Scale the Depths Guide Hub: Fish, Customers, Upgrades

Scale the Depths is live, small enough to learn quickly, and deep enough that a notebook helps. Steam describes the loop plainly: fish, scale, sell, repeat. The useful route is to catch a fish, scale it well, serve the right customer, spend money on the upgrade that fixes your current bottleneck, then push into deeper spots for secrets and treasures.

Last checked: May 30, 2026. Steam lists Scale the Depths as released on May 28, 2026. The store and launch announcement confirm four locations, 100+ fish species, customer favorites, upgrades, boats, hidden treasures, messages in bottles, environmental puzzles, Windows support, and macOS support. Exact fish names, values, tips, customer favorites, and puzzle solutions should be checked in the current build.

Current Status

Fact	Current read	Player impact
Release	May 28, 2026 on Steam	The game is live, so current-build notes matter
Core loop	Fish, scale, sell, upgrade, repeat	Tracking values and customer favorites helps immediately
Locations	Loch Ness, Huatulco, Outer Banks, and Point Nemo are named in the launch announcement	Route notes should include the spot, not only the fish
Collection	100+ fish species are listed for the full game	Do not trust a partial table as complete without checking the almanac
Customers	Animal, mythical, and folklore-inspired customers have favorites and tips	Favorite-fish notes are high-value
Secrets	Treasures, bottle messages, secret passages, environmental puzzles, and levers are confirmed	A spoiler-light checklist is useful before a full map
Patch	1.0.1 fixed several launch bugs	Recheck affected achievements, bait, almanac, and Point Nemo puzzle behavior
Platforms	Steam lists Windows and macOS requirements	Mac is supported; Steam Deck comfort still needs a live handheld check

First Fishing Route

Step	Do this	Why
Catch one fish cleanly	Learn timing and spot behavior	The loop starts with repeatable catches
Scale it carefully	Watch quality and time pressure	Scaling can change how useful the fish is
Serve one customer	Note favorite, reaction, and tip	Customer memory beats guessing later
Spend on one bottleneck	Upgrade the tool that slowed the run	Money should solve a repeated problem
Mark the spot	Save location and fish notes	Four locations make spot notes important
Track secrets lightly	Save puzzle, bottle, lever, or treasure leads	Cleanup gets easier after upgrades

Scale the Depths is tempting because every run feels short. That makes it easy to forget which customer liked which fish. Start tracking before the list gets large.

Best Pages By Goal

Goal	Best page	Use it for
Collection cleanup	Fish and Customer Tracker	Fish species, spots, customer favorites, sale/tip notes
Faster money	Upgrade Order	Rod, hook, bag, scaling tool, bait, and boat decisions
Lore and puzzles	Secrets and Treasures	Messages in bottles, artifacts, secret paths, puzzle gates, levers
Device setup	Steam Deck and Mac Checks	Mac requirements, Deck readability, controls, save reload

What To Save In Your Notebook

Track	Good entry
Fish	Name, spot, size/rarity cue, scaling difficulty, sale result
Customer	Name or appearance, favorite fish, reaction, tip, repeat order
Upgrade	Cost, tool type, what it improved, whether it paid off
Secret	Location, clue, blocker, return trigger, cleared state
Bug-sensitive note	Patch version or current date if a puzzle, bait, or achievement acts strangely

On day one, a personal notebook is safer than trusting a copied fish list with no build context. Save only what your game has shown, then use the tracker to turn those notes into a route for the next session.

When To Move Spots

Situation	Stay here	Move on
You just unlocked a location	Catch several common fish and serve a few customers first	Move after the same fish and reactions repeat
A customer asks for something unfamiliar	Test nearby spots and save every reaction	Move if the order clearly points to another region
Scaling keeps ruining good catches	Spend on the scaling tool or practice with lower-risk fish	Move only after the bottleneck is fixed
A bottle, lever, or gate appears	Save the clue and blocker before leaving	Return after a boat, bait, or tool upgrade changes access
Money feels slow	Filter your notes for high-tip or favorite reactions	Move if the current spot has no new customer information

The better route is not always the deepest water. If a new area gives you fish you cannot scale cleanly or customers you cannot satisfy, spend a short loop in an earlier spot, buy the upgrade that fixes the problem, then come back with cleaner notes.

Early Mistakes To Avoid

Mistake	Better habit
Selling every catch to the next customer	Match one fish to one customer and save the reaction
Buying the flashiest upgrade first	Buy the upgrade that fixes your slowest repeated step
Treating a partial fish list as final	Check your almanac and current build before planning cleanup
Ignoring low tips	Low-tip notes are still useful because they rule out a favorite
Forgetting secret blockers	Save the blocker, location, and return condition while it is fresh

Scale the Depths rewards small, repeatable loops. A good session can be as simple as three catches, three customer tests, one upgrade decision, and one secret note. That rhythm gives you enough progress without turning the fishing loop into busywork.

Patch-Sensitive Checks

The 1.0.1 hotfix notes mention several fixes that players should keep in mind while cleaning up:

Area	Recheck if…
Legendary fish/customer achievements	An achievement did not unlock before the hotfix
Baits	A bait purchase or UI behaved strangely
Point Nemo Puzzle Gate	A previously opened gate acted locked again
Almanac	A fish entry looked missing
Boss customer sequence	The same boss customer repeated unexpectedly

If one of those issues touches your save, test the current build before assuming the old behavior still applies.
