What genec said. Mine is analog and like me, has no memory. I just use it for running and watch the red line.

I have the FL10. It comes in 3 cone sizes and also a dual frequency transducer is available. I have the high speed transducer (19*), but it is about the size of a old timey flat iron. Throws a good rooster tail too. Mainly, I trust it's readings. Most times old tech is good stuff. We both know that.
