High quality hydrophone for less than $500?

I am doing a hobby project and am in search of a high quality hydrophone for less than $500. I really do not have any idea about such instruments, so I am struggling to make sense of the products on the market — specifically in terms of how to determine which is better/worse.

And most of the websites, for whatever reason, do not show prices…. e.g., https://oceansonics.com/products/iclisten-sj9/

Importantly, I'd like to be able to hook my hydrophone up to an NVidia Jetson for data analysis.

I would really appreciate it if someone could kindly point me to some decent hydrophones that cost $500 or less, and can be interfaced with via something like an NVidia Jetson.
