how much do they run for each lake?

thanks! LOL!  too expensive for me for just a few creek channels per lake, that I can find on my own. I  CAN see it benefiting someone who was just starting out.  The tank damns would be a benefit, as I dont know where a lot of those are.

Jeremy,

I got one to test out for Fork and used it last week for the first time. I was impressed with it. I feel like the accuracy of the creek channels is almost perfect and it showed me stuff I did not know was ther via other chips and paper maps I had used. Very easy to install and use and is compatible with Navionics and Boat Lanes. It also lets you customize colors you want to use for the features it shows. All In all I like it quite a bit. I run Birds front and back and have the InterLink and I had no issues when I downloaded it in both units.

i have one for palestine, and one for the tri-lakes(monti, sandlin, cypress).

i am not pleased. the one for the trilakes as it states on the chip ANd the package.. only shows routes on sandlin.

I wont buy another.

btw- Jeremoy, they are both for lowrance units, and you can have them if you really want to see them. they are useless to me now. i am back in humminbirds.

Cool...  Let me know where you catch the fish.....lol
