Requirements, Age, and Comfort Factors
Scuba diving has simple requirements designed to keep you safe. Here's what you need to know.
Physical Requirements
- ✓
Basic water comfort
You don't need to be a strong swimmer, but you should be comfortable in water. If you panic easily, start with snorkeling.
- ✓
Moderate fitness
You carry tanks and weights. Reasonable cardiovascular health helps, but most people of all fitness levels dive safely.
- ✓
No medical contraindications
Operators provide a medical questionnaire. Conditions like uncontrolled asthma or heart disease may be contraindications. Your doctor can advise.
- ✓
Ability to follow instructions
Diving relies on listening and following crew guidance. This is non-negotiable for safety.
Age & Special Considerations
- 👧
Ages 8–12
Pool training available. Open water dives in shallow, calm areas with certified junior training.
- 👦
Ages 12+
Full certification courses available. Same restrictions as adults in training, then unrestricted.
- 👴
Older adults (60+)
No upper age limit. Medical clearance more important. Many people in their 70s and 80s dive safely.
- 🤰
Pregnancy
Diving is not recommended during pregnancy due to decompression sickness risk to the fetus.
Medical Disclaimer: This is general information. Always consult with a doctor and provide honest answers on the medical questionnaire. Operators prioritize your safety—don't hide medical history.

What Reputable Operators Do to Keep You Safe
Pre-dive Briefing
Every operator goes through equipment, signals, depth/time limits, emergency procedures, and site-specific hazards. No exceptions.
Diver-to-Guide Ratios
Most operators limit beginners to 4:1 (4 divers per guide). Some do 2:1 or 1:1. Smaller ratios = more attention to your comfort.
Depth & Pressure Limits
Beginners stay 20–40 feet. Certified divers can go 60 feet. These limits prevent decompression sickness and nitrogen narcosis.
Controlled Conditions
Operators cancel dives if visibility is poor, currents are strong, or weather deteriorates. Safety always comes first.
Equipment Maintenance
Rental gear is regularly serviced and inspected. Modern equipment is extremely reliable.
Buddy System
You're paired with another diver or the guide. No one ever dives alone. You look out for each other.
