Hey guys, I recently got myself a Lowrance HDI Elite 5 for my hobie and was wondering if any of you guys had any tips on frequencies to use, split screen options, or anything you guys can think of to help me get better acustomed to my new unit. I've never fished with one before but I'm looking to get good! And become a fish slayer this coming summer!! I want to target big game fish

If you guys could leave some tips or links to good articles i would really appreciate it! Thanks!
