The NARDA Probes will need to have the capabilities to preform jobs specific to bioenvironmental surveys and assessments. The probes should be durable to insure they withstand the environment in which they will be used in. To ensure minimal ergonomic stress, the probes should be light weight and easy to maneuver when used in surveys. Probes should also be able to read in the correct frequencies when surveys are performed. See Statement of Need (SON).
