I think you need to evaluate where you will fish to ensure that the HD is worth the extra money – i believe it’s ~$150. Each year I end up at lakes that I have never been to before and find that the HD with pre-loaded maps is a huge benefit. For example, in July when I was headed home from the Escanaba tour event Ranger asked me to stop in a dealership south of Wausau, WI and give demo rides for 4 hours on a flowage (sorry don’t remember the name). It was really nice to have a lake map pre-loaded on my hard drive of the 113 that I could pull up and use. Several folks that had 111’s did not have that map so Lowrance keeps adding more maps each year.
With that being said, I also have Lakemaster chips for MN, ND, MI, etc. and wouldn’t be without them.
Evaluate your situation and go with what will work the best for you!
Good luck with your decision!
