Default Cork liner in Airmar M-260 / M265

Does anyone know what the purpose of the 1/8" cork liner (inside the main fluid box) is for?

the cork liner helps minimize echo noise from the sidewalls of the in-hull tank.

Also.. if the M260 transducer stops working you can still use it as an ice chest to keep your beer cold..the cork helps insulate..

Can anyone tell me if any thin cork will work? I'm installing a used ducer in a new boat and don't have the cork. I'm thinking I can just buy some at a arts/crafts store? Thanks

Do not use the Arts and Crafts variety..it can deteriorate over time after emersion in the anti freeze etc.

Best to order the correct liner...it is made specifically for use in this tank.
