For those looking for these and having trouble, I found a location that I got a good number and only had the first Pressure Compensator upgrade for the Seamoth. I went to the Sea Treader's Path area hoping to find some, but found none near the surface area for it. I was discouraged, but on a hunch, dove deeper, and luck happened to bring me to the Sea Treader's Cave.

The cave itself has a bottom that is under 300 meters, but if you keep your Sea Moth near the top of the cave, it is easy to stay above 300. For diving, I used three High Capacity Tanks total and the Rebreather, and with that I had plenty of time to gather things before even getting close to out of air.

I ended up cleaning it out from one end to the other and came back with 19 Aluminum Oxide Crystals and some amount of Mercury (didn't count them, but I have a few now). Stash in nearby Cyclops, repeat. Also got a large amount of salt and other ores that way, with no predators once I found the cave entrance.

The beacon I left showing me where the entrance is shows up at -1464.0, -266.3, -444.0. Shot I took is dark because it was night when I came out, but the coords are there. Happy hunting!
