Went out about 30 miles yesterday and on the way in my Lowerence depth/fish finder (basic model) started reading crazy numbers then nothing but 00, the water temp still shows up, menu, lights, but no depth, any ideas before I buy a new one. Thanks Deano
 
Is it a through the hull transducer or one that sits inside the hull? Check all the wiring and you might try power cycling the main power feed. If it shoots through the hull (doubtful) make sure it is still in the proper position. Also excessive growth on a through hull transducer can cause false or bad readings.

Transom mount units can get "kicked up", or detached. If transom mount, check for proper orientation.

That too, I forgot about transom mounted units Bill.

And if it is a transom mount T/D but it's still intact and down in proper position with no fouling caught or growing on it, try switching from auto range to manual and set it to include at least the present depth to see if it will lock back on. And use manual gain to optimize that setting to just remove excess noise.

But if your T/D experienced a hard-debris strike or is leaking it could be kaputsky.
 
Still, you can probably order a new transducer for less than a new unit.

Turbulence from a dirty bottom can make 'em read crazy too. Does it work when you're stopped?
 
Hi, it is a transom mount, and yesterday I cleaned it all off and pointed it in both a horizontal and down position. and it still blinks 00 both docked and under way. really hate to go through replacing it if can be fixed. It always worked great until Saturday. Is sender supposed to point down ??

Thanks Deano
 
The flat part of the transducer points down. I think I'd find the manufacturers phone # or web site and talk to them. I would guess transducer or cable, but talk to them first. You don't want to replace the transducer and then find the problem is in the display.

Speaking of cable, have you checked the plug at the back of the unit?
