Spearfishing with a GoPro: Camera Settings, Mounts, and How to Get Great Footage

I didn't start filming my dives because I wanted to become an underwater content creator. I started because I kept coming home from sessions and struggling to describe what happened down there -- the way a white sea bass materialized out of the green, or the exact moment a yellowtail committed to the flasher. I wanted to capture those moments, study them, and share them with the people who understand why they matter.

If you've been thinking about strapping a GoPro to your setup, this guide covers everything I've learned through trial, error, and a lot of unusable footage -- from camera settings and mount choices to editing tips and the mistakes that took me way too long to figure out.

Why Film Your Dives?

Filming your dives serves a lot more purposes than racking up views online. Here's why I think every serious diver should consider it:

It's the best learning tool you'll ever have. Watching your footage back reveals things you'd never notice in the moment -- your approach angle was wrong, you kicked too aggressively on the descent, or you held your breath longer than you thought. I've improved more from reviewing my own footage than from any other single thing.

It helps you share the experience with people who weren't there. Non-diving friends and family finally get to see what you actually do underwater, and your dive buddies get to relive the session from a perspective they didn't have.

It creates a personal archive of your diving life. Years from now, you'll be glad you recorded that first yellowtail or your buddy's personal best halibut. These memories fade fast without footage.

It supports conservation. Documenting conditions, species, and behavior underwater contributes to the broader understanding of our ocean. Divers are uniquely positioned to show what's happening below the surface, and that footage can matter for advocacy and marine protection efforts.

Which GoPro Model for Spearfishing?

GoPro has dominated the action camera market for spearfishing, and for good reason. They're compact, waterproof out of the box (to at least 33 feet on most modern models, deeper with a housing), and the image stabilization has gotten genuinely impressive.

The Hero 12, Hero 13, and the newer models all produce excellent underwater footage. Here's what actually matters when choosing:

Depth rating is the first consideration. Most GoPro bodies are rated to 10 meters (33 feet) without an additional housing. If you're diving deeper than that -- and most of us are -- you need a waterproof housing rated to at least 60 meters. The official GoPro protective housing and various third-party options will get you there. Don't skip this. Flooding a camera at 60 feet is an expensive lesson.

Image stabilization matters more than resolution for most diving footage. HyperSmooth on newer GoPro models does an incredible job of eliminating the jittery, nauseating shake that ruins so much underwater video. If you're choosing between an older model with higher resolution and a newer model with better stabilization, go with stabilization every time.

Battery life is a real factor. Underwater use drains batteries faster, especially in cold water. Newer models have improved, but you're still looking at roughly 45-75 minutes of continuous recording depending on settings. I'll cover strategies for managing this later.

If you're buying your first camera specifically for diving, the latest Hero model you can afford is generally the right call. Each generation has brought meaningful improvements in stabilization, low-light performance, and color accuracy -- all things that matter significantly underwater.

Camera Settings That Actually Work Underwater

This is where most people's footage goes from "that could have been great" to "I can't watch this." The default GoPro settings are designed for land use, and underwater is a completely different environment. Here's what I've dialed in over hundreds of dives:

Resolution: 4K vs. 1080p

4K looks incredible on a big screen and gives you room to crop in post-production without losing quality. But it eats battery life and storage space fast, and some older phones and computers struggle to edit it smoothly. For most divers, 2.7K is actually the sweet spot -- it still looks sharp, gives you cropping room, and is much easier on your battery and editing workflow. If you know you'll only be sharing on Instagram or YouTube and don't plan to crop, 1080p is perfectly fine and will nearly double your recording time compared to 4K.

Frame Rate: 60fps for Action, 24fps for Cinematic

Frame rate is one of the most impactful settings for spearfishing footage. I shoot at 60fps almost exclusively because it gives me the option to slow footage down to half speed in post-production, which is perfect for showing the shot, the fight, or a close encounter with marine life. That slow-motion replay of a fish turning on a flasher or a clean stone shot is what makes spearfishing footage compelling.

24fps gives footage a more cinematic, filmic look but you lose the ability to create smooth slow motion. If you're primarily making edited dive films with music and want that documentary feel, 24fps has its place. But for capturing the action of spearfishing, 60fps is the way to go. Some divers shoot at 120fps for ultra-slow-motion, but the trade-off in resolution and the massive file sizes rarely justify it for typical use.

