Spring marks the start of a new dive season for many of us, and while excitement levels are usually high, skills can get a little rusty after time out of the water. Even experienced divers benefit from a refresher, especially when conditions, equipment, or personal fitness have changed over the off-season. Revisiting core scuba skills helps rebuild confidence, improve comfort underwater, and reduce stress for both you and your dive buddy.
In this guide, we walk through five essential scuba skills worth refreshing at the start of the season, along with practical ways to practice them and common issues that can creep in after time away from diving.
1. Buoyancy Control
Buoyancy control affects almost every aspect of a dive, from air consumption to environmental protection. After time away from diving, it is common to feel slightly unstable in the water, especially if your weighting, exposure suit, or equipment setup has changed. Poor buoyancy can lead to accidental contact with the reef, rapid ascents, or unnecessary fatigue.
A great way to refresh buoyancy is to start shallow, ideally around 5 meters (16 feet), and focus on slow, controlled breathing while hovering. Practice fin pivots and static hovers, adjusting your buoyancy using your breath before reaching for your buoyancy control device. Swimming slowly through different depths while maintaining neutral buoyancy also helps rebuild muscle memory.
One of the biggest contributors to unstable buoyancy is over-weighting. Carrying too much lead forces you to add extra air to your buoyancy device, which can create a constant up-and-down motion. A quick weight check at the start of the dive season often solves this.
Another helpful test is whether you can hover motionless for 20 to 30 seconds without touching your inflator. If that feels difficult, focus on slower breathing and let your lungs do more of the fine-tuning.
If you want to take your skills further, a structured program like SSI’s Perfect Buoyancy specialty can help refine your control and efficiency in the water.
2. Mask Skills
Mask issues are one of the most common sources of stress for divers, particularly early in the season. A leaky or flooded mask can distract you from your surroundings and quickly raise anxiety if the skill feels unfamiliar. Refreshing mask skills helps ensure that small problems stay small.
Start by practicing partial and full mask clears in shallow water where you can stand if necessary. Concentrate on slow exhalation through your nose while gently pressing the top of the mask frame. Once this feels comfortable, practice removing and replacing your mask while neutrally buoyant so the skill becomes automatic again.
Many divers make mask clearing harder than it needs to be by lifting the mask too far from their face, allowing more water to enter. Instead, break the seal only slightly at the bottom of the skirt.
Another common problem is using a short, forceful burst of air that fails to clear the mask fully. A slow, steady exhale tends to be more effective. If water continues leaking into your mask, it may be worth checking the fit. Hair, hood material, or a poorly sized mask can prevent a proper seal.
3. Dive Kit Checks
A thorough dive kit check is one of the simplest ways to improve safety, yet it is often rushed at the start of the season. Equipment that has been stored for months may develop small issues such as stiff hoses, low batteries, or worn O-rings that are easy to miss without a careful inspection.
Before your first dive, assemble your equipment slowly and methodically. Confirm that your regulator breathes smoothly from both second stages, your buoyancy control device inflates and deflates properly, and your weights are secure and easily releasable. It is also wise to check exposure suit zippers, mask straps, and fin straps for signs of wear.
Many divers assume their gear is ready simply because it worked last season, but storage time is when small problems often develop. Treat the first dive of the year like a mini equipment test: assemble the full kit, inflate and deflate the BCD, breathe from the regulators, and check all electronics before entering the water.

4. SMB Use
Surface marker buoys are an essential safety tool, especially in areas with boat traffic, currents, or drift diving. Many divers carry one regularly but rarely practice deploying it, which can make the skill feel awkward when it is suddenly required.
A good way to refresh this skill is to practice deploying your SMB from a shallow depth of about 6 to 10 meters (20 to 33 feet) while maintaining neutral buoyancy. Keep the line organized, add just enough gas to inflate the buoy, and monitor your depth throughout the process.
One issue divers often encounter is overfilling the buoy in a single burst, which can create an unexpected upward pull. Using small, controlled bursts of gas allows the SMB to inflate gradually and keeps the process manageable.
Another challenge occurs when divers focus so much on the buoy that they forget about buoyancy and depth control. Establish a stable hover first, then begin the deployment. Practicing this sequence in calm conditions makes the skill much easier to manage when conditions are less ideal.
5. Buddy Communication
Clear communication with your dive buddy is vital, yet it is often overlooked during refresher dives. After time away from diving, hand signals may feel less automatic, and unfamiliar dive partners may interpret signals differently.
Before entering the water, take a few moments to review standard signals and confirm communication for air supply, direction changes, and any special considerations for the dive. Underwater, maintain regular eye contact and use deliberate, easy-to-read signals rather than rushed gestures.
Communication problems often happen when divers assume their buddy understood a signal without waiting for confirmation. Pausing briefly to look for a clear response prevents confusion later in the dive. Physical spacing also matters—if divers drift too far apart, even clear signals become difficult to see. Maintaining a comfortable side-by-side distance improves communication and awareness of each other’s air supply, buoyancy, and overall comfort.
Refreshing core scuba skills at the start of the season sets the tone for safer, more enjoyable diving throughout the year. A scuba refresher course with a diving instructor can also be a helpful way to rebuild comfort in the water. With a little practice, your foundational skills will quickly return, allowing you to focus on what really matters: relaxed dives and unforgettable underwater moments.
