Saturation Diving Best Gear & Tier List

12 items ranked · confirmed effects only · checked 2026-08-30

How this list is ranked

Saturation Diving publishes no gear statistics: there is no public damage, speed or price data anywhere — official or community. So this tier list ranks gear on what is actually confirmed: the in-game monster log's warnings (which tools anger which monsters), official badge requirements (what the developer considers an achievement), and documented in-game behaviour. Anything unconfirmed, like the community-mentioned Cobalt Pick, stays off the list or is flagged — we never invent numbers.

Tier S — Define your survival

The purchases that change whether you come back up.

Tier A — Strong picks

Confirmed value in co-op, economy and defence.

Tier B — Double-edged light

Useful tools with a built-in downside the monster log warns about.

Tier C — Situational & late-game

Buy them for the badge, the lore or the look — not the meta.

The one rule the tier list hides

Light is a weapon that aims both ways. The Flashlight, Flare and Flood Light all rank lower than their obvious usefulness because the monster log confirms the Mothray Eel hunts light sources — in the deep sites, knowing when not to shine is part of the gear skill. That is also why the suit upgrades rank S: darkness and stillness are the real endgame.

Plan your purchases with the upgrades & best order guide, meet the creatures these tools fight on the monsters list, and see how the badge requirements line up on the badges page.
