How to Read a Flasher? Basic and Advanced Modes Explained - Ice Fishing Sonar

Ever wonder how to use a flasher for ice fishing? This video is a quick way to show you how to use one and some extra tips to get you more fish on the ice

Using an ice fishing sonar (flasher) can be confusing at first. In this video, How to Read a Flasher? Basic and Advanced Modes Explained - Ice Fishing Sonar, you will learn the basics as well as some advanced features to assist you being more efficient on the ice.

This video is using a Marcum sonar but, can be applied to all ice fishing sonars.

After placing the transducer into the water, set the RANGE dial to 20. If there is no return, move to shallower water or, turn RANGE dial to 40 or 80 until you see color on the flasher. (You should have the GAIN know set to about 4-5 to start).

Once a thick bands of color are seen, the part of the thick band of colors near the lowest number on the graph is the lake bottom.

Dropping a lure in the hole will result in the angler in seeing a small color moving clockwise as the lure drops. Setting the GAIN knob to a setting where the lure is a yellow color and is as thin as possible while still being seen. This is the optimal setting in most inland lake fishing.

Colors (for Marcum, check your manual for color meaning):
RED - Hard return. This can be sand or rocky bottom. This can also be fish that are near the center of the transducer.

GREEN - Medium return. This is often fish that are a few feet from the center of the transducer. Green can also mean that there are weeds off the bottom (especially if there is a thick red mark at the bottom of the green.

YELLOW - Weakest return. This is often fish near the edge of the transducer cone or thin weeds. A sudden appearance of yellow is most often a fish.

FISH: If the transducer is still and there is a mark moving from yellow-green-yellow, this is a fish moving in and out of the transducer range. If this mark changes to red, the fish is under your hole and hopefully looking to bite your lure.

For upgrades, lithium battery is my recommendation. They are lighter, charge faster and last longer on the water. Cold weather affects lithium far less than you standard SLA (sealed lead acid) batteries. I been using Amped Outdoors 12ah in the Marcum and it has lasted during many long days fishing.
