who has xi5 connected to depth finder?

I was thinking about getting the gateway for the xi5 to connect to my elite 7 ti. does anyone have any experience with how well it works? I have a hard time marking a structure and then going back and finding the dang structure by just steering the boat. In theory, with the gateway, i can just touch the spot on my screen and it will take me back to that structure. In real life though I am curious how accurately it can actually accomplish the task. Anyone have experience with the xi5 connected to your lowrance? Thanks.
