Lowrance x27c

2 posts in this topic

Been having problems with this unit. It blanks out on the depth reading quite a bit, going both slow and fast. Going over 5mph it only gives me a light outline of the bottom. Ive replaced the unit and the transducer and its still bad. Is this a case of electrical interference? How can it be fixed? $1000 and it should give me the depth as I cruise the lake!!

Checking for electrical interference is always a good idea, try moving your transducer cable and your 27c's power cable to see if that cleans it up. Often you only need to move them an inch or two if electrical interference really is your problem.

Losing the depth reading frequently could also be a symptom of transducer mounting. How confident are you in your transducer location, the height and the angle. Try moving it if you can.

Regarding the light outline of the bottom over 5 mph, that could also be a symptom of your transducer mounting or interference. Otherwise, just make sure you have your ping speed and scroll speed set to high, and make sure your sensitivity is set on automatic or on a high setting if you're moving fast.

Good luck getting it worked out.

    • Thanks Rebel, very good answer.  I've been keeping track of the pressure for a week, now. 
    • Hey Rebel, what do you consider low and high pressure?  Perhaps a stupid question, but I just got a weather station so now I can start tracking barometric pressure. Right now the numbers don't mean much to me, been around 28-29% in the south metro the past few day and I don't know if that's low, high or middle.
    • Low pressure signals a front moving in, (Bad weather, wind may be  from the east or north) which usually puts them "on the feed", can have some hot and fast action. Likewise, a swing in the other direction, a high pressure system , (wind from the west or south) which signals clear skies and sunny weather, may do the same. The key to me, anyway, seems to be hitting it just as either front moves in. An extended low or long high may result in poor fishing. Remember the old adage, which also has to so with the pressure: "Wind from the east; fish bite the least...wind from the north , the fisherman goes not forth, wind from the south, blows the bait in the fish's mouth; wind from the west, is when the fishing is best". 
    • Those trumpers sure know how to keep things classy.
    • Is it true, the lower the pressure, the bite gets hot? Or the higher the barometric pressure the fish slow down on biting? 
    • Is that like saying "the lights are on, but nobodies  home.?
    • Newsie's where reporting on how the lights are on in the white house at 5am...   "First time in a long long time.."    
    • Beautiful!!! Can I ask what your dry brine for the side pork was?
    • Don't forget to get your Dihydrogen Monoxide detector as well!!! That's what we really need to be worried about!! Especially on and around lakes!
