Redge, Yes I have an Off Set, but my GPS receiver is only 3' for my TM. You may not be aware but if you have the 360 hooked to an SI unit, you can use it for DI and SI. I have not set it up that way to see how good the images are. I would have to change setting every time I wanted to go back to my transom SI xducer ..... because as you know I only have one 998 on my boat and use a TS2 switch. But if a person had a bow and console unit that might be pretty cool. dj
