I unfortunately spend 30-40 hours a week selling these units to people. *Right now, today, the Lowrance 337 is far and above the best unit on the market. It's base map has twice the detail as Garmins, It's sounder/fishfinder has way better display and detail, the screen resolution is much higher and it's daytime viewing is superior. The 332 is also a very very good unit. I get any of the at a nice discount from Lowrane or Garmin and I would not consider anything but a 332 or 337...... LOL,,,and no I do not work for Lowrance..But,I sell them at a West Marine store.
