Keeps Flies Shallow with Slow Retrieves.
Stillwater trout fishing demands precision depth control, subtle presentation, and the ability to target feeding fish anywhere from the surface film to deep in the water column. Engineered specifically around these requirements, Scientific Anglers’ Stillwater Series offers specialized fly lines designed to search, present, and entice trout in lake environments.
Lines in this family feature AST Plus slickness for easy shooting and durability. Seamless
Density transitions to eliminate hinge points, which create a direct connection to the fly,
and Sonar Technology to maintain consistent depths.
- Revolutionary AST Plus slickness additive for superior shooting ability and increased durability
- Designed specifically for the demands of stillwater anglers
- Overweighted by two line weights for multiple flies, long leaders and longer casts
- Textured hang markers 10 feet and 20 feet from the tip
- Hover features an ultra-slow, (0.5 ips) almost neutrally buoyant line that keeps flies just beneath the surface, breaking the surface film for subtle, natural presentations in calm or pressured conditions

ADVANCED SHOOTING TECHNOLOGY PLUS
The revolutionary AST Plus slickness additive produces the slickest fly lines on the market, period. Fly lines with AST Plus are 50% slicker than lines with our old AST slickness additive, and nearly 70% slicker than the closest competitor. The reduction in friction results in longer casts, easier pick-ups off the water, and lines that last longer than ever before.
AUDIBLE REFERENCE POINT
The Audible Reference Point is the inverse of the Tactile Reference Point. It’s an embossed section of line where the head meets the running line, allowing you to hear that transition as you strip in line.
SCIENTIFIC ANGLERS LINE IDENTIFICATION (SA•ID)
SA brings you SA ID. SA ID is an innovative line marking system allowing you to identify your lines at a glance. Wonder if a shooting head is 200 grain or a 300? Just look at the SA ID.
WELDED LOOPS
Exceptionally slick and strong, welded Streamlined Loops produce smoother casts and easier turnover with a seamless fly-line-to-loop transition making for softer landings and cleaner pickups.
CAMO
Camo technology creates a stealthy blend of muted colors on fly lines, providing much-needed stealth for wary fish, low-water situations, and any time an additional bit of deception is necessary.
SONAR
For every one fish eating on top, there are ten feeding beneath it. SA's SONAR sinking technology takes flies to where the fish are: beneath the surface. Using proprietary tungsten formulations and unique tapering, the SONAR sinking technology gets flies down, and keeps them there.
