Daiwa J Braid Grand X8 Review: Strength, Diameter & UV Test

This review examines the Daiwa J Braid Grand X8 fishing line, specifically the 16 kilogram (35-pound test) line with a purported 0.20-millimeter diameter. We subjected this line to a series of tests to assess its performance characteristics, including diameter verification, breaking strength, and UV reactivity. Our findings revealed several inconsistencies between the manufacturer's claims and our observed results, prompting a closer look at the accuracy of the product labeling. The tests focused on evaluating the line's handling, strength under tension, and its visibility in low-light conditions.This in-depth analysis covers key aspects crucial to any angler considering this braided line. We measured the actual diameter, performed multiple breaking strength tests to determine the line's real-world capabilities, and assessed its fluorescence under UV light. The results offer valuable insights into the line's strengths and weaknesses, providing a comprehensive assessment that goes beyond the manufacturer's specifications and allows anglers to make an informed purchasing decision.

Pros And Cons

Daiwa J-Braid Grand X8 Fishing Line
  • Practically no line memory
  • Incredible strength for its advertised diameter (broke at 11kg instead of advertised 16kg)
  • Does not glow under UV light
  • Broke at a lower weight than advertised (11kg instead of 16kg)

Line Specifications and Initial Impressions

The Daiwa J Braid Grand X8 fishing line, specifically the 16 kilogram (35-pound) test, 0.20-millimeter diameter version, was the subject of this review. Initial observations focused on the line's lack of memory, a common advantage of braided lines. This characteristic makes it easy to handle and cast.

Interestingly, using a caliper, the measured diameter was 0.12 millimeters—significantly thinner than advertised. This discrepancy raises questions about the actual strength of the line.

UV Light Test and Results

Many braided lines exhibit fluorescence under UV light. This feature aids in low-light visibility. However, the Daiwa J Braid Grand X8 did not glow under a UV torch. This is a notable drawback for anglers who rely on this feature for nighttime fishing or in murky water.

The lack of UV reactivity is unexpected and could be a product defect or design choice. Further investigation is necessary to fully understand this aspect.

Breaking Strength Test

The advertised breaking strength is 16 kilograms (35 pounds). The initial break test resulted in a failure at 8.8 kilograms at the knot. A second test, focusing on the line itself, resulted in a break at 11 kilograms (approximately 24.25 pounds).

While significantly lower than the advertised strength, the 11-kilogram breaking strength is still reasonably strong for a line of this supposed diameter. This could be influenced by the thinner-than-advertised diameter.

Conclusion and Recommendation

The Daiwa J Braid Grand X8 exhibited some inconsistencies. While its lack of memory and relatively high breaking strength are positive features, the thinner-than-advertised diameter and lack of UV fluorescence are significant drawbacks. The substantial difference between the advertised breaking strength and the tested strength raises concerns.

Overall, while the line performed reasonably well, the accuracy of the labeling is questionable. Anglers should carefully consider these factors before purchasing, and perhaps seek verification on actual diameter and breaking strength from other sources. The UV glow aspect is entirely absent.
