The Ponar Samplers, or ‘Grab Samplers’, are widely used in fresh and salt water for taking sediment samples from hard bottoms such as sand, gravel, consolidated marl or clay. This sturdy dredge is available in two sizes – Petite Ponar for shallow samples and easy handling, or the Standard Ponar for bigger jobs that require extra weight.
Petite Ponar Sampler:
Constructed from stainless steel, this bethic sampler gives a whole new meaning to the word “petite.” At just 6.8kg, the Petite Ponar Sampler can easily be carried by one person in the field and can be depolyed without the use of a winch or crane recommended for larger samplers.
Standard Ponar Sampler:
The Standard Ponar is deliberately heavy device for biting deep into the bottom and has proven success at invertebrate recovery. When the scoops strike the bottom, their tapered cutting edges penetrate well with very little sample disturbance. Removable screens on top of each scoop allow water to flow through as - Stait descends. Constructed of 316 Stainless Steel and weighing 34kg when full, it is recommended that a crane and winch is used for deployment due to working weight.
