Is a high-end unit like the Garmin ECHOMAP Ultra 2 worth it?

The ECHOMAP Ultra 2 126sv adds a 12-inch display, full Navionics mapping, and LiveScope live-scanning sonar, which is genuinely a different class of tool for serious anglers and tournament use. It carries a very high customer rating, but on a tiny review sample, and its price is roughly ten to twenty times that of entry units, so it only makes sense for anglers who will use real-time scanning sonar.
