Contemplating a 360, based on a YouTube video I watched. I don't know very much on any of the new fish finders and I would like to upgrade to a SI type finder. Based on the video it appeared to be a good 360° image all around the boat. If it's a good choice for a once in a lifetime upgrade, other than the Garman Panavision, what's the general opinion of you more experienced on the higher electronics of the newer finders. I don't want to be buying a barely understandable unit. My wife will think I just spent a bunch of money for a finder that is too hard to interpret. If I can't understand setting it up for finding fish, it's only gonna make her belittle my choice If we aren't finding and bringing fish aboard, there would be a not so useful factor that would be hard to defend. Help needed out there...
