Lowrance x27c

[O2Fish]

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.
