    I have some of the same questions, so if any of you received responses on the battery or if it will work for ice fishing, please let me know. I also have a newer unit, that looks similiar, but is brown and the case is made out of plastic. It looks like it takes the same battery.

  11. STEVE says:

    I TO HAVE COME IN POSSESION OF A LOWERANCE FISH LO-K-TOR LFP-300D, AND I ALSO DO NOT WHAT TYPE OF BATTERY IT TAKES . CAN YOU HELP ME ?
    THANKS STEVE

  12. allen says:

    I have got this leather green box that says fish lo-k-tor on it. Someone gave it to me. It came with no instructions. So i don’t know what battery works it. The tag number on the box is 23885. Please send me some information on the lo-k-tor.
    Thank you,
    Allen

  13. Steve says:

    Any I dea where I can find a transducer?

  14. Andy says:

    Any 192 khz transducer will work. Go to Radio Shack and get a 1/4″ phone plug. Very simple to install. There are several transducers on ebay right now.

  15. dave says:

    The unit takes two 6 volt lantern batteries. I use the remington 6 volt re-chargables available at walmart for like $5.They are seal lead batteries so you don’t have to worry aout them leaking and they last for like 12 hours.They go in any way as long as the springs are facing the front of the unit.

  16. Anonymous says:

    I have the same unit and have used it since the 80s. Use good quality six volt square lantern batteries. Insert in the box with the springs toward the front.

  17. Mike says:

    I have a LFP-300 in mint condition and it works very well. Yes they work for ice fishing and you can even ping through some ice as long as the transducer is wet on the tip. We just drill a hole just big enough for the transducer and just hang it down. I have several manuals and even the sales broshure. Mine was made in 1965 and I think they were released in 1963. The tags that several people are mentioning are the original sales tags, keep them with the unit or at home in a safe place. Value? working units in good shape $20 – $60 depending on condition and manuals. But they work great and you should keep it and use it.

  18. Rick Miller says:

    Dear Debbie or Mike,
    Would there be a way that I could get a copy of the units manual. I’d pay the copy expense and shipping.
    I to have a little green box or Fish LO-K-TOR and would like to know more about it.
    Thank you,

    I have green box in working order with the transducer mount that I will sell it is in good working order. I used it for ice fishing in Michigan but have been in Alabama (not much ice) since 2004. I would like $50 for it

  20. Neal says:

    Andy,
    How do you know the Lowrance LFP 300D uses a 192 Khz transducer?….do you have a technical specification document?…just curious.
    Thanks,
    Neal

  21. Neal says:

    I just purchased a Lowrance LFP-300D and it has the original instructions, sales brochure, box and receipt $166 in year 1979.
    Indeed Andy’s note above is correct because the specifications show 192 Khz in the paperwork.
    Regards,
    Neal

  22. Rich Cochran says:

    Would anyone please email me a copy of the user manual for the LFP 300 FISH-LOK-TOR rchrd_cchrn@yahoo.com Thank you very much for tour assistance.

  23. Kevin Vervoort says:

    Did you ever get a response to your need of paperweork for your Fish Lok-A-Tor, if so could you please forward them to me also….. hoping to get this working, functions but doesn’t show fish…..just the bottom……thanks Kevin

  24. KevinVerVoort says:

    If anyone has paperwork on this unit please email me at kevin_26_99@yahoo.com, we can trade phone #’s ore I can give you my address to send paper copies….. anything to get the manual and such…..thanks

  25. Brenda says:

    Trying to find 6V batteries now is difficult – so here’s a tip I’ll share – Amazon sells floating lanterns for under $4 packaged with a battery – you will need 2. Walmart carries the lantern pack as well for over $7 each. 6V batteries are rarely used now so they are expensive to buy. This is the cheapest option I have found – lantern becomes disposable but for the price of what the 6volts are going for its the most cost effective. Good luck.

    Do you still want manual for green box. I have one and will send in mail. I enjoyed mine and hate to toss the booklet. douglaspfau@sbcglobal.net

  27. ken says:

    I purchased my green box in 1975 or 1976. It was readily available then at all tackle shops.
    I purchased a conversion kit and ran it off of a standard deep cycle battery most of the time.
    I found one at a Garage Sale in Mint condition two years ago. Never used! Got it for $10. I I still have my original green box and will display that one in my den. I’m tempted to use the new one.

