I think what you're describing is more a difference in market than a difference in what the devices could be useful for. And I get that. You're going to make a lot more money marketing to people who just plain can't throw yet, which is honestly the bulk of the disc golf population.Most disc golfers think they want a sensor to measure the actual flight of a disc on the course; I was in this camp for years too. But once people get a chance to use these products I'm not sure that's how it will shake out in practice.
Once a player has an established throw, is breaking that 500' barrier, is accurate enough to put that shot to use and score low.... the more fine applications become more important. Such as getting into a field and baselining the discs in your bag, that you actually throw, and getting confirmation that you're correctly throwing particular shots when you're doing work at home into the nets.
