What is the Difference Between an Ice Fishing Fish Finder and an Ice Fishing Flasher? 

Ice fishing flashers are one of the first and most commonly used electronic devices for ice fishing. There are traditional, stand-alone ice flasher units, along with units that incorporate fish finder and GPS functions, as well.

Flashers are merely portable sonar units that allow you to view what is going on beneath you under the ice through the use of a sonar beam that emanates from the unit.

An ice fishing fish finder works very similar to the types of units you would use on a boat. They vary depending on the available features but generally work the same. They have an external transducer that must be placed in the ice hole to read what is below you.

On the screen, a variety of colors represent different types of signals depending on the hardness of the objects below. A fish finder will not only just allow you to view the fish at different depths below you, but it will give you a glimpse into the habitat composition of the water column and lake bottom below you.

While a fish finder displays a variety of shapes below you, a traditional ice fishing flasher has a clock-like circle. This circle represents increasing depths in a clockwise manner. Shapes appear around this circle to indicate what is below.

Like a fish finder, different materials have different color representations. When an object is present in the field below, a color appears according to the object's “hardness”. Generally, green is a soft reading such as plants or fish, while red is a hard reading such as a rocky bottom. 

Flashers are designed for vertical jigging applications, and a key component for a flasher is the ability to detect even small jigs. This allows you to fish with your lure at the exact depth necessary.

The flasher also allows you to detect the holding depth of fish. Additionally, it enables you to see when a fish moves in order to check out your lure or jig and anticipate a potential strike.

Key Features of the Best Ice Fishing Fish Finders

A full-featured, all-purpose ice fishing unit should incorporate several types of functions. As discussed above, a full-featured ice fishing unit will be able to serve as both a traditional ice fishing flasher and a modern style fish finder.

Additionally, many of these higher end units incorporate GPS functions to help you keep track of important spots on the ice or in your boat.

A truly versatile ice fishing fish finder should incorporate all of the above. Having an ice flashing/fish finding/GPS unit will open up a myriad of opportunities for you.

It will also trim down your gear hoard by combining three units into one compact and convenient package.

Venterior VT-FF001 Portable Fish Finder,  Handheld Fishfinder Fish Depth Finder with Sonar Sensor Transducer and LCD Display


  • Compact Yet Powerful Unit on a Serious Budget
  • Able to Detect Fish and Structure Down to Over 300 Feet


  • Lacks Ice Flasher Setting
  • Lacks Much of the Performance and Capabilities Offered in Higher Priced Units

The Venterior Portable Fish Finder is a palm-sized, simple functioning fish finder. This is good for beginners on the tightest of budgets who may not be quite ready to jump into a more expensive unit. At a super-budget price, it is a quick sell, though be aware that it may lack the quality of some higher end units.

This device is able to detect rocks, weeds, and fish down to a depth of over 300 feet. The sensitivity of this unit only allows detection of fish within four inches.

This may not work for many ice-fishing scenarios when you need to be able to detect small lures and jigs. It also lacks an ice flasher feature best used in ice fishing and jigging scenarios.

Bottom Line

This portable unit lacks many of the features and precision of other units on the market. However, for the price, this device functions as intended for a fishfinder. If you desire a dedicated ice-fishing setup though, there are better options.

How to Use an Ice Fish Finder

For those unfamiliar with fish finders, they are quite simple and user-friendly. If you’ve previously used a traditional fish finder, using one for ice-fishing is hardly any different than using them on a boat.

You must first drill an ice hole into the ice to be able to hang the transducer in the water. At first glance, you should be able to see the lake bottom on your fish finder screen.

It will be a colored portion at the bottom of the screen and allows you to see how many feet of water there are below you. If your fish finder is sensitive enough, you should be able to drop your lure into the hole and see it pop up on the screen.

The shape and color of objects will vary by each unit. Fish will show up on the screen as a pre-specified shape and color. As the unit continually scans, you will be able to see any fish and whether or not they are reacting to your lure.

As discussed in the following video, a fish finder gives you a quick glimpse of the world below you. If you don’t see any fish on your screen after several minutes, consider moving to a new ice hole until you can “see” some fish to target.

Objects will appear differently on the screen depending on their size and “hardness” primarily. By familiarizing yourself with the owners manual and through hands-on use in the field, you will soon be able to read your fish finder like a book.

Watch the following video to learn how to use an ice fishing fish finder.


By now you should have gained a little more knowledge of ice fishing fish finders. There are a variety of features that you must choose from to select the perfect unit for you.  Thankfully, most modern units combine GPS, fish finders, and ice flashers all into one easy-to-use electronic unit.

When purchasing a unit, keep in mind the features that you will actually require and will put to use. Decide the amount of time your unit will spend on your boat vs. on ice to best select your unit.

Now it's time to make your decisions and get ready to start learning your way around your new ice fishing flasher for your upcoming fishing season.
