Quick answer
PC Gamer reports an early sulfur spot about 120 degrees southeast of the Lifepod, roughly 200 meters away and around 25 meters deep, near Coral Crabs and past the Welcome Centre. Small pieces can be grabbed by hand there, while larger deposits need the Sonic Resonator. Subnautica2Hub lists Sulfur in Coral Gardens and Observatory Ruins at 0-450m, and Subnautica2.gg lists it as used in 4 recipes.
Field notes for Sulfur spending
Sulfur is small until it blocks safety
Repair Tool, Strong Acid fallback, and Advanced Wiring Kit can all pull from the same little stock. Spend it after the safety route is handled.
Keep repair ahead of upgrades
An upgrade can wait longer than a damaged vehicle or tool route. If Repair Tool is not stable, Sulfur should stay boring.
Do not use fallback acid by habit
Sulfur plus Gold can make Strong Acid in some routes, but Necrolei Cyst is usually cleaner. Save the fallback for when the cyst route is inconvenient.
First sulfur route
Leave the Lifepod with a clear errand
Head southeast rather than wandering every yellow glint. PC Gamer points to the open seabed near Coral Crabs, past the Welcome Centre, as a quick early sulfur spot.
Look for yellow crystal, not gold
Sulfur is a yellowish crystal and can be mistaken for gold. Check the rock pillar and nearby sand before you call the route empty.
Grab small pieces by hand
PC Gamer describes a few small pieces you can pick up without special mining. That is enough for the first Repair Tool job if you are not bulk farming yet.
Bring Sonic Resonator for bulk
Large sulfur deposits need the Sonic Resonator in current reporting. Once you have the tool, return for a proper stock run instead of treating every trip as an emergency.
Do not push into hot water too early
The same route sits near volcanic vents. PC Gamer warns against swimming farther northeast before heat protection. Take the sulfur and leave if you came for the Repair Tool.
