Topic: FNG looking for help with 998c si settings

[4stfire]

Greetings all. i bought my first bass boat, 2002 Ranger 195 VS, that came with a pair of 998's. I am brand new to using this type of technology and would like some help with basic settings. I have searched for "best settings" for the 998 and found a page, but the link is gone that it referred to. I've tried other searches, so much info on here but can't seem to find "idiots guide to fish finders". I have also reviewed the user manual, and while it explains some things it is still greek to me as i've never used one before. I look at the screenshots that some have shared and i can't for the life of me get mine to look anything like what you all are showing. I'm on Lake of the Ozarks in MO. Thanks in advance for any help.

Note: My list above always starts with Restore Defaults  ...

This is simply because regardless of how many settings you have changed and things are just not working with your settings choices - get back to step 1 with Restore Defaults and start from factory defaults again  ...

Thank you very much!! To be clear, are the frequencies set to 200/83 and 800? Do transducers go bad or deteriorate over time?

Default for the 2d Beam Frequency setting (under the Setup tab) is 200kHz  ...

Default for the Side Imaging Frequency setting (under the Setup tab) is 455kHz  ...

Transducers can become weaker or even lose piezo function over time  ...

Here is the 998 manual  ...
