I thought I'd Share a very lame response from Lowrance.
See following correspondence from Lowance. I have since bought a Garmin fishfinder mounted in the same place that tracks bottom at 30 plus MPH and 360' of water. I would never waste my money on Lowrance again. BTW the response from Lowrance took about three weeks which to me is also unacceptable.
I said to Lowrance:
Last year I bought a Lowrance X58DF Fish-Finder for better than $200.00 Right now I am looking at buying another fish-finder. I always thought that Lowrance was one of the top line for marine electronics. I am not even considering Lawrance this time around. I don't think I have ever been more dissatisfied in a product in my 55 yr. The finder will not hold bottom past about 100 ft and sometimes less in the saltwater of Puget Sound. We typically cruise around 18 MPH and I have perforated my transom with far to many holes trying to make it work better. I finally epoxied it inside the hull and it looses bottom the same way. With the price of fuel like it is this season I am cruising more at 8knots and I loose bottom at about 150 ft. There is nothing worse than coming up on a narrow channel and not knowing what the depth is. If it doesn't come back on it's own I have to come to about a stop before it will pick up bottom again.
Lowrance Responded Three Weeks Later:
Thank you for your inquiry. There are many different factors that can result in poor sonar. First check your transducer to make sure it is still intact, parallel to the bottom, and not scratched up or dirty. Check the plug for oxidation and check the cable to make sure it is not pinched or crimped. Make sure no other electronics are turned on and run the sonar unit by itself. Shut the main engine and trolling motor off so there is nothing that can interfere with the sonar.
This is the best way to troubleshoot to see if the problem is in the unit, transducer, or caused from an outside source. Be aware that stained water and water turbulence caused from boat movement, windy conditions or currents can also cause erratic results. If the problem persists you can try connecting the head unit to another Eagle or Lowrance transducer to determine the cause of your problem.
If we may be of further assistance, please feel free to contact us.
