An underwater guiding device comprised of one or combination of a plurality of rigid guide segments, and/or telescoping guide segments where one or plurality of segments are of fixed length and one or plurality of segments are telescoping permitting use of either a single segment, a plurality of rigid guide segments for incremental extension of the assembly, and a combination of rigid guide segments and a telescoping guide segment or segments for sectional, infinitely adjusted, and dynamic extension and retraction of the guide assembly. The assembly can be secured to a stationary or moving work surface with static or dynamic control of individual segments, multiple guide segments, and assembly. The guide can be adjusted to any length and for any angle of operation. The guide is a method for guiding underwater submerged elongated structures through the water column into and through marine and other bottom surface, and subsurface materials.
