The steps to do this is quite extensive and I believe are best understood straight from the manual.
Here are links to the fisfinder 160 and 120 if you do not have them.

Hi,

If I may inquire, how many pins on the transducer and on the fishfinder.

Hope to hear from you and pls post back the requested information.

Good luck and kind regards. Thank you for using FixYa.

    The reason I asked was because the transducer intended for a 160 should fit the 120. To my knowledge the only difference would be that the capacity of the transducer of the 160 would be overly rated for the output of the 120.


    • A Garmin Fishfinder 120 uses a temperature-sensing 200-kHz transducer, which transmits at 800 watts (peak-to-peak) and 100 watts (RMS) to a maximum depth of 600 feet.

    • A Garmin Fishfinder 160 uses a temperature-sensing 200-kHz transducer, which transmits at 3200 watts (peak-to-peak) and 400 watts (RMS) to a maximum depth of 900 feet.
    Not unless there is a difference in the pin or the pinouts.

Is it posible to conect garmin 420s gpsmap to st40 deth transducer


No. St series from Raymarine are made for digital depth only, not fish finding and do not talk nmea. The only way to get that Garmin of yours to see depth would be to go from an ST40 nmea out to that garmin nmea in. Or purchase a nmea 0183 smart sensor and hook it to the garmin.

My Garmin depth finder/gps combo is giving me a false depth reading,like way way outta sack,not a foot or two. It came as an extra on a boat I purchased and elsewise seems ok,just inaccurate depth. Is it...


YOUR TRANSDUCER MAY BE SET FOR HORIZONTAL MODE...MEANING FROM BANK TO BOAT, NOT DEPTH...CHECK THE TRANSDUCER TO MAKE SURE, IT IS AIMING DOWN, NOT OUT...OTHERWISE YOU'LL NEED TO CHECK YOUR MODE SETTINGS IN YOUR MENU.

YOU CAN ALSO DO A TEST ON YOUR TRANSDUCER, BY SCREWING IT ONTO A BROOM STICK ...ADJUST THE TRANSDUCER DOWN, CHECK YOUR SETTINGS ON THE SCREEN, THEN DO A SIDE TEST WITH THE TRANSDUCER TILTED SIDEWAYS TOWARDS THE BANK AND CHECK YOUR SCREEN!

THEY CAN BE TRICKY...AND ARE VERY SENSITIVE, BUT ONCE YOU FIGURE OUT, HOW YOU WANT TO USE IT, YOU'LL LOVE IT!

HOPE THIS HELPS!

I think the transducer is down too low. Raise it up so that the center of it is in line with the bottom of the boat.

Garmin Fishfinder 160 will not display bottom contours and does not display depth continuously.


Change your setting from saltwater to fresh water even if you fish in sea water,your transducer is a 00/200KHZ and not a 50/200KHZ.
Good luck

Installing an old used lowrance fish finder


I don't think your old fish finder is the LMS-332C GPS Receiver listed above in the description. You don't need the speed wheel for the fish finder to function just the transducer and transducer mount. You should mount that on the back of the boat towards the center but not too close to the motor and not too close to the side of the board. Don't let it hand below the level of the boat. That should keep it from getting hit by the trailer or dragging on the bottom. Try to make it as level as possible. The green and white wires may be for the speed wheel but i'd need a model number for clarification. Hope this helps.
