Ponar Grab Samplers

Ponar ‘Grab’ Samplers

Overview

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.
