i recently put a helix 9si/di/gps g2, helix 5 gps/di and ultrex wit universal sonar. the 9 is working fine. i have the 5 hooked to the tm. no i know the di is not going to work hooked to US. my problem is no arches. if im on top of fish im just seeing blobs and specks that may be green or red. i have went to my big unit a sure nuff its fish. i have it on factory settings but i cant tell what i'm looking at in the water column. the speed, temp, depth, and bottom contour are all fine. any thoughts
