I am looking to upgrade from my Humminbird Matrix 17. We fish on a pontoon. We mainly troll for crappie, stripers and hybrids on exclusively on main lake area of the Rez. I would like the fish finder to have GPS and a lake map. The Matrix 17 is ok but without mapping makes it hard to find the ledges and channels. I have been thinking (and lusting after) about a SI unit (898 and 998) but have had a hard time pulling the trigger based on price.

I am looking at a Lowrance Elite-7 HDI Combo 83/200/455/800 or a Humminbird 898.

Recommendations on these or are there better choices?

Thank you.
