I have a brand new 1198...not even one week old. The unit has and was tested on both Monday and Tuesday ( 4/11-12 ).
On Monday...fished 3 hours with unit....everything good. On Tuesday, everything good until about the 3rd hour into the day. My unit....not matter what screen I was on, locked on 1.6ft depth readout. Every now and then the unit seemed to try and find the correct reading. Now...as for everything else....it worked fine. I could see the depth by use of the depth lines or close byt reading still locked on 1.6 ft,
So, I called the fine folks at Humminbird Customer Service ...which they were very nice. They worked me through 2 restore(s) and one other deal to help my but NO luck at all. They said the only way was process of elemination. I had to anchor my boat, take all wires loose and trace transducer wires. I ru a 2 transducer system...or did. I use on top of the S I Ducer that comes with the unit...I also use the xnt 9 20. Well....I found the problem without having to send a 4 day old unit back into the alabama shop for repair....I have/had a short either in my leftover "y" cable AS SIDBY or my leftover Transducer XNT 9 20 from my 898. I don't know which one is bad but the problem fixed itself just as soon as I plugged the S I Ducer that comes with the 1198.
So...my question to all of you is....I run a Aluminum 18 ft War eagle... Can I use the XP 9 20 Shoot through the hull Ducer ? or should I go back with the xnt 9 20 ? OR do I need a two Ducer system.
What is the advantages and disadvantages of a single Ducer S I sysem or a 2 Ducer S I system. Which would best be for me and details. I know that the xnt 9 20 can be used running. Also, which temp sensor is used on which Ducer. Thnaks for your help folks.
