I'd look to Mr Blevins' videos on the subject as well, but if you're hunting deep, the Hooks lack the frequencies to get the job done. I love my Garmin. Happily moved over from Lowrance. I have a striker 4 and an EchoMap. Echomap is about 2x as much, but has the ability to back up your waypoints and a slightly better interface. I would def go for the striker plus over the striker if you're choosing.
