What is the Best Depth for Spearfishing?

Spearfishers enjoy pushing their bodies and minds to the limit while diving to the ocean's depths. A greater variety of larger fish can be found on a deeper dive. No specific depth limit applies to spearfishing. Due to the lack of guidelines on how deep you should go, it's largely a matter of personal choice and ability.

5-Meter-Depth Spearfishing

For most newcomers, spearfishing at a depth of 5 meters appears to be far too simple and uninteresting to warrant their time and attention. Observing seasoned spearos who are taking risks and diving to depths of up to 25 meters makes them feel left out. As if the good fish are found near the ocean's bottom. Which is obviously incorrect. In reality, it's the inverse of what you'd expect. Truth be told, knowing your bounds and being aware of the pressure you'll experience every additional meter you swim underwater. First-timers need to know what's going on inside and how much pressure they're under. At a depth of 5 meters, the pressure equals that of the normal atmosphere. As a result, your lungs, cardiovascular system, and blood pressure will not be put under any additional stress. It's true that at this depth, you may encounter large schools, but the upside is that visibility is better, and you can stay underwater for longer periods without risking unpleasant experiences when exiting.

10-Meter-Depth Spearfishing

When you go from one depth to another underwater, the pressure increases respectively. Pressure has an impact on your skin as well as your choice of suit, but it can also have devastating effects on your inner organs. The temperature of the water begins to change at a depth of 10 meters. Even in hotter regions, the temperature of the water drops as you go deeper. Think twice before going spearfishing at 10 meters deep while wearing only your swimsuit. The increasing pressure in the water will most likely be detected by your lungs first. Lungs must expand under normal atmospheric pressure to take in and then expel the air after oxygen extraction. With double the atmospheric pressure, one's lungs have difficulty expanding because the added pressure is trying to squish them. An increase in blood flow will equalize the pressure in your lungs to prevent them from collapsing, thereby keeping them functional. Some interesting fish species can be found at this depth. Schooling groupers and hogfish can be found here.

15-Meter-Depth Spearfishing

The time has come for us to take spearfishing seriously. You're swimming in 2.5 times the normal atmosphere at 15 meters. Having logged hundreds of hours of diving by this point, you're confident in your abilities both under pressure and in handling yourself while underwater. While diving to 10 meters may have felt dangerous, it's nothing compared to being 15 meters underneath the ocean's surface. As you may be aware, our skulls are filled with cavities. The sinuses, larynx, middle ear, and pharynx are all included in this group. Like that of air-filled cavities, the pressure within these cavities becomes more unstable as more pressure is applied. Consider the airspace in the middle of the ear. In any position, it aids in maintaining your equilibrium. Increased middle ear pressure can cause both balance problems and excruciating pain if it isn't equalized. The amount of pollution in the water affects visibility. Most water bodies darken at this point. It's important to remember that you can only dive to this depth in saltwater.

20-Meter-Depth Spearfishing

The major leagues aren't too far away now. If you're capable of diving to a depth of 20 meters to look for elusive fish, you're close to being in peak athletic condition. Of course, your body shape, age, and overall health all play a role in how well you can swim at this level. To put it another way, you must be in excellent physical condition, free of any health issues like heart conditions or blood pressure. It's only logical that you'd seek medical clearance before making such a risky dive. In addition to your cranial space and lungs, your heart feels the strain of working under such pressure. The increasing water pressure forces your body to work overtime even if you're just standing in the water. It's obvious, though, that you aren't. Your heart is racing as you race to catch a glimpse of that elusive yellowtail you just saw. This, of course, raises the stakes and puts people at greater risk.

25-Meter-Depth Spearfishing

So, you've made it to the end, right? You've pushed your body to its limits, overcome your fears, and improved both your physical and mental state. This is the deepest you can dive underwater without harming your ability to catch fish. Of course, this level of commitment is not for everyone. Once more, this isn't a contest, and you have nothing to prove to anyone. Under such extreme circumstances, your body must be in the excellent physical condition and possess tremendous stamina. You're in a fight with five times the normal amount of pressure on your body. At this depth, you'll also have to deal with some dangers. 

These are a few examples:

Reduced Visibility: Without your light, you can only see about six inches at this depth. This poses a threat because large predators, who are accustomed to hunting in the dark, are more likely to approach you when you're in the dark.

Longer Dives: Diving for an extended period increases your risk of blacking out losing consciousness. Aside from that, you'll have to equalize before ascending from such depths.

Large Fish: You dive to hunt rare fish, but you may find yourself the prey. Even though sharks cannot see you, they can detect your presence and come after you when you're not expecting it.

Diving isn't a precise science, and that's part of the fun. The depth to which a diver can go varies from diver to diver. However, most spearfishers stay within a range of 25 meters.

Furthermore, there isn't a set distance from the shoreline at which you can dive. Ultimately, it comes down to personal preference. You're just as likely to get into trouble at 200 meters as you are at 1 km.
