Having GPS built in your unit is far more important than target separation. You can use the unit on your boat all summer, mark spots that would be good in the winter. And how many times have you walked out on a lake and said.. I wish I could find where I was last time, now you can. There are times when one hole will out produce all the rest..now you just waypoint it and it's there forever. If you are going to spend $500 on a fishfinder get one that will find you some fishing spots too.
