I had the Targa 18 with full windshield. I would consider it a family boat first, fishing boat second. Good on big water - dry ride. The Deep V17 will be more of a fishing boat.
I believe that Tracker dealers 'must' deliver the boats with the standard electronics on them, or possibly upgrade to a better HBird. If you want something else, on the trolling motor, they can do that. If you want to replace the HBird on the console with same a Garmin or Lowrance unit, you probably need to do it after the sale. Not positive on that though.
Same on the trolling motor, you may be able to upgrade to a better unit, but not go to a different mfg.
