I'm currently running the 07 Lakemaster's, is it worth the money to get the 09's??

Look at the new lake list to see if its worth it to you.

I'm just wondering if the detail has gotten better and where would the lake list be?

I was really impressed with the new navionics chip compared to the 09 lakemaster... i think you could run over to gander or cabelas and they should have the lake lists there...

google the name of the chip for the website, you can get a list of the lakes there.

From the website...

The All New 2009 LakeMaster® ProMap Minnesota Card is plug & play, which means you simply insert the chip into your Lowrance unit, turn it on, and the lakes automatically appear on your screen. It's that simple. The new MN chip is loaded with an amazing 770 total lakes with contours, of which 180 are high definition LAKEMASTER PROMAP lakes. That's over 50 new ProMap lakes. Just a few of the new updates for 2009 include: Shaded Shallow Water Areas for all ProMap lakes, Western Lake Superior in amazing 3 foot contours, Duluth Harbor and St.Louis River in 1 foot contours, and all of Kabetogama lake in 1 foot contours!
