I will be using a 997 c SI. If I understand correctly I will have to remove the piezo unit(s) from compatible transducers.
Herein is my problem. I have some used transducers, a couple old Humminbird TCR 101s, a couple Eagles and one that I cannot identify. It is older, says Humminbird on the mount, but has a round 7 pin plug. Here are some pictures and if you have any idea what it is or model I would sure appreciate knowing. I just hate to have to buy a new one and tear it up.
Thanks for looking.
I also posted this in a slightly different manner in the "General discussion" forum, and I'm hoping I didn't make a site mistake, If so - I apologize.
