Envco – Environmental Equipment

The chain features a “weak link” at one tow bar end - in this case, a “weak link” is good. If the sampler snags on what it is scraping up, the weak link snaps and alerts you to stop. You can usually retrieve your undamaged dredge easily.

The nylon net has 1” mesh openings and features a separate, heavy-duty nylon taffeta shroud around it for protection against snags. Tow arms fold for storage. Towing bridle pivots easily when the dredge is pulled over rough areas. Ship wt: 24 lbs. (11 kg)
