Found one. How useful is this at home? Is the main issue with interpretation?

That one is not going to be particularly useful at all. It's a linear probe, which means it's really only for imaging things near the skin. It's one-third of a typical set of probes: https://stanfordmedicine25.stanford.edu/the25/ultrasound.htm...

It's different from the MEMS-based devices this article talks about, which have the novelty of letting you do everything with a single probe. Though of course that comes with trade-offs.