  28. Anonymous says:

    hey people, all of you who are worried about batteries. the 6 volts are hooked up to produce 12 volts, so all you gotta do is buy a small motorcycle/atv/lawnmower battery for about 20 bucks, cut the wire leading to the battery area and splice in appropriate connectors for your motorcycle/atv/lawnmower battery. most batteries of this size use a slide on spade connector. takes 5 minutes and you can use a rechargeable 12 volt battery that will still fit inside the green box battery area. good luck. the red wire is positive and the black wire is negative, match those to the battery terminals and your in business. that buying lanterns for the 6 volt batteries online sounds like a horrible way to power a little green fishin box! 🙂

  29. Kent Kircher says:

    I have a LFP300 . It looks brand new and in the original box with
    the Operations Manual. The original cost was $179.95.

    I also just bought little green box and would like to find an owners manual. Can anyone tell me where to get one
    Randy

  32. Ben Ellison Ben Ellison says:

    Cool. Lowrance saw these comments and just sent over the original Fish Lo-K-Tor manual in PDF. See PS above for download. It’s a great read!

  33. That manual is not dated, but it contains a Zipcode, which dates it to 1963 or later.
    However, the Fish-Lo-K-Tor dates from September 1959, after development since summer 1957. See the history here:
    https://www.igfa.org/Museum/HOF-Lowrance.aspx
    That really is amazing; the transistor was brand new technology then. The transistor radio is only a few years older.
    Compare the photo in the IGFA article to the photo at the top of this post. I’m guessing here, but I’d say that happy fisherman is Darrell Lowrance himself.

  34. Randy says:

    Ben, not seeing the “PS” above. Can you elaborate? Thanks

  35. Ben Ellison Ben Ellison says:

    Randy, you may need to refresh your browser. It’s right under the photo of the Fish-Lo-K-Tor, link to PDF here:

    I have a LFP-300D green box lowrance fish lo k tor. Would like to know if it shows fish on the screen.Have no manuel for it.Seems like it only shows depth.

  37. Grayson says:

    Hey guys looking for somewhere i can get ahold of an old transducer for my green box…any ideas? Love the old unit please let me know. I would really like to use the unit again once it’s complete. I am literally dead in the water without it!
    Thanks

  38. gary says:

    do you have copy of lawrance lfp-300 manual

  39. Ben Ellison Ben Ellison says:

    Gary, the Fish Lo-K-Tor manual that’s linked to above and below does not mention model LFP-300 but a lot of readers seem to think that they are the same thing.

  40. Jim says:

    Hi, the wire that goes to the male plug broke off right where it is attached (screwed down) to the plug. I see there are two wire inside the main wire, which one should I re-attach ?

  41. f hribar says:

    I know this post is old, but I just rigged up for 12 volt (2-6es) by unsoldering two wires from battery board and adding wire to them and put on alligator clips for 12 volt.

  42. Paul beckm says:

    How do you install the batteries?

  43. Bill frovik says:

    Hello
    Does anyone have an schematic for the lpf 300. I’ve been looking for a long time and called many shops.
    Thanks for any help
    Bill

  44. Podge says:

    I know your post is from 2008 but did you ever get a reply on whether the transducer has to be in water for the light to work and show depth. Does it have to be in 4 feet or more of water.

  45. Ben Ellison Ben Ellison says:

    Podge, most any sonar transducer has to be in water to operate, preferably a few feet.

  46. Anonymous says:

    Ben do you happen to know if the strobe light on the unit will light up when you turn it on if the transducer is not in the water to give it a signal. When i put the batteries in and turned it on the strobe light in the dial spun around like it is suppose to and the battery indicator reads full charge but the light doesn’t light up. Do I need to take it to the lake and put the transducer in the water with at least five feet of depth from the transducer to the bottom of the lake? Thanks, Dave

  47. Anon, I would think it would NOT light up, as the flash is triggered by the echo from the bottom. Without an echo, no flash.

  49. shelly miller says:

    could you please email instructions i just bought a 300f fish finder no transducer but i will get one pd. 1.25 good buy hopeing it works

  50. Albert Franchetta says:

    I have an old Lowrance flasher unit. It is a series 2000-2160. Is there anywhere that I can get a power cord and transducer for it?

  51. Brian W. says:

    The light should light up at the zero foot indicator without a transducer plugged in. I use mine for ice fishing and it works great! If you have some clear ice, spill some water on it, plant your transducer on the wet area, it reads the depth right through the ice. I find the depth I want this way before I drill a hole. It also shows the fish coming and going. Will I buy a vexilar any time soon? NO I Won’t!

  52. Clint Bridges says:

    I have one and the circuit board inside is marked 505B and is dated 1961. I need to replace the capacitors on it and wonder if anyone else who has an older one would post the values for the capacitors on their circuit board her for me. I especially need to identity the one marked C9 on the circuit board.

    Thanks
