MarCum TECHNOLOGIES M1 3 Color Ice Sonar

Product Information

Specifications

• Product Name: M1 3-Color Ice-Sonar
• Manufacturer: MarCum
• Website: www.MarCumtech.com

General Description

The M1 True Color sonar unit utilizes three different colors within its display to differentiate between densities of objects: RED, ORANGE, and GREEN. The use of different colors in defining return signals is meant to be informative in indicating the size of fish, type of bottom or location of weeds. The interpretation of these signals improves with experience and use in the field.
The M1 offers multi-level Interference Rejection (IR) from nearby competing units. This is most prevalent in ice-fishing applications where anglers utilizing sonar are often grouped together within small areas.
Your MarCum is water and weather-resistant and is designed to be used in the outdoors, but in extreme weather conditions, care should be taken to shield the monitor from driving rain and boat spray. At no time should the monitor be in direct contact with large amounts of water. Should your M1 become wet, it is unlikely that any harm will come to it, but make sure to get the entire system completely dried out as soon as possible.

Battery Charging

For safety reasons, it is recommended that you place your system on a flat, hard surface like cement or tile when charging it, away from any flammable materials. Be sure to disconnect the charger from the wall when not in use, and avoid leaving your battery hooked up to the charger for extended periods of time.

To charge your battery:

1. Ensure your system is placed on a flat, hard surface.
2. Connect the charger to the wall outlet.
3. Connect the charger to your system’s battery.
4. Allow the battery to charge fully.
5. Disconnect the charger from the wall outlet and the battery.

If you are having difficulty with the charging process, please refer to the Troubleshooting section on our website, www.marcumtech.com/support.

Ice System Set-Up

Setting the Transducer for Ice Fishing:
To set up the transducer for ice fishing:

1. Select a suitable location on the ice for fishing.
2. Ensure the ice is reasonably clear.
3. Wet the ice with at least a cup of water to improve the coupling of the transducer to the ice.
4. Place the face of the transducer firmly on the wetted ice.
5. You will now be able to see the depth and fish displayed on your dial.

Moving the Transducer to a New Location:

If you need to move the transducer to a new location:

1. Lift the transducer from its current position on the ice.
2. Select a new location on the ice for fishing.
3. Wet the new location with water.
4. Place the face of the transducer firmly on the wetted ice at the new location.

Reading Through Ice:

The M1 will provide accurate information reading through ice providing the ice is reasonably clear. Wet the ice with at least a cup of water to improve the coupling of the transducer to the ice. Place the face of the transducer firmly on the wetted ice, and you will now be able to see the depth and fish displayed on your dial. Drilling into the ice 1-2 inches before taking a reading may be necessary if the surface of the ice is very rough or if the ice is filled with air bubbles.

Operation

The M1 utilizes a combination of control knobs (Gain & Range) and keypad (IR) and (ZM) to change or activate various system functions. The keypad has an audible beep when the key is depressed to indicate that a system function has beenactivated.

General Description

• The M1 True Color sonar unit utilizes three different colors within its display to differentiate between densities of objects: RED, ORANGE, and GREEN. The use of different colors in defining return signals is meant to be informative in indicating the size of fish, type of bottom or location of weeds. The interpretation of these signals improves with experience and use in the field.
• The M1 offers multi-level Interference Rejection (IR) from nearby competing units. This is most prevalent in ice-fishing applications where anglers utilizing sonar are often grouped together within small areas.
• Your MarCum is water and weather resistant and is designed to be used in the outdoors, but in extreme weather conditions, care should be taken to shield the monitor from driving rain and boat spray. At no time should the monitor be in direct contact with large amounts of water. Should
• your M1 become wet, it is unlikely that any harm will come to it, but make sure to get the entire system completely dried out as soon as possible.

