The electronic version of these operation manuals can be found at the following link. In the Fishfinder section, scroll down to HDR Series section. Unfortunately, we no longer have printed versions of these manuals.
Due to length of life of this product and the numerous changes in sonar technology, we can no longer repair these products, except for the HDR650. The HDR650 has been in production since 2010 and available today.
We no longer offer transducers nor mounting brackets for any models, except the HDR650.
