Thread: Don't hate a forgetful feller.

I know I asked this before but I can't find it. I have a hummingbird 899 in route and someone said I should swap out the transducer. I will be mounting it at the console and it will have a transom transducer. Can anyone give me the specific one I should swap it out for? I will write it down this time

Should be a sheet of paper in the box telling about the swap out etc. Dont open the bag the ducer is in if your going to swap.