Field of View: Wide vs. Linear

Wide angle is generally the right choice underwater. Water already narrows your effective field of view compared to air, and the wide setting compensates for that. It also makes it much more forgiving if your camera isn't pointed perfectly -- you'll still capture the action even if it's slightly off-center.

Linear mode removes the fisheye distortion that wide angle creates. It looks more natural, but you lose a lot of the frame -- and underwater, where things happen fast and from unexpected angles, that narrower view means you'll miss more shots. I use wide for most diving and only switch to linear for topside footage or very deliberate, composed shots.

Color Profiles

If you plan to color correct your footage in post (and you should -- more on that below), shoot in a flat color profile. On GoPro, this means using the "Natural" or "Flat" color setting rather than "Vibrant" or the default GoPro color. Flat profiles retain more color information in the highlights and shadows, giving you much more flexibility when correcting underwater color shift. If you don't plan to edit at all, the default GoPro color can look decent, but you're leaving a lot of quality on the table.

White Balance and Color Correction Underwater

Here's the fundamental challenge of underwater video: water absorbs red light first. By 15 feet deep, most of your red tones are gone. By 30 feet, oranges are disappearing too. Everything shifts blue or green depending on the water. This is why raw underwater footage often looks like it was shot through a blue-green filter.

There are two approaches to dealing with this: red filters and post-production color correction.

Red filters snap onto your GoPro housing and physically add red back into the image. They work reasonably well in blue tropical water between about 15 and 70 feet. In green water -- which is what most of us on the California coast are dealing with -- a magenta filter is more appropriate. The downside of filters is that they're depth-specific. A filter tuned for 30 feet will overcorrect at 10 feet and undercorrect at 60. They also reduce overall light entering the lens, which can be a problem in already-dark conditions.

Post-production color correction is the more flexible and ultimately superior approach, but it requires shooting in a flat color profile and spending time in editing software. Tools like DaVinci Resolve (free), Adobe Premiere, or even GoPro's own editing app can restore natural colors by boosting reds and reducing blues/greens. The results are dramatically better than filter-only footage, and you have precise control for different depths within the same dive.

My recommendation: skip the filter, shoot flat, and color correct in post. It takes more time but the quality difference is substantial.

Mount Options: Where to Put Your Camera

Mount choice is arguably the single biggest factor in footage quality after camera settings. Where you put the camera determines what you capture, how stable it is, and whether it interferes with your diving. I've tried every major option, and they each have distinct strengths and weaknesses.

Head Mount

The head mount (usually a strap system or a mount attached to your hood or beanie) captures a true point-of-view perspective. The camera sees roughly what you see, which makes for immersive footage where viewers feel like they're on the dive with you. It's hands-free, so it doesn't affect your diving at all. The downside is that every head turn creates motion, and even normal scanning can make footage jumpy. It also won't capture your face or body, so the viewer only sees what's in front of you. Head mounts are excellent for documenting reef exploration, approaches, and the hunting process.

Gun Mount

Mounting the camera directly to your speargun barrel captures exactly where the gun is pointed, giving you a front-row seat to the approach, the shot, and the fish's reaction. This is the most popular mount for spearfishing-specific content and produces the most dramatic shot footage. The camera is naturally aimed at the target, so your framing is often excellent without any thought. The downsides: you only capture what the gun is aimed at, so you miss everything happening behind or beside you. The gun's recoil can also jolt the camera at the moment of the shot, and if your gun is resting at your side, the camera is filming the seafloor or your fin.

Mask Mount

A mask-mounted camera clips or straps to the side of your mask frame. It offers a POV very similar to a head mount but sits lower, closer to your actual eye level. Some divers find it more natural-looking than a head mount. However, it can create drag on one side of the mask, cause minor discomfort on longer dives, and the offset angle means the camera doesn't quite see what you're looking at -- it's always slightly to the side. The added weight can also affect your mask seal if it's not secured well.

