If you’ve been exploring the Crystal Depths update in Fish It, you’ve probably hit that frustrating oxygen wall like I did. The standard diving tank just doesn’t cut it anymore when you’re trying to reach the Leviathan or those deep-sea relics that everyone’s talking about.
Trust me, I spent way too many hours drowning with basic gear before I figured out the Advanced Diving Gear system. Let me save you that headache and break down exactly where to find, buy, and master this game-changing equipment.
The Advanced Diving Gear isn’t just another cosmetic item—it’s your ticket to the endgame content in Fish It’s Crystal Depths update. This red-colored diving equipment completely replaces your standard yellow tank and unlocks areas that were previously inaccessible.
What makes this gear special? It’s the only way to survive the crushing pressure of the deep sea zones and access the Crystal Depths, where the rarest fish like the Blue Sea Dragon and Cursed Kraken await. Without it, you’ll hit invisible barriers or drown before reaching anything meaningful.
As someone who’s been playing Fish It since launch, I’ve got to say the Crystal Depths update (released January 18, 2026) is exactly what the game needed. It’s not just another fishing spot—it’s a whole new progression system that actually rewards skill and dedication.
The best part? The Advanced Diving Gear opens up a completely different gameplay loop. Instead of just casting lines and waiting, you’re now exploring underwater caves, completing NPC quests from characters like Hank and Dorian, and farming Crystals for those coveted Crystalized Mutations. It transforms Fish It from a simple fishing game into an underwater adventure.
First things first, you need to make your way to Pirate Cove island. This isn’t your starting area, so spawn your best boat and set sail. The island is easy to spot with its pirate-themed structures and the large lake in the center.
Once you land at Pirate Cove, head inland toward the center of the island. You’re looking for the large lake—this is where the magic happens. The Diving Merchant NPC stands near the water’s edge or on a dock in the middle of the lake.
Pro tip: The Advanced Diving Gear is located above a small wooden crate near the lake, so keep your eyes peeled for that distinctive red equipment.
Here’s the reality check—the Advanced Diving Gear costs 1,000,000 Coins. Yeah, that’s a million coins. This makes it one of the most expensive utility items in the game, and it’s definitely endgame content.
Money-Making Strategy: Before making the trip, I recommend farming high-value fish in the shallow coral areas or grinding daily quests. The Pirate Event Pass also offers decent rewards if you’re consistent with daily quests.
Once you have the coins, interact with the Diving Merchant and buy the Advanced Diving Gear. But don’t forget—you actually need to equip it! Here’s how:
With your red tank equipped, head to the static boat in the middle of the lake near the Carpenter NPC. When you get close to the long pole next to the boat, you’ll see a “Descend” option appear.
Press E on PC to interact with the pole. Your character will slide down and dive deep into the water without taking any damage. After a few seconds, you’ll emerge in the Crystal Depths.
The Crystal Depths isn’t just a pretty underwater area—it’s packed with content:
Once you’re in the Crystal Depths, I recommend using either the Element Rod or Diamond Rod for the best catch rates. The rare fish here require serious equipment—don’t even try with basic rods.
Keep an eye out for Leviathan admin boost events. During these events, global luck jumps to 200,000 for 10 minutes, making it the perfect time to target those ultra-rare fish. Mutation rates also increase during this window.
Complete Hank’s quest to get the Pickaxe, then farm Crystals throughout the Crystal Depths. These boost your odds of getting the Crystalized Mutation, which significantly increases fish values.
Want to take it to the next level? The Leviathan Den is the ultimate endgame content, but it requires some serious work:
The quest requires:
Make sure your oxygen tank is RED, not yellow. If it’s yellow, you’re still using basic gear. Double-check that you’ve equipped the Advanced Diving Gear from your inventory.
Focus on:
The merchant is near the center lake at Pirate Cove, often on a dock or near the water’s edge. Look for the red diving gear above a wooden crate—that’s your landmark.
The Crystal Depths event is time-limited and ends on January 25, 2026, so don’t wait too long to get your Advanced Diving Gear. The current update includes:
No, the game prevents you from diving deep enough. You’ll hit invisible barriers or drown with standard gear.
Absolutely. It unlocks endgame content, rare fish worth millions, and progression that’s impossible otherwise.
Yes! Some players gift the gear to friends, which is a nice alternative if you’re short on coins.
No, once purchased and equipped, it’s permanently yours to use.
Basic gear is yellow and limits you to shallow waters. Advanced gear is red and allows unlimited depth access in Crystal Depths.
Getting the Advanced Diving Gear in Fish It is definitely a grind, but it’s absolutely worth it. The Crystal Depths content represents some of the best gameplay Fish It has to offer, with rare fish, engaging quests, and that sense of exploration that makes gaming so rewarding.
Remember, the event ends January 25, 2026, so don’t procrastinate. Start saving those coins, complete your daily quests, and get ready to explore the depths like never before.
