From time to time I get a call or email from someone who has an old Impulse fish finder or Loran-C receiver, and needs an owner’s manual. If you have one of the Impulse models below, click on your model number to download a manual. I’ve provided both high-resolution and low-resolution versions of each manual, in case you value bandwidth more than quality.
If your Impulse product is not listed here, I’m sorry, but I don’t have a manual for it.
