After installing the 7.080 update my unit seems to be working other than while in simaltor mold theres no 83khz.using the unit on the water the 83khz works.(imo) in 2d mold the 200khz doesn't perform as well as it did with my previous version.the 83khz ,well I'm not sure right now.the only 2d view that I think I can get by with,for now would be the 200/83 mold,and imo its not all that great but its the best for me.this picture is from the 200/83
