The Hook-2 units are going to be a great product for the cost. With the Triple Shot units, you will have Downscan, Sidescan, GPS Mapping and Sonar. You can’t beat the price of the new Hook2 4-inch to 12-inch units for the features you get. However they are stand-alone units so you will not be able to network them together like you can HDS units. The options that require the Lowrance network will not be available on the HOOK. But they fit in very well if those things are not a have to have. Lowrance is going to sell a lot of these units!!!
