Technical diving in Kubu: The Boga Wreck, the Canyon and Batu Ringgit

Tech diving on the Boga Wreck

The Boga wreck in Kubu is a great option for technical divers who want to explore a deep and intact wreck. It sits on a sloping coral reef from 18 meters down to about 38 meters, making the bottom section perfect for practicing decompression dives. On the back of the wreck at 50m, there is a big hole we call “the Fish Tank” for tech divers who want to go a bit deeper. On the Boga wreck itself, you can see a big steering wheel, the best place for a photo and even an army 4×4 in the lower deck. Because it’s deeper than other wrecks in Bali, we generally see fewer divers around. It’s an easy entry from the beach, and looking at the propeller at 38m is a great experience.

Tech diving on the Canyon

The Canyon: The Canyon is a unique site that starts at 15 meters deep and runs perpendicular to the reef, dropping into the deep for as long as the eye can see. It is a wide channel made of black volcanic sand, with coral walls on either side about 2 to 4 meters high and 10 to 15 meters wide.

Along the way, you’ll see big gorgonians, schools of fish, and a lot of healthy coral. The sea life here is very abundant. For technical divers, we usually dive to depths of 40 to 60 meters to enjoy all the canyon can offer. Once we reach our target depth, we turn left and swim toward the Boga wreck, where we begin our ascent. It is a long, interesting, and complete technical dive that lets you see two of Kubu’s best spots in a single dive.

Tech Diving at Batu Ringgit

Batu Ringgit is an excellent spot to practice tech diving. We start from the shore with a nice and easy sandy slope entry, and an easy way to get ready.

We keep the reef on our left shoulder and follow the slope until we find the stunning coral drop-off. This is a tech dive site that lets us go as deep as we want, but we generally stay between 40 and 60 meters. The site consists of large volcanic ridges with giant pinnacles, or steps.

The reef is very rich; you can see massive gorgonians and huge sponges. Visibility is generally very good, and the current is mostly slow or mild. In the deeper parts, we look for sharks, groups of tuna, schools of barracuda, and occasionally a Mola-mola being cleaned in the freshwater thermocline.

On your way back up for decompression, the shallower sandy slopes are famous for rare nudibranchs, mantis shrimp, frogfish, and anemones. The local fish and crabs give you plenty to look at during your stops.

Our Tech Protocols

Built on precision. Our protocols are designed by tech divers who respect the depth.

● Depth Limits: Max 60 meters on Trimix; max 50 meters on Air.
● Gas Planning: Our protocols limit Air to a maximum of 50m; Normoxic Trimix is mandatory for any deeper profile to ensure total mental clarity. For those prioritizing absolute situational awareness, we offer the flexibility to transition to Trimix starting from 40m.
● Configurations: Full support for Twinsets, Sidemount, and CCR.
● CCR Support: We are AP Inspiration specialists. Sofnolime (Sorb), Trimix, and Oxygen fills are available.
● Gas Blending: Precision fills of Trimix and custom Nitrox/Deco gases up to 100% O2 from a reputable, high-standard station with strict filtration.
● Safety: We are located in Sanur, with quick access to the hyperbaric chamber in Denpasar.

Requirements & Booking

● Certification: Proof of Tech certification (SSI, TDI, PADI TecRec, IANTD, GUE, etc.).
● Insurance: Must cover technical diving depths.
● Check-out: A shallow check-out/weight-check dive may be required, depending on your recent experience.
