Fish It Advanced Diving Gear Location Guide

In Fish It, the Advanced Diving Gear is not a chest you swim out and grab — it is an unlock sold by the dive-gear vendor once the deep-water zone is open, and the practical “location” is that vendor’s second inventory tab. The route runs two map transitions out from the starting pier, and the gate is the deep-water progression flag rather than a key, code, or hidden spawn point. Bring a full oxygen tank, one spare refill, and a light source, because the return swim is longer than the dive itself.

Why So Many Location Guides Point Somewhere Different

Three things make this item unusually hard to pin down, and knowing them saves you a wasted session:

• “Advanced” is a tier name, not a place name. It describes the third step in the diving gear ladder, so searching for it as a map location will send you to the wrong answer.
• Vendors move between map reworks. According to the game’s official patch notes, shop placements have been adjusted more than once when zones were expanded. Any fixed coordinate you read online should be treated as a starting point, not gospel.
• Older guides predate the deep-water unlock. Before that change, the gear was available earlier in progression; those guides are now wrong about the requirement, not the location.

The reliable method is to stop hunting for a spot and start hunting for the vendor tab. The in-game map marker is the authoritative source — if your marker shows a shop icon in the deep-water hub, that is your vendor, regardless of what a forum post says.

The Route, Step by Step

1. Complete the mid-tier fishing chain to trigger the deep-water unlock. Reason: the vendor’s advanced tab is gated behind the progression flag, so walking there early simply shows an empty shelf.
2. Travel from the starting pier to the deep-water hub. Reason: this is a two-transition route, and the second transition is where most players get turned around — follow the map marker rather than the coastline.
3. Look for the dock-side shop marker, not a treasure marker. Reason: gear vendors use the shop icon; chest icons lead to consumables and bait, which is the single most common wasted trip.
4. Open the second inventory tab. Reason: the first tab stocks bait, rods, and consumables. Diving gear sits behind the tab switch, which is why some players assume the vendor does not carry it.
5. Read the stat card before you buy. Reason: the card lists depth rating, oxygen capacity, and swim speed, and those numbers — not the price — determine whether the gear actually opens the zones you are stuck on.
6. Test in shallow water first. Reason: a two-minute trial run at 20 m confirms the oxygen drain rate before you commit to a deep descent you cannot finish.

Diving Gear Tiers Compared

Which Tier Should You Actually Buy?

The Oxygen Math: How Many Deep Runs You Get

This is the calculation that decides whether the upgrade is worth it for you. Using the representative numbers from the table above:

• Advanced tank: 180 seconds of dive time.
• Descent from surface to a 60 m node at +25% swim speed: roughly 40 seconds.
• Ascent and safety stop: roughly 30 seconds.
• Bottom time remaining: 180 − 70 = 110 seconds.
• At about 25 seconds to locate and harvest one deep node: 4 nodes per tank.

With the rebreather’s 300-second capacity the same dive yields 230 seconds of bottom time, or about 9 nodes per tank — roughly 2.2× the yield for one upgrade slot. That ratio, not the depth rating, is the real argument for buying it. If you are clearing fewer than three nodes per run, the limiting factor is your route knowledge, not your gear, and a cheaper purchase is the better move.

Durability, Consumables, and Mistakes That Cost Runs

Diving gear in Fish It behaves like a consumable-heavy kit rather than a one-off purchase. What wears first, in rough order: oxygen tank charge, then the light source battery, then the fins’ speed bonus (which some builds degrade with heavy use). Seals and the mask itself rarely need attention.

Servicing is cheap but not free — expect to budget refills as an ongoing cost rather than a one-time upgrade fee, and factor that into the cost-per-run math above. Cleaning or resetting the set between sessions is not required, but recharging before you leave the hub is, because there is no refill point at depth.

The recurring mistakes, in the order players hit them:

• Buying the advanced tier before owning Standard Diving Gear, then finding the upgrade option unavailable.
• Descending without a spare refill and losing the salvage run on the ascent.
• Skipping the light source — visibility drops sharply past the mid-depth band.
• Assuming a fixed coordinate from an older guide still works after a map rework.

Frequently Asked Questions

Is the Advanced Diving Gear a hidden spawn or a shop item?

It is a shop item, not a world spawn. In the current build it is purchased from the dive-gear vendor in the deep-water hub, on the vendor’s second inventory tab. Guides that describe swimming to a fixed spot on the seabed are generally describing an older build or confusing it with a salvage chest.

What do I need before the vendor will sell it to me?

Two things: the deep-water zone unlock from the mid-tier fishing chain, and ownership of the Standard Diving Gear, since the advanced set upgrades an existing kit. A level requirement in the 25–35 band and a mid-tier currency cost are also typical. Without the unlock, the advanced tab simply appears empty.

What equipment should I bring on the first deep dive?

A full oxygen tank, one spare refill, a light source, and fins if you have them. Fins matter more than most players expect, because the descent and ascent together consume roughly 70 seconds of a 180-second tank — cutting transit time directly increases the number of nodes you can harvest.

How much bottom time does the Advanced Diving Gear actually give me?

About 110 seconds at a 60 m node once descent and ascent are subtracted from the 180-second capacity, which works out to roughly four harvests per tank. The rebreather upgrade raises capacity to about 300 seconds and pushes that to roughly nine harvests, which is the strongest argument for the upgrade.

Do I need the rebreather upgrade right away?

No. Buy the base advanced set first and spend the difference on fins and refills. The rebreather pays for itself through volume, so it is worth adding once you are consistently clearing deep nodes every session — not on the first visit to the vendor.

Where should I check if the vendor’s location has changed?

Check the in-game map marker and the game’s official patch notes first. Shop placements have been adjusted during past zone expansions, so a marker showing a shop icon in the deep-water hub is more reliable than any fixed coordinate. If the marker is missing entirely, your deep-water unlock has not triggered yet.
