DGX Ultra-Viz™ Retroflective Line on Bulk Spools
- Round braided polyester line that features a retroreflective stripe
- Line diameter of approximately 1.8 mm
- Engineered high-tech product with exceptional strength, abrasion and UV resistance
- Vibrant blaze orange and florescent yellow-green colors will not run or bleed
- Our bulk spools are mostly cardboard made from recycled paper
Recently introduced, our new DGX Ultra-Viz™ Retroflective Line is round braided polyester and includes a retroreflective nylon strand impregnated with tiny glass micro-beads (<100 microns) that makes the already vibrant line even brighter. Similar to the way SOLAS tape works, when light shines on the reflective strand the light retroflects back toward the source of the light.
Custom manufactured for Dive Gear Express, our DGX Ultra-Viz™ Retroflective Line is high-tenacity, abrasion and UV resistant line that also resists twisting or kinking and has minimal stretch. The line has negative buoyancy in both fresh and salt water. Traditional white nylon line used on reels is difficult to see in open water, but our Blaze Orange and Florescent Yellow-Green colors stand out like neon, allowing easier line management with nearby divers. The durable color of our Ultra-Viz line also remains vibrant over time, unlike the "wash-out" fading typical of ordinary nylon cave line that has been dyed orange. We also offer a Super White color which includes the retroreflective stripe.
The technical specification for the diameter of our DGX Ultra-Viz™ line is approximately 1.8 mm which does not fit nicely into the archaic 'twine' size code numbers that might be familiar to long time cave divers. Describing the diameter using size codes, the line is somewhere between #21 and #24. Regardless, the 1.8 mm polyester line in water is stronger than #36 nylon and thinner than #24 nylon so you will be able to load plenty of extra on the reel.

Customer Reviews
Orange or Yellow, which is better?
There is no easy answer; both are good choices for improved visibility. Different colors are seen to differing degrees by the human eye, meaning people are more sensitive to some colors than others. Peak sensitivity is at portion of the visible spectrum where yellow transitions to green. With that in mind, most people will have the highest sensitivity to a fluorescent yellow-green color (aka chartreuse, greenish-yellow, neon green) just by the nature of how the human eye sees colors. Fluorescent yellow-green is somewhat more visible in dim light due to the Purkinje effect, however the blaze orange color is still on the brighter end of the spectrum making it highly visible too. Blaze orange also provides more contrast with some backgrounds, especially those common to diving. Another thing to consider is there are an estimated 300 million people with some degree of color vision deficiency - most of whom are male; about 1 in 12 men are color blind (8%). Color vision deficient individuals may better perceive blaze orange due to contrast. The choices of blaze orange and florescent yellow-green have been extensively studied by human factors experts for applications such as transportation signage and high-visibility clothing.
