I just finished installing my new 898c. After reading the manual many times, it still was quite a learning experience for my "first time" install attempt. Just a few comments: The supplied mounting bracket looks nothing like the one in the 898 manual on page 16 (unless I'm not looking in the right place). It looks more like the template in "Appendix A" (last page of the pdf manual). That sort of threw me off. Also, the drawings of the Transducer Knuckle, etc. on page 17 don't seem to match the actual supplied parts. The assembly and installation of the transducer, in my opinion, could be explained better. I think maybe some pages of an older manual (and drawings of former parts) were used to make up the new 898 manual.
I'm not trying to make a big deal out of this, but for a first time install, it was sort of a challenge for me.
Can't wait to learn and use my new unit. I'm sure it's a great purchase for me. Anyone else out there agree with my assessment? Thanks.
