Engineered & hand‑built by a cave instructor who lives the dive
I am an IANTD Advanced Technical Cave & Trimix Instructor and an active GUE Cave DPV, Cave CCR/TEC2/CCR2 diver. I have extensive experience teaching and exploring the submerged labyrinths of Mexico’s Riviera Maya. After class, when the reels are set out to dry, I retreat to my workshop to address any Personalized Diving Essentials challenges encountered underground.
Every spool, marker, and rebreather cover you see here is designed, 3‑D‑printed, and finished by me on my equipment — no outsourcing, no shortcuts, just tight tolerances and real‑world testing in the cave where it counts.
Whether you’re a seasoned diver with countless hours logged in the depths or a novice eager to embark on your underwater journey, our commitment is to enhance every aspect of your experience. Each personalized touch is a testament to your style, stories, and the expeditions waiting to unfold. With our products, you’re not just diving in waters teeming with underwater wonders; you’re diving with confidence, organization, and a flair of individuality that echoes your narrative.
Why I build
Personalized gear is essential for both practicality and individuality. That’s why each item in the collection includes an option for your chosen personalization on one side. This means you can infuse your personality into your diving equipment through various options, such as selecting your preferred colors, adding your initials, or even incorporating a unique callsign that holds personal significance.
- Identity in zero‑viz – Personalized colors and tactile cues let you read your gear and line by touch alone.
- Durability first – High‑strength polymers and dimensions proven over hundreds of cave dives, DPV runs, and baggage handlers.
- Community over volume – I’m not chasing mass production or fat margins. I’m chasing the grin you flash when a teammate says, “That’s slick—where’d you get it?”

Signature gear (Personalized Diving Essentials)
- “Hänsel & Gretel” Cave‑Line Markers. Set of 3 arrows & 8 cookies. Choose the base color plus “z‑teeth” pattern you specify (1–3 teeth), which is easy to identify by touch during a silt‑out. Your callsign is molded on one face, so it is easy to find your way out.
- The “Ariane” Finger Spool. The mid-width hub is sized for both bare hands and thick gloves, and the flared rims are for easy winding. It is supplied with your choice of line: #24 nylon (30 meters, white) or #18 nylon (45 meters, range of colors). Your personal colors and nickname wrap one flange, so you and your teammates are never puzzled by many spools on the jumps.
- JJ‑CCR Loop & T‑Piece Covers. Two pairs of screw‑in caps — two for each head loop end, and two covers for T-pieces. Plus, two plugs for the oxygen head inlet and oxygen hose. Same styling as the headcover, with your ID on one side.
- JJ‑CCR Headcover. Thread‑on cap for the JJ head with drainage ports; ribs add strength while keeping weight low. Initials or callsign recessed into the middle.