BATTERY CHARGING

• Your MarCum system comes with a 3-stage battery charger. This style of charger has proven to be the most effective and easiest to use of all charging systems available. Because this is a 3-stage charger, there is no danger of overcharging your battery. When properly cared for, a sealed lead acid battery will last for at least a couple of years. Batteries are made to be used, and they need to be used to make the most of them. The most important thing you can do is to prompt-ly recharge your battery after each use. Not charging your battery immediately after use is the number one thing that leads to battery failure.
• For safety reasons, it is recommended that you place your system on a flat, hard surface like cement or tile when charging it, away from any flammable materials. Be sure to disconnect the charger from the wall when not in use, and avoid leaving your battery hooked up to the charger for extended periods of time.
• When you get home from a trip, put your battery on charge right away and leave it there overnight, or for around 8-12 hours. Likewise, on the night before an ice fishing trip, put it on the charger again, just to make sure. Again, there is no danger of overcharging your battery. We often talk to people who hesitate to charge their battery after each use for fear that the battery will develop a “memory” and this will lead to a shortened run time—THIS IS FALSE!!! ALWAYS CHARGE YOUR BATTERY AFTER EVERY USE!!! Be sure to use the charger that came with your system, or a similar one that is between .5 amp and 1 amp. Using a larger charger, like you would use on a car, truck, RV, or boat is likely to cause damage to the battery. There is really no danger of overcharg-ing your battery with a low amp charger, and most chargers automatically go into “maintenance mode” once a full charge has been achieved.

TO CHARGE YOUR BATTERY:

• Your battery has a wiring harness attached to it that has “piggyback” terminals on it, enabling you to keep the power cord from the unit attached to the battery always, as well as having the wiring harness with receptacle for your charger attached always. To charge, simply couple the end of the charger with the end of the wiring harness. It is normal for a green light to appear on the charger now if the charger is plugged into the battery only. It is also normal for the light on the charger to be green if it is just plugged into the wall. When it is plugged into the wall and battery, you will see a red LED light appear on the charger. If the light is red, the battery is being charged. When your battery is fully charged, this red light should change to green. If it is time to go fishing and the light has not turned green, go fish and try to allow a longer charging period next time.
• Batteries are an expendable item, and must be replaced periodically. The batteries that we use are the “Sealed Lead Acid” variety, they are 12 volts, and range from 7 to 9 amps. The more amps the battery has, the longer it will run on a full charge. Your MarCum can be powered off any battery that is 12 volts, even a large automotive or deep cycle battery.
• If you are having difficulty with the charging process, please see the Troubleshooting section on our website, www.marcumtech.com/support .
• If you need to remove the battery, slide the power cord leads from the battery. Remove the strap that is holding the battery in place and lift the battery out. To replace the battery, place a new battery of similar specifications into the battery compartment and secure it with the Velcro strap and re-connect the positive and negative terminals.

Ice System Set-Up

Your M1 comes virtually ready to fish. All you need to do is hook up the positive lead from the M1 power cord to the battery. Your M1 is delivered with a charged battery, so you can take it fishing right away. Inside the M1 deluxe softcase is an electronics shuttle that has recessed compart-ments for the battery and the single beam transducer. Take the transducer out of the recessed holder and rotate the adjustable ice arm out from inside the shuttle. The adjustable ice arm allows for maximum flexibility in positioning the M1 around the ice hole.

SETTING THE TRANSDUCER FOR ICE FISHING:

• When used in conjunction with the retractable pivoting transducer arm and rubber stopper, the M1’s transducer will automatically level itself in your ice hole. To begin operation, take the transducer out of the recessed holder, and rotate the adjustable ice arm out from inside the shuttle.
• Extend the transducer arm, (the cable should already be threaded through it with stopper in place) and deploy the transducer into the water. We recommend setting your stopper to have the transducer down the least amount possible. The MarCum M1 puts out enough power that in most cases it is not necessary to have your transducer down more than a few inches below the water line to get a good reading.
• When the ice thickness is over two feet, it may be necessary to have your transducer set somewhat farther down. Remember–the less transducer cable you have out, the easier it is to pull it out of the water when bringing in a fish, or to move to a new location.
• Under no circumstances should you ever have the ducer below the ice—this can lead to the ducer becoming damaged. It is also important that you keep the cable near the center of the ice hole.
• We frequently hear from anglers who allowed their cable to freeze into the side of the ice hole. If this should happen to you, make sure the unit is turned off before attempting to chisel it out. If you accidentally cut the ducer cable, do not try to use that ducer again.

