I am looking to buy a new unit, was thinking 1198 or 1199. I currently have the 998 and I am not happy with the pixilated 2D sonar. It also has issues with reading the wrong depth when I get a strong return and have a double echo. I just want to make sure these units dont have the same issues before I purchase one and find out the hard way again. Thanks in advance with any feedback you can share.
