I'm getting real close to buying one, I don't have any other devices for it to communicate with so I don't see any need to get the G2N. I currently have the HUMMINBIRD 486 CI DI but the screen is so small and side imaging seems so much better. I'm just wondering what other people think that have it already or know something I should know. I would like to get a card with it also but there's more questions. Does that "smart strike" actually work? People are talking about a better transducer/upgrade? Should I get the swivel mount or just make it work? Which card is best; Lake Master etc.? Where's the best place to buy from; amazon etc.?