MOVING THE DUCER TO A NEW LOCATION

Being mobile is one of the keys to being successful on the ice. Whenever you move from one spot to another, it is tempting to leave your transducer hanging on the transducer arm. This is likely to lead to failure of the transducer arm, and can cause damage to the transducer itself. Always stow the transducer inside the pack when you are moving. Keeping the amount of transducer cord you have out at a minimum will make transporting your M1 easier. Similarly, you may need to quickly remove your transducer from the hole when about to land a fish. We have seen anglers in a panic grab the shuttle itself and toss the entire unit to the side. This is no way to treat any piece of electronics; a much better approach is to simply lift the transducer out of your way by the cord, and the shuttle itself can be gently pushed aside. Whenever you are moving via sled or vehicle, always fold up your transducer arm, stow the transducer inside, and close the protective soft pack.

READING THROUGH ICE

The M1 will provide accurate information reading through ice providing the ice is reasonably clear. Wet the ice with at least a cup of water to improve the coupling of the transducer to the ice. Place the face of the transducer firmly on the wetted ice, and you will now be able to see the depth and fish displayed on your dial. Drilling into the ice 1-2” before taking a reading may be necessary if the surface of the ice is very rough, or if the ice is filled with air bubbles.

Operation

The M1 utilizes a combination of control knobs (Gain & Range) and keypad (IR) and (ZM) to change or activate various system functions. The keypad has an audible beep when the key is depressed to indicate that a system function has been activated. The following is an explanation of the various system functions.

Range Select

The Range select knob is used for turning the M1 on or off, as well as choosing the correct depth range. The M1 offers four depth ranges to choose from that can be selected by rotating the knob clockwise. The depth ranges are 20, 40, 80, or 160 feet. The depth-range setting is determined by turning the unit on and turning the Gain knob looking for a solid return (band of light) indicating the bottom on the display. If no return is present, then select the 40-, 80-, or 160-foot range until a bottom reading is displayed on the screen.
Interpreting the different rings of numbers around the dial When on the 20’ range, simply go by the white numbers. When on the 40’ range, use the outer white numbers, but multiply x 2 to determine your depth [13 on the dial = 26 feet]. When on the 80’ range, use the red numbers. When on the 160’ range, use the red numbers x 2. The innermost numbers are for the split-screen zoom, and they are used similarly.

Gain Knob

The Gain knob controls the amount of sensitivity required by the unit to pick up objects like bottom, weeds, fish, smaller bait fish, or small lures and jigs. The lower the number, the less sensitivity, conversely higher numbers mean more sensitivity. However, too much Gain (sensitivity) will result in too much information being displayed, and it becomes difficult to interpret the return signals. The best Gain setting is achieved by turning up your Gain from 0 until you receive a clear and steady bottom reading. If you’re looking for your lure or bait, turn up the gain until you just begin to display your bait without it fading or flickering on the screen. The lower the sensitivity, the narrower the display segments, the easier it is to distinguish targets. We cannot emphasize this strongly enough. Too much Gain will only clutter the display with unnecessary information, making it more difficult to interpret the return signals. Keeping the Gain at minimum levels will provide you with the most accurate and precise information.

