I would suggest a GPS is a vital feature on all sonars.
Pretty soon you won't be able to buy a unit without one.
You need it to run maps, you need it to mark good spots and return to them, to mark hazards so you don't hit them next time you are out, you need it to know where you are (versus where you think you are) on unfamiliar lakes.
I would always recommend this as one of the key features to look for and have on your sonar unit.