Chest Mount

The chest mount harness positions the camera on your sternum, pointing forward. It captures your arms, gun, and everything in front of you while also showing the environment. This gives a unique perspective that includes the diver's body in the frame, which looks great in edited content. The downside for freediving is that chest mounts can interfere with your weighting and wetsuit comfort, and the angle shifts as your body position changes during descent and ascent. It works best for scuba-based filming and is less ideal for active freediving.

Pole/Selfie Mount

A handheld pole or extendable stick lets you point the camera wherever you want, creating the most versatile framing options. You can film yourself, your buddy, marine life, or alternate between all three. For capturing the moment a fish is landed or showing a diver ascending with their catch, nothing beats a handheld stick held by a buddy or by yourself during surface intervals. The obvious problem: it occupies a hand. You can't hold a pole and a speargun effectively at the same time. This is best used by a dedicated camera person on the boat or during surface activities, not during active hunting.

My setup for most dive days: gun mount as the primary angle with a head mount when I want broader environmental footage. If a buddy is willing to film, a handheld pole produces the best overall content by far.

Lighting Considerations: Shallow vs. Deep, Clear vs. Murky

Light is everything in underwater video, and you have far less control over it than you do on land. Understanding how light behaves underwater will dramatically improve your footage without changing a single camera setting.

In the first 15 feet, you have plenty of ambient light and colors are relatively intact. This is where footage looks best with the least effort. Shallow reef dives, surface-level fish encounters, and topwater action all benefit from that natural light. The best footage of the day is almost always shot within 20 feet of the surface.

Below 30 feet, light drops off significantly and color shift becomes pronounced. Your footage will look increasingly blue or green, and details in shadows start to disappear. This is where a flat color profile and post-production correction become essential rather than optional.

Murky water (common in California, especially after storms or in river-influenced areas) scatters light and reduces contrast. In low-visibility conditions, footage tends to look flat and hazy regardless of your settings. Getting closer to your subject is the single best thing you can do -- within 3 to 4 feet, even murky water produces decent footage because there's less water between the lens and the subject. Shooting with the sun behind you also helps, as it front-lights whatever you're filming.

Midday sun (10am to 2pm) punches the most light into the water column and produces the best natural colors. Early morning and late afternoon can produce beautiful surface-level footage with sun rays, but at depth you'll be fighting darkness. Plan your filming around the sun angle when possible.

Battery Life Management

Battery life is one of the most frustrating parts of filming dives. Cold water (below 60 degrees Fahrenheit) accelerates battery drain, and higher-resolution recording settings eat power faster. A fully charged GoPro battery shooting 4K at 60fps in cold water might give you 35-45 minutes. That's not a lot when a dive day can run 4-6 hours.

Carry at least two spare batteries, ideally three. Keep them in a dry bag on the boat, clearly labeled as charged versus used. Swap between dives -- don't wait until the camera dies mid-session.

Turn off Wi-Fi and GPS on the camera. These features drain power in the background and serve no purpose while you're underwater. Turn off the front and rear screens as well, or set them to auto-sleep after a few seconds. Every bit of power savings extends your recording time.

If you don't need to record continuously, use the quick capture feature that starts recording when you press the shutter button and stops when you press it again. This saves battery by only recording when you're actually diving, rather than filming your surface interval conversations and the seafloor while you're floating between dives.

Memory Cards: Don't Cheap Out

A slow memory card will cause your GoPro to drop frames, stutter, or stop recording entirely -- especially at higher resolutions and frame rates. You need a card rated V30 (Video Speed Class 30) at minimum for 4K recording. For the latest GoPro models, a UHS Speed Class 3 (U3) card with at least 128GB capacity is the baseline recommendation.

A 128GB card holds roughly 2.5 hours of 4K/60fps footage or about 5 hours of 1080p/60fps. For a full day of diving, 256GB gives you breathing room. Bring a backup card in your dry bag. Cards fail, get corrupted, or fill up at the worst possible moment.

One more thing: format your memory card in the camera before each trip, not on your computer. Formatting in-camera ensures the file structure is optimized for the GoPro and reduces the chance of recording errors.

Basic Editing Tips for Dive Footage

You don't need to be a professional video editor to make your dive footage look great. A few basic techniques make a massive difference.

