Any thoughts on one versus the other? I was told the Vessel View was much cheaper than the Smartcraft Guage when adding to a new boat order. The salesman says the Vessel View will provide all the same data BUT it isn't right there is front of you. Any thoughts on one versus the other? I was told the price difference was roughly ($250 Vessel View Installed vs $900 for a SmartCraft Guage to be installed). Any thoughts?
