I have used all kind of ice-sonars over the years and I have come to appreciate being able to use one fishfinder both for my summer and winter fishing. Raymarine produced the Dragonfly Pro series that you could do just that. All you need to do is purchase the sonar which you can install on your boat and then to make it portable just purchase a “porta-pack” and ice-ducer.
In the image above you can see Mike Borovic working the Dragonfly 7Pro and leaving the right setting screen up so he can manually change the signal strength depending on the size of the lure he is using to try and entice Rainbow trout into striking.
If you’re in the market for a new all-season fishfinder, check out the Rayamarine Element Series and Ice Fishing Kit!