Color correction is the single most impactful edit. Boost your reds, reduce blues, increase contrast slightly, and push saturation up a touch. Even a basic auto-color-correct in most editing apps will dramatically improve the look. DaVinci Resolve is free, powerful, and has excellent color correction tools. If you want to keep it simple, the GoPro Quik app on your phone can do basic corrections automatically.

Trim ruthlessly. Nobody wants to watch three minutes of you swimming over empty sand to reach the reef. Cut to the good parts. A 4-hour day of recording should produce a 3-5 minute highlight video at most. Find the best 10-15 clips, trim each one tight, and stitch them together.

Use slow motion selectively. Slowing down the shot, the fish on the stringer, or a dramatic dive down to a reef looks incredible. Slowing down your buddy swimming back to the boat does not. Save the slow motion for 2 or 3 key moments per video for maximum impact.

Add music that matches the pace of the video. Mellow tracks for scenic reef footage, something with energy for the hunt sequences. Keep in mind that YouTube and Instagram will flag copyrighted music, so use royalty-free tracks from their respective audio libraries or from sites that specialize in royalty-free music.

Common Mistakes (and How to Avoid Them)

I've made every one of these. Learn from my mistakes so you don't have to make them yourself.

Forgetting to hit record. This is the most common and most painful. You surface after the best dive of the day, grab the camera, and realize the red light isn't on. Build a ritual: every time you put the camera in the water, check the recording indicator. Some divers keep a red filter or colored tape near the record button as a visual reminder. Quick Capture mode helps too, since it starts recording with a single press.

Bad mounting angle. Your camera was slightly tilted or pointed 10 degrees too low, and now your entire dive footage is off-axis or showing nothing but reef rock. Always check your camera angle on land before the first dive. Record a few seconds on the surface, review it, and adjust. It takes 30 seconds and saves hours of wasted footage.

Fogged lens. Temperature differences between the air and water (or between a warm camera housing and cold water) cause condensation on the lens or inside the housing. Anti-fog inserts are cheap, lightweight, and essential. Place one inside the housing every time. Breathing on the lens and wiping it is a myth -- that actually makes it worse.

Shaky footage. Even with HyperSmooth, excessive body movement creates unwatchable video. The key is to move the camera slowly and deliberately. When you spot a fish, resist the urge to whip the camera toward it. Smooth, steady tracking shots are always more watchable than quick jerky pans. Practice keeping your head and body still when something interesting is happening.

Filming too far from the subject. Underwater, visibility and clarity drop off fast with distance. That fish that looked huge and close in person will appear as a tiny blur on camera 15 feet away. Get as close as safely possible. The best underwater footage is almost always shot within 6 feet of the subject.

Camera Etiquette: When NOT to Film

Cameras have become so ubiquitous that we need to talk about when it's appropriate to leave them off.

Always ask before filming other divers. Not everyone wants their techniques, their spots, or their faces on the internet. A quick "Hey, mind if I film today?" goes a long way. Respect a "no" without making it weird.

Never film at someone else's spot without permission, and be extremely cautious about showing identifiable landmarks, GPS coordinates, or location details in your footage. Burning someone's spot by posting recognizable footage online is one of the fastest ways to lose dive buddies and gain a bad reputation in the community.

If the camera is interfering with your diving, turn it off. A camera that's distracting you from safety, situational awareness, or your breathhold discipline is a net negative regardless of the footage it might capture. Your job underwater is to dive safely first. Content creation is always secondary.

If you're diving with someone new or at a new location, leave the camera in the boat for the first dive. Get a feel for the conditions, the people, and the environment. There will be plenty of time to film once you've established trust and comfort.

Final Thoughts

Filming your dives adds a dimension to the sport that's hard to appreciate until you see your first well-shot highlight reel from a personal session. The technology has gotten good enough and affordable enough that there's really no reason not to bring a camera along. Start simple -- a GoPro on your gun, shooting 1080p at 60fps in wide angle with a flat color profile -- and build from there as you learn what works for your style of diving.

Your first few sessions with a camera will produce mostly unusable footage, and that's normal. Every diver who films has a hard drive full of blurry, blue, badly angled clips from the learning phase. Keep at it. Dial in your settings, experiment with mounts, and review your footage after every session. Within a handful of dive days, you'll be producing clips you're genuinely proud of.
