How to Choose an Ice Fishing Flasher


The first thing to look for in an ice fishing flasher is power and wattage. Higher power offers better and more efficient performance. It also improves the chances of your fish finder finding fishes that lie deep below the ice surface.


This is something you should know about if you’re serious about ice fishing. It is designed to emit sonar waves that bounce off the body of fish and give you feedback in form of a picture on the screen. Consider choosing a flasher with a good quality transducer. Some manufacturers incorporate a transducer holder. In such a case, it’s important to ensure that the holder system can accommodate different transducer sizes.


You won’t be able to bring the car all the way to your favorite fishing spot. As such, any gear and equipment should be compact and lightweight for better portability. The last thing you need is getting exhausted before you start the actual fishing part of the ice fishing excursion.

Cold weather tolerance

Because you are going ice fishing, choosing a flasher designed for cold weather is certainly crucial. Usual flashers that mount on boasts can get damaged internally if subjected to sub-zero temperatures. Many companies use patented technology to make their products more durable in cold weather. Look for models with low-temperature ice transducers.

Cone size

Be on the lookout for ice flashers that detect what is beneath the surface and around you. Generally, the larger the cone size, the more coverage you will get. This gives you a much-needed advantage while fishing.


No one wants to go on a fishing excursion if they will spend most of the time charging gadgets just to use them. Go for an ice fishing flasher with a long-lasting battery that will keep you going for extended hours.

Backlit display

Low light is a common issue when it comes to ice fishing and as such, going for a flasher with a backlit display is always a good idea. Speaking of screens, the resolution directly impacts the quality of images displayed.
