Artificial
Substrate Cone
The cone's height is 10 inches and its base is 10
inches. The bottom pan has an oversized 200 micron
mesh nylon pad to prevent "wash out". The bottom
fits inside the cone's base and is held in place
with four nylon releasable ties. The two
circumferences are covered by PVC welting for
protection from the wire ends. The cone is used for
deep water sampling in rivers and lakes.
The Retrieval Funnel is designed to work with the
cones. The "funnel" is constructed out of 16 ounce
copper and is evenly weighted with four weights. The
funnel covers the submerged cone during retrieval to
shield the cone from wash out.
