WTB - Lakemaster, Navionics or other - Minnesota

[MegaByte]

I have an older Eagle FishElite 320 that I am converting to a portable locator. My main use the BWCA in Northern MN. I also fish WI but I have the Lakemaster WI for Lowrance already. The "stock" maps don't show any depths on the lake I am looking for (Basswood in Lake County). I believe it takes the same chip as Lowrance.

Does anyone have an older Lakemaster Minnesota chip sitting around collecting dust? Actually, any brand chip that will fit the unit and give me something would be better than what I have.

Nothing like waiting until the last minute to find out its not going to work. Leaving Saturday July 7th so I need it asap. Buy, rent, borrow, freebie, whatever it takes.

Thanks
