Chips for X-15, Which One?

[Wallygetter]

I've been trying to follow all the posts on this subject but still haven't come up with conclusive answers. Which chip is the best one for the GPS mode of the X15, I would like to purchase some this week but am still undeceided which way to go. Thanks to all who reply in advance. Wallygetter.

I am waiting for Lakemaster and Lowrance to get it together myself. I have 2 Lakemaster maps and like them the best for what I use them for. As soon as something happens with Lowrance ( like a free software upgrade ) I will download my maps to the MMC cards. Hope this helps. JJ
