Useful now we have it but not sure its worth the heavy cost difference with "standard" transducers.
This has been my conclusion as well. Forward is great for anchorages, under 4kts, but it pretty spendy for providing only that.
I don't think there's a good solution yet for automating obstacle detection. Debris in the water is still best detected by keeping watch. Stuff just below the surface, though, that's a lot more challenging.
