I have a 1199 and want to get a Lake master chip. I looked on Humminbirds website and it does not list any of the 99 series units as compatible with either the Lakemaster or Lakemaster Plus chips. I assume because they are not considered legacy products.
Can someone please confirm which Lakemaster chips are compatible with my 1199 series unit? Also is the Plus version worth the extra money to get the aerial overlay?
