Imagine renting a car in an unfamiliar city, navigating traffic on unfamiliar roads, and then finding yourself in a heavy rainstorm — only to realize you don’t know how to operate the windshield wipers. You would not want to replicate this situation underwater using rental dive gear.
Why Knowing Your Rental Gear Matters
Whatever dive equipment you use, you need to know how to operate it properly before you submerge. If you have your own gear, you’ve had the time to familiarize yourself with its operation. However, that may not be the case when you’re renting dive gear. Fortunately, there are some things you can do to ensure that you start the dive comfortable and confident with the equipment you will be using.
Check Your Dive Computer First
When renting a dive computer, make sure that you know how to read it, i.e., where to find the depth, time, no-decompression limit, remaining gas, etc. Also make sure you know the meaning of the warning beeps and/or vibrations that will occur throughout a normal dive.
If you use a gas other than air, be sure you know how to set the breathing gas mix on the computer. Some computers hold the settings from the last dive, so even if you are on air you will want to check this setting. If the computer is air-integrated, check that it is paired to the transmitter on your regulator. If it isn’t paired correctly, it might display information from someone else’s cylinder.
Fit and Function: BCDs and Regulators
The BCD should appear well cared for and fit you properly. Confirm that you can put it on and take it off without looking at the releases and be able to find the low-pressure inflator hose by feel. You should also be able to disconnect it from the power inflator without difficulty. Review whether the setup is weight-integrated or requires a weight belt, and make sure that both you and your buddy know how to release your weights in an emergency.
Regulators should be clean and well maintained. Without connecting the regulator to a cylinder, try to take a breath out of each of the second stages. Your mouth should create a vacuum, and you should not be able to get any air through it. After pressurizing the regulators, breathe through both before entering the water to make sure they work properly. If your spare second stage is integrated with your low-pressure inflator, be sure both you and your buddy are comfortable using this configuration.
Exposure Protection and Accessories
When renting exposure protection, try on a few sizes to find the suit that fits you best. It should be snug but not impede movement or breathing. Alternatively, it should not be so loose as to bunch or have rolls.
If you rent your mask, fins, snorkel, and boots, fit and cleanliness are your primary concerns. Try on everything, paying particular attention to mask fit. You don’t want a leaky mask to ruin your dive.
Confidence Using Rental Dive Gear Comes from Preparation
It’s your responsibility to start every dive feeling comfortable and confident. With rental equipment, that means allowing extra time to learn and understand the gear you will be using. If you aren’t comfortable, ask questions and or make any adjustments until you feel ready, then go treat yourself to a fantastic dive. n

Frequently Asked Questions
Why is it important to check rental dive gear before diving?
Inspecting rental gear ensures everything fits properly and functions safely. Unfamiliar or faulty equipment can cause discomfort or lead to dive incidents underwater.
What should I check when renting a dive computer?
Verify the display readings for depth, time, and remaining gas, confirm gas mix settings, and ensure it’s correctly paired if air-integrated.
How do I ensure my rented BCD fits properly?
Your BCD should feel snug but comfortable. Practice finding and using releases, the inflator hose, and weight systems before entering the water.
What should I look for in rental regulators?
Check that the regulator is clean, well-maintained, and delivers smooth airflow from both second stages after pressurization.
