Can't Unlock the Seaglide in Subnautica

The Seaglide is an early two-fragment mobility blueprint. Search the small wrecks and seabed routes in the Safe Shallows and Kelp Forest when the starting swim speed is holding back exploration.

LAST CHECK

ANSWER LOCK // QUICK RESPONSE

Scan two Seaglide fragments in the Safe Shallows or Kelp Forest, including their wrecks and small wrecks. Then craft the Seaglide at the Fabricator with a Battery.

SIGNAL CONFIRMED

BLUEPRINT DIAGNOSTIC // WHY IT ISN'T UNLOCKING

The Seaglide has its own two-fragment scan set. Scanning a Beacon or Mobile Vehicle Bay fragment, or finding the correct wreck without finishing the scan, will not unlock it.
