We offer consultations, at no cost, to discuss your project and needs. We have technical expertise in nearly all facets of fisheries telemetry and are happy to share what we’ve learned over the years. We are not a manufacturing company and thus are not bound to a particular product or vendor. This allows us to have tremendous flexibility in project design and to implement technologies where appropriate. For example, in one study alone this season we are using equipment from Lotek, HTI, Biomark, Teknologic, and InterOcean Systems to provide answers to a very complex question on the Columbia River. We are a leading source of knowledge in the industry and we are always willing to share that knowledge. If you are considering a study please drop us an email or give us a call.
