How Much Weight Do You Need for Spearfishing?

Spearfishing is an exciting and rewarding way to catch fish. With its roots in ancient hunting methods, it is one of the oldest forms of fishing we know of today.

It’s also one of the most efficient, as it requires minimal gear and you can hunt for a wide variety of fish species. However, one important factor to consider when practicing spearfishing is just how much weight you need.

The amount of weight you need for spearfishing depends on a few factors, such as the type of fish you are Targeting, the type of water you are in, and your own body weight. Generally speaking, the heavier your body weight is compared to the water you are in, the more weight you will need. That’s because most spearfishers use a combination of their own weight and weights attached to their bodies to sink down in the water column and reach deeper depths.

When it comes to Targeting larger fish species such as tuna or marlin in deep open water, additional weights can make a huge difference in your ability to remain submerged long enough to make an effective shot. For these types of dives, a total weight ranging from 10-20 pounds may be necessary depending on your individual body size.

For more shallow dives or when Targeting smaller species such as redfish or snapper in inshore waters, less weight may be required. A total combined body/weight load around 5-10 pounds should be sufficient for most people. This is especially true if you plan on doing multiple dives during one outing since lighter weights will be much easier on your body during long days out on the water.


The amount of weight needed for spearfishing will vary depending on the type and size of fish you are Targeting as well as your own body size and the depth of water that you’re diving in. Generally speaking, heavier weights are required for deeper dives while lighter weights may suffice for shallower inshore dives. Ultimately it’s important to experiment with different amounts so that you can find out what works best for each individual situation.
