This brief guide will let you know where to find the Scanner Room Fragments in Subnautica.
You will need to make your way southeast and south, starting from the coral tube sticking up out of the water. Keep moving until you reach a scattered wreck in the grassy plateau biome.
It is recommended to have a sea moth, a sea glide, a high capacity 02 Tank, and you will also need a scanner. The only threat you will encounter in the grassy plateu’s is the sand shark; you can easily avoid them or kill them using a knife.
When you search the wrecks, you have to mostly search around the outside of the wrecks for scanner room fragments.
After that, you will need to start from it and head between southwest and west until you reach another wreck.
Starting from the coral tube, you will need to head northeast or 1 in half bumps to the right of northeast until you reach a scatter-type wreck.
You have to head north from that scatter wreck until you reach another large wreck.
You will need to head about 2 in half bumps to the right of the south or between south and southwest, starting from the coral tube
It is recommended to have a sea moth with an mk1 or mk2 depth module, a sea glide, a high capacity 02 tank, and a knife.
The main threat you will encounter in the Grand reef is the warper which can warp you out of your vehicle. If it does, you can either run from it or deal enough damage until it warps away from you.
There’s also a chance you might see a ghost leviathan, it shouldn’t be near the wrecks, but if it is, you must keep your distance from it until it goes away.
From the first grand reef wreck, you have to head southwest until you reach the second wreck in the grand reef.
