The Original Trail Chasers GROUND MARKERS - Easy to Deploy, Easy to Move and Easy to Retrieve. Perfect for marking hiking trails, hunting locations, survey points, ground hazards, garden layouts, landscape designs, athletic fields, running courses, social events and more. The original Trail Chasers branded ground markers are highly durable 6 in. plastic whiskers combined with a lightweight non-rust stake that can be driven into the ground to mark a position. Unlike flagging tape and wire flags, Trail Chasers are highly visible, rugged, reusable, impervious to wind and dirt and will blend into most ground vegetation while still being easy to spot.
