Our History

One of the first companies to make sonar depth finders.


Founded in the early 1970's, Fish Hawk Electronics was one of the first companies to make sonar depth finders (similar to the Lowrance Green Box.)


At that time, Pacific salmon were being stocked and taking hold in nearby Lake Michigan. Anglers quickly figured out that these exciting new fish were very sensitive to water temperature, and Fish Hawk introduced a temperature probe on the end of a cable with a line counter that told you temperature of the water at the depth of the probe.

As the Great Lakes salmon fishery developed, downriggers became popular and fishermen learned that underwater currents affected the action of their lures, making a big difference in their catch. Using sonar, Fish Hawk developed a probe that attached to the end of the downrigger cable and told anglers the water temperature and speed at their downrigger ball.


The first Fish Hawk Thermo-Troll systems were seen as space age technology at the time, and as the salmon fishery boomed, thousands of anglers put Fish Hawk systems on their boats. Various models of Fish Hawk Thermo-Troll Systems were manufactured from the late 1970's through 2005.

The current generation of Fish Hawk products are the result of four-decades of hard-earned fishing experience, combined with modern engineering, components, and precision assembly. We continue to produce the only wireless speed and temp system on the market today, and Fish Hawk Electronics are still proudly-built in the USA. A lot has changed in forty-plus years of fishing, but the importance of water temperature and trolling speed has not!

In 2009, Grayden Outdoor, LLC purchased Fish Hawk Electronics. As a family owned small business, we deliver personal service and work hard to make your limited fishing time more productive. We also manufacture and distribute Original Catch Cover ice fishing house products.© 2015 Fish Hawk Electronics, All Rights Reserved
