A fishfinder is a tool you can use to find fish. Sounds simple, right? They use sonar (echolocation) to send sounds into the water and detect whether or not there is something near your boat. Thanks to technological advances, many of these fishfinders have clearer images, and they come in either color or greyscale displays. Some even classify fish with different sized icons, or let you know if there’s debris under your boat. Fishfinders also come in various frequencies, and some are better for saltwater, while others are better for freshwater fishing.
Fishing on ice presents a different challenge, since many models aren’t suitable for cold weather. If you’re a fan of ice-fishing (or simply do it because you have no other choice thanks to the weather in your area), it’s best to purchase a fishfinder made especially for ice fishing. These will be made out of materials that are more suited to the cold weather, which can wreak havoc on ordinary fishfinder models.
Unlike other fishfinders, ice fishing fishfinders usually have a color code system to help you know what’s under your boat. You can also use models that use 2D sonar technology. These are older technologies than what you would use in other fishfinders, but they’re the only kind that will work in low temperatures. Take note: although you can carry a bigger fish finder on a bigger boat, it’s a good idea to have a smaller fish finder, since carrying heavy things in the snow can be a drag!
Cone size is important in ice fishing because you stay in one area. It’s important to use a wide beam so you know what’s around you as well as whats below you.
