Ice fishing is one of the things that Northern anglers most look forward to each winter, and most anglers that do this would fish even if they did not catch anything. But there is no doubt that catching fish makes the experience a whole lot more fun. One of the things you can do to increase your chances of having a good catch is to bring a flasher — aka fish finder or sonar – along with you when you fish.

The ice fishing flasher is a sonar-enabled device designed to improve your odds of catching fish. They have a design that displays real time sonar so you can see the depth, if fish are passing through, where your lure is, and you can see how the fish are responding to your lure. They take a lot of the guessing, and waiting, out of fishing.

A good fish finder can make sure you are on the fish, instead of sitting 20 yards away from them while you catch nothing.

It is the ideal solution for ice fishing or people fishing from small vessels like kayaks or small fishing boats that have very limited amounts of console space.

What to look for in Ice Fishing Flashers

Reliability- You want an ice fishing flasher that is durable, and reliable. When you get out on the ice and turn your flasher on you want to know that the device is going to work properly. If you have to spend several minutes trying to get your device to power on properly, or if the machine powers off because it gets too cold, then it really is not benefiting you to have a flasher.

You can read the reviews of people who have actually purchased the items, and used the items, to determine the amount of reliability you can expect.

Lightweight – When you have to carry everything out on the ice where you will be fishing the weight of your equipment starts to matter a great deal. If your equipment is lightweight it is easier to carry, and it allows you to be able to carry a wider variety of items to use to your advantage.

Accuracy – Accuracy is of vitl importance. If the machine you are using is not accurate then you are simply using a device to make your best guess. You want a machine that has received excellent reviews from actual anglers that have actually used it. Those reviews will help you determine the real accuracy the device has.

Ice Fishing Flashers FAQ

Are larger screens better on ice fishing flashers?

Having a larger display screen makes it easier to see and identify what you are seeing. The drawback is that the larger screens drain the batteries faster, so the larger display screens may not be operational for the same length of time that the smaller display screen would be.

Can I use the same fish finder for ice fishing that I do for summer fishing?

Not recommended. The models listed above are all built with ice fishing in mind. With ice fishing, you need more durability, because the flasher will often be bumping around in a pickup bed or on a sled. You also need more portability, because unlike with a boat, you typically don’t mount is once and forget about it. You will bundle it up with your ice fishing shelter and other gear.  Finally, you need a stronger standalone battery life than a summer rig, because cold weather eats up your battery quickly and you don’t have a boat engine to feed the power from.
