In this guide, you will come to know where to find the Power Transmitter Fragments in Subnautica.
Starting from the coral tube sticking up out of the water, you want to head 1 bump to the right of northeast or 1 in a half bump to the right of northeast until you come across a wreck at the beginning/edge of the bulb zone.
It is recommended to have a sea moth with an Mk1 Depth module, perimeter defense, sea glide, and high capacity O2 tank, and you will need a scanner.
The main threat you will encounter in the bulb zone is the Ampeel; you should try to avoid it as best. You also have to avoid the bonshark or kill them with the survival knife. You can use perimeter defense against it to get it away from you.
Once you reach the first wreck, you have to look around on the inside and the outside seafloor for power transmitter fragments.
Once you finish searching the first wreck, you have to start from the first wreck and head about 1 bump to the right of the east until you come across a second wreck.
