Overview

Built for river back-trolling, this diver uses water pressure against its wings to get down and then float off structure when pressure eases. It is intended to help present lures and baits tight to the river bottom, where controlled depth and contact matter. The 4-inch body is rated for a running depth of 40 feet and comes in Purple UV Moon Jelly. For anglers working current seams and structure, it offers a focused approach to subsurface presentation without unnecessary complexity.

Considerations & Trade-offs

  • Designed for river back-trolling, so it is more specialized than a general-purpose trolling diver.
  • The 40 ft. running depth is a stated specification, but actual depth will vary with water pressure, speed, and setup.
  • Its buoyant design is intended to float off structure when pressure relaxes, which may not suit presentations that need constant bottom contact.
  • The Purple UV Moon Jelly finish is a specific color choice, so anglers looking for a more neutral profile may prefer a different option.