Interference Rejection

The Interference Rejection system is designed to knock out competing return signals from other sonar units being used within proximity. When other sonar units are causing interference to the display of the M1, activate the IR feature by depressing the IR key located on the face of the M1. When you press the key, a beep will be heard. There are multiple levels of interference rejection, and each press of the key will change the level of Interference Rejection. The correct level of IR will be achieved when the display is clear of display clutter. In some extreme cases, clutter will be greatly reduced but not eliminated. It is recommended that only one person in a group adjust the interference rejection at a time.
Zoom – The M1 is equipped with a “bottom zoom” feature. When the ZM key is depressed the circular display is divided in half. The right half of the display (12 to 6 o’clock on the dial) will become the entire depth range (20, 40, 80, or 160 foot) you chose when turning the depth range knob to your desired depth setting. This will be indicated by a red light at the zero mark (12 o’clock) and another red light at 6 o’clock. These will be stationary and will not move while in the Zoom mode. The backside of the display (6 to 12 o’clock) is the other half of your split screen display. This is the Zoom window portion. The M1 comes with a bottom zoom that displays the bottom 5 feet in an expanded view. This expanded view of the bottom 5 feet is what is displayed on the left side of the split screen display (6 to 12 o’clock). For the Zoom to be activated, you must have a strong bottom return signal (Red) that equals or exceeds one foot on the display dial. If a strong return signal is not achieved (this can happen if fishing over a very soft bottom or when trying to activate the zoom out of the water) the unit will not go into the Zoom mode. If the unit will not go into zoom mode, turn the GAIN up to 10, this will make the bottom signal very strong. Once the ZOOM has been activated, turn the GAIN back down to a normal operating level.

Signal Interpretation

Hard-bottom readings (rock or gravel) will be displayed by a wide band of RED light indicating a strong return signal. Conversely, a soft bottom (mud or silt) will return a weaker signal and will result in a narrower RED band or possibly even a combined RED and GREEN band. A soft bottom with weed growth will often appear as a narrow RED or GREEN band combined with both solid and broken YELLOW segments indicating weeds. Any fish in the weeds may show as RED or GREEN depending on fish size and relationship within the transmit beam (in the middle or on the outside of the transmit signal).

Reading Fish

Fish will generally appear as separate targets from the bottom. A fish target can be displayed as RED, ORANGE or GREEN, depending on the size of the fish and the location within the transmit beam. Larger fish located in the center of the beam (cone) can appear RED and will be displayed as a wider band on the display. Smaller fish or fish on the outside of the cone may appear ORANGE or even GREEN. Fish moving through the transmit beam may change color as the return signal strengthens or weakens reflecting their location. Fish that are right on the bottom can appear as part of the bottom. The best indication of a fish sitting right on the bottom is that the leading edge of the bottom return signal is either ORANGE or possibly a dithering or flickering RED segment. It is important that the GAIN or sensitivity be kept to a minimum when displaying a strong bottom return. Too much GAIN will flood out the ability to differentiate targets and clutter the display. Fish – Fish will generally appear as separate targets from the bottom. A fish target can be displayed as RED, YELLOW or GREEN, depending on the where the fish is located within the cone.

Reading Your Jig

The M1 will pick up and display small objects like jigs, spilt shot, or swivels. When tuning the unit to display your lure or bait, lower the object to the desired depth and turn up the GAIN until you see the jig on the display. It is important that the GAIN be set so it displays the jig as you raise or lower it. Sound waves emitted by the M1 bounce off targets and return with the strength of the targets’ density.
Denser targets return with a stronger signal, displayed as RED. Less-dense objects (small fish) return a medium-strength signal, displayed as GREEN. The least dense objects (weeds, bait-fish, lure) return a weak signal, displayed as YELLOW. Objects on the edge of the sound cone may appear as YELLOW. A fish moving through the cone may appear first as YELLOW then GREEN, then RED, depending on where the fish is located within the cone.
NOTE : Too much GAIN will cause clutter and may make it difficult to distinguish other targets like fish near the bottom. When tuning the unit to display lures or bait, make sure that the objects are in the center of the hole and therefore in the center of the transmit beam. If there’s water current (some lakes have underwater current or movement) and the lure doesn’t weigh much, it may move to the outer edge of the signal or out of the transmit beam altogether. This will make it difficult or impossible to pick it up on the display.

Dead Zone

All sonar units will have a dead zone in certain circumstances. This occurs on sharp drop-offs where the transmit beam (cone) hits the shallower edge of the drop-off and returns before the deeper edge returns. This in effect creates an un-displayed area between the shallower and deeper water within the transmit beam.
