Depth Finder Doesn't Work- New Information
A couple of things frank:
- datamarine may be out of business, but there are two companies that sell parts. One is dmi marine at www.dmimarine.com - the other, I forget, but a google search should bring them up - I think they are both in the same town in Mass - Pocasset? - If you get a reading, it may be that something is interfering with the transducer - It should not have any anti-fouling paint on it. There should also be nothing else like say part of the hull or engine that could cause an echo - the beam has quite a wide angle - forget the number but probably about 30 degrees. - Stupid questions, but do you have more than 2.1 ft below the transducer when docked! BTW, don't worry about pulling the transducer (if it is of the retractable type). It would be best to have a plug that you can use to stop the water coming in - Most units were supplied with blank plugs when new, but a rag or tapered softwood plug would suffice for a short period. A spare set of hand s may help. Try cleaning the unit and dropping it over the side to see if you can get a different reading. BUT, I have a Datamarine depthsounder myself (different model), and the transducer cannot be pulled - It is permanently installed - If it is removable, there should be two nuts - one that holds the thruhull in an done at the top that holds the xducer into the thruhull. Finally - You can buy a complete new depthsounder with a transom mount for less than $169, so shop around! Good Luck! "frank1492" wrote in message ... If you have read all my messages, would you agree that the transducer itself is likely the cause of the problem? If something else is likely (or possible) I need to be careful because the transducer will cost about $170. Are you saying that when I pull the transducer out, the hole will go all the way through? Seems pretty risky with the boat in the water. I assumed that it would be like a chamber with the bottom sealed off so that I would just drop the transducer in with no "fountain." Thank you very much for your help!! Frank |
