Frequently Asked Questions (FAQs)

1. Is monofilament line good for saltwater fishing?

Yes, monofilament line is a good option for saltwater fishing. It is thin, strong, and has good knot strength. It is also more abrasion-resistant than braided line and stretches more, making it suitable for saltwater fishing.

2. What size monofilament for saltwater fishing?

For general saltwater fishing, a 6 to 7-foot medium-action offshore fishing rod with a heavy baitcaster reel and 20-pound test monofilament line is sufficient. However, if you are going for deep-sea bottom fishing, you may need to use 50-pound line.

3. What pound line is best for saltwater fishing?

For saltwater fishing, the standard pound test is usually 30 or 50 lb. Anglers use lighter pound tests with monofilament line to maintain casting ability and keep a suitable amount of line on their spools. In freshwater, a 4-12 lb test is standard.

4. What are the cons of monofilament line?

While monofilament line has many advantages, there are a few drawbacks. It is not as durable as braided line and has a thicker diameter, limiting the amount that can be spooled. It also doesn't last as long as braided line.

5. What color line is best for saltwater fishing?

For saltwater fishing, clear is the number one option, as it provides superior clarity. Green and blue are also good choices as they retain their color even at deeper depths.

6. Is there a difference between saltwater fishing line and freshwater fishing line?

Yes, there is a difference between saltwater and freshwater fishing lines. Freshwater lines are typically made with larger diameters and lower line density to improve floatation, while saltwater lines are designed for the specific demands of saltwater fishing.

7. Is 20 lb mono good for surf fishing?

A 20-30 pound test monofilament line is generally suitable for surf fishing situations with smaller fish like surfperch, bluefish, or striped bass. However, if there is a chance of hooking into larger fish such as sharks or tarpon, it is recommended to use a setup with 50-80 pound test line.

8. What pound line is best for beach fishing?

The best pound test for beach fishing ranges between 15 and 20 lbs when using monofilament line, and between 30 and 40 lbs when using braided lines. The choice of pound test depends on the size of the fish you are targeting.
