The device is not just for running and gunning ice but is designed to help anglers find and locate fish hidden in the Ice. It comes with a 20-degree transducer, has a power of up to 4000 watts and comes with a 2-inch target separation feature.

The unit has 25 sensitivity settings, 120 –foot range auto depth scale function, ten noise setting sand and an automatic bottom lock zoom. It is one of the finders that can run continuously on 8 AA batteries and come with an Ice- mode which activates internal heater to aid the LCD in extreme conditions.

Product Features


The power of a finder is an important factor that determines whether the device helps you in your ventures or not. Note that the units power output is more critical if you plan to fish in extremely difficult conditions. The MarCum Showdown Troller 2.0 has a power rating of 4000 watts peak to peak power which allows the unit to display the reading at a click of a button. It is an ideal finder for anglers who love fishing in icy areas.

The device can translate the sonar waves from the transducers in real time. The readings are displayed on a 5” screen which makes it easier for the angler to pursue his prey with certainty. It makes the device the best for anglers who prefer to troll from hole to home. Even though, it can be used in open waters and can help discern the correct depth of the fish.

Screen Resolution:

The number of pixels the screen finder displays allows the angler to have more details of what is happening in the water. It determines the number of dots that can be displayed in each row and column. 

The greater the pixels, the more detailed the images will be. The new MarCum Showdown Troller 2.0 is newly upgraded and comes with new LCDs that give it the sharp resolution that enables it to display the structure, the fish, and the lure as they are.

The device comes with an Auto Bottom Lock Zoom feature that magnifies anything near the lure and eliminates chances of missing out even on a bottom hugging fish. The images received on the screen are blocky, sharp and crisper. It is a high-resolution screen that makes the device worth investing in.


Ideally, the work of a transducer is to emit and receive sonar waves. The emitted waves will bounce off objects underwater and will be sent back to the transducer and get converted into pictures, which are displayed on the screen. The new MarCum Showdown Troller 2.0 features a 6-foot, 20 degrees transducer capable of emitting signals with a frequency of 200 kHz.

This is a highly sensitive sonar unit that allows the angler to read anything including tiniest solids at the bottom. If the sensitivity is well set, it allows the angler to view the lure and the surrounding. It is also capable of turning out the excessive clutter in the area. However, the clutter can be made to disappear by decreasing the sensitivity level to enable the angler to read moving items below the transducer.

Cone Angles & Beams:

The cone angle is important to anglers because it determines how wide the beam is sent from the bottom of the boat. Luckily, the new MarCum Showdown Troller 2.0 comes with a 20 Degree transducer that gets wider and covers more area deeper and deeper. The 20 –degrees cone makes the unit ideal for anglers who fish in waters with different depths.

When the transducer is placed in an ice hole, it levels itself and displays the water depth including weeds and fish that are present in the area.

It also enables the angler to get the best reading to make a move. Note that the angler is free to decide whether to have the dual, side beam or triple beam, depending on his experience.


The new MarCum Showdown Troller 2.0 comes with a high-frequency transducer. It emits and receives signals at 200 kHz which makes it suitable for shallow waters. It is ideal and can help anglers identify fish in icy water.

At 200 kHz, more details are sent to the screen and prepare the angler to determine the type of fish found in the mapped area. The frequency is high enough and eliminates any interference. However, if you get interference from adjacent electronics, all you need to do is adjust the noise rejection feature and clear off the interference.


If you are an ice angler, you need a device that can help you map out the area rich in the species of fish you want to catch.

Consider buying MarCum Showdown Troller 2.0, which is portable and convenient to carry. MarCum Showdown Troller 2.0 is not just easy to use, it is clear, accurate and cheap.
