There are a few important things you always want to remember when you buy a fish finder for ice fishing:
When choosing a fish finder for ice fishing(especially useful if you live up north in Canada or Northern Europe), portability is key – you don’t want to lug something inconveniently sized through snow and ice!
The next most important thing to think about is the battery. Your main unit could be moderately sized, but if you have to carry a huge battery just to power it, it destroys the point.
You need a battery that is both small but powerful enough to keep your ice fish finder going for an extended time, so you only have to worry about how many fish you catch, and nothing else!
The major manufacturers all offer special ice fishing packages, so they take care of most of the worrying for you. Humminbird offers a range of special fish finders meant specifically for ice fishing and ice fishing only, with a portable battery pack, transducer, all zipped up in a neat pouch that you can carry easily.
How Ice Fish Finders Work
There are two ways an ice fish finder can find out what’s underneath you. Unfortunately, no one device does both – you will have to choose between one or the other, depending on what is most convenient for you. There are flasher units, which do not show a graph of the details below, but only show a real time look at what’s there.
Even though this is an older technology, it’s still an extremely reliable way to look at the bottom and everything in between. This is the best option if your only use for it is going to be ice fishing, but sometimes reading the display takes a little getting used to.
The other option is to go with 2D sonar. This is a great alternative to the flasher as many of these units can show a graph of what is happening below, or switch to a flasher mode with emulates the look of a flasher unit.
This is the best option as it gives you the best of both worlds, and allows you to compare what you see between both options. Additionally, it also allows you to use the unit for fish finding in the summertime. With a little planning, it’s really easy for you to switch the unit from your boat to a portable packet in the wintertime.
You should be aware though that most compact 2D units will not have a flasher option, so you are stuck with only a normal graph.
Sonar Angle or Cone Size
Since you are stationary in ice fishing, the cone size of your sonar beam will play a huge role. A wider cone can show you much more detail, since it won’t be just of what is directly beneath you, but also of what is all around you. Use it to your advantage!
Cheap Ice Fishing Flashers
HawkEye FT1Pi FishTrax 1X IceShack Kit
While there has been an increase in cheap fish finders lately, they don’t have the quality that well known manufacturers pride themselves on delivering. Of the current offerings in ice flashers, the HawkEYe FT1Pi Ice kit is a solid choice for a very, very reasonable price.
It’s basically the FishTrax 1 bundled in a handy yet rugged carry case which makes it an excellent portable fish finder as well as ready to take out on to the ice.
This is the fish finder itself, which comes with a transducer you’ll have to lower into the hole you’ve cut into the ice. It works a little different than other proper flashers where you could just put the transducer on the ice before you cut the hole.
For the price, though, this is a steal, considering you’d have to spend 2-3 times more to get a proper ice fishing unit. If you’re held back by your budget, go for this.
Garmin Striker 4 Portable
Since we’re looking at cheap options, the Garmin Striker 4 portable is a step above the Hawkeye, but still not a dedicated Ice flasher. It’s more of a fish finder adapted to an ice fishing flasher.
Still, by itself, the Striker 4 is an awesome unit, with dual frequency CHIRP sonar which will give clear returns whether you are fishing from a boat or on the ice.
For a better idea of ice fishing, you can use the flasher mode where the screen will change from a regular fish finder SONAR returns screen to a flasher screen for a more traditional ice fishing experience.
The advantage of this fish finder is that it will double as a regular portable fish finder during the summer months and as an ice fishing finder during the winter months.
