i just got the lms-480 and love it, i also got the navionics hotmaps which its not to bad but is there another chip that has a little bit more detail like it shows small pockets and stuff. but they are coming out with a new hotmaps chip i might just wait till it comes out and see what it is all about

Navionics has a pretty good trade in setup. usually around June-July if their card has been updated you can send it back to them and buy the new updated one and you will get a small refund towards. Check out their website for more details. I realize this might not help right now but will help if you are thinking of getting another chip in the future.
