope, not a hockey player!
Connect the power cable to a 12 volt battery and run it in the simulator to get used to what the various menu changes can do.
Here are some videos to help with adjusting your Si unit and understanding what you are seeing:
