When you are working as a professional diver, your gear is not just equipment—it is your livelihood. Scuba diving instructors need gear that can survive daily dives, travel, and the wear of teaching while still delivering safety and reliability. The challenge? Knowing which products are worth investing in.
In this essential guide, we break down the best diving gear for scuba diving instructors—from rugged BCDs and regulators to pro-level dive computers and exposure suits—so you can focus on teaching, not troubleshooting.
Quick Picks for Pros
Want the short version? Here are the top gear picks every scuba diving instructor should consider—tested, durable, and built for professional use.
Essential Gear for Scuba Diving Instructors
Choosing the right equipment is one of the most important steps for scuba diving instructors. Your gear not only keeps you safe but also sets the standard for your students. The following recommendations highlight durable, professional-grade options designed to withstand the demands of teaching.
1. BCDs Built for Durability
Scuba diving instructors spend countless hours inside their trusty BCD, taking it to multiple locations, from warm tropical waters to trickier dive spots with colder temperatures or overhead locations. So comfort, durability, and functionality are vital.
The Mares Dragon BCD offers over‑engineered lift capacity and heavy‑duty components designed to resist frequent packing, strap abrasion, and exposure to sun and salt. It includes adjustable weight pockets and tank mounts that maintain position even with students climbing in and out of the water behind you.
Alternatively, the Mares Prestige BCD delivers a streamlined yet reinforced jacket-style build with adjustable inflation and commendable buoyancy distribution. The low‑profile harness system adapts easily to different exposure suits, and friendly serviceability means scuba diving instructors can replace worn parts without discarding the entire unit, helping save cost and reduce waste.
2. Reliable Regulators for Instructors
As scuba diving instructors, your regulator is arguably the most important piece of equipment in your gear bag. It will join you on long days in the water, performing demonstrations, deep dives, student rescue practices, and much more. Your regulator is your lifeline and not a place where you want to skimp.
The Mares Prestige 15X has proven itself through balanced diaphragm design, durable construction, and smooth breathing response across varying depths. Its soft‑purge second stage makes teaching safety drills seamless, while supporting quick recovery from free-flow situations.
For technical diving or nitrox/enriched gas courses, the Mares 28XR‑HR could be more suited. Its modular build and multiple high-pressure ports make it ideal for twin sets, sidemount, or stage bottle configurations. The rotating turret on the first stage simplifies hose routing and helps instructors demonstrate gear setups effectively to students. Robust materials and environmental sealing ensure consistent performance in both tropical and cooler waters.

3. Dive Computers for Multi-Gas Use
Scuba diving instructors who lead deep or nitrox dives need a dependable computer capable of handling various gas mixes.
The Mares Quad Ci computer offers multi-gas planning, a bright and intuitive display, Bluetooth syncing for quick log uploads, and a rugged case designed for boat handling and regular impacts. Its sophisticated RGBM algorithm adapts well to professional use and repetitive dives.
Another excellent model is the Mares Sirius, which features a user‑friendly interface, easy switching between gas mixes, and battery life built to last extended instructional sessions. Both computers support nitrox and offer customizable conservatism levels, ideal for guiding students safely.

Backup masks and fins keep lessons running smoothly when equipment fails.
4. Backup Masks and Fins That Last
Scuba diving instructors know that gear failures happen. Mask straps can break, and fin straps can snap, so having backups can make all the difference between continuing a lesson or cutting the dive day short.
The Mares X‑Vision Ultra LiquidSkin mask features flexible silicone, a wide field of view, a fog-resistant fit, and durability that resists cracking or warping. It is comfortable enough to swap in if a student's mask leaks unexpectedly.
The Mares Avanti Quattro+ fins are a stalwart favorite. They offer a channel-blade design with excellent propulsion and shock resistance—helpful during long surface swims or instructor-led recovery drills.

Exposure suits protect instructors in both tropical and cold-water conditions.
5. Exposure Suits for Every Environment
The range of teaching locations is wide, from calm tropical reefs to colder choppy seas, so exposure protection might be something you need to consider. Getting cold while teaching is no fun!
The Mares Evolution 7, 7mm Wetsuit features reinforced seams, knee pads, and high-stretch neoprene that stands up to frequent saltwater soaking and constant wear. It keeps scuba diving instructors comfortable while managing intense dive schedules or long surface intervals in temperate air conditions.
For colder or varying conditions, the Mares XR3 Drysuit offers thermal protection, ease of donning and doffing, and reliability across seasons. With double-dome zippers, reinforced soles, and carefully designed seals, the suit reduces heat loss while you conduct multi-dive training days or rescue practice. Quality exposure suits can extend bottom times, reduce fatigue from a long day in the water, and enhance safety.
6. Gear Bags Made for Travel
Traveling between dive centers, remote islands, or classroom-to-site transitions requires trusty gear bags that protect all your valuable equipment.
The Mares Cruise Roller Bag is built with rugged wheels, weather-resistant fabric, and reinforced zippers that survive constant handling. Separate compartments help scuba diving instructors organize masks, fins, regulators, dive computers, and notes, reducing setup time before classes.

7. Instructor Slates and Communication Tools
Underwater communication is so important for teaching, and hand signals can only get you so far when trying to explain something to a student. Underwater slates are very helpful and inexpensive, but they need to resist the repeated dunks of a dive day.
The Mares Underwater Slate is rugged, double-sided with predrilled holes, and comes complete with attached pencil and lanyard. It withstands rough handling and remains legible even in cold water.
8. Tool Kits for Professional Needs
For those teaching in more remote or high-volume locations, the Mares Technical Tool Kit offers comprehensive tools: hex keys, hose clips, extra screws, and fin adjustment tools. This kit ensures scuba diving instructors can handle unexpected gear needs or student fittings on the spot.

Why Quality Gear Matters
As scuba diving instructors work through hundreds of dives each year, their gear must consistently perform without failure. Investing in high-quality equipment such as BCDs, regulators, computers, and backups reduces the risk of failures or breakages during training sessions—minimizing student disruptions and reinforcing safety standards.
When students see an instructor using well-kept, reliable gear, it builds trust and communicates professionalism.
Whether you are leading an SSI Open Water Diver course, teaching buoyancy control, or working on safety stops, dependable gear matters. It allows you to focus on what matters most: helping your students thrive.
Choosing the Right Gear as a Scuba Diving Instructor
Scuba diving instructors need gear that is as resilient and dependable as their commitment to teaching. Whether you are an experienced instructor with years of experience or you are about to embark on your SSI Open Water Instructor course, get the right kit. You are investing in a career built around safety, continuity, and conscientious diving.
