This is a great package for the money. My Ranger (Floor model) was purchased from Cabelas with the same unit flush mounted. Ranger epoxied the HDI transducer in at the factory. I can get clear sonar and down scan at 60 mph.
Mind you the GPS is a little sluggish but the 2D CHIRP and down scan are very good especially for the price of this package. We have the same deal but you won't pay sales tax and I can ship it for free.
