Manual Could I get a hold of a Navman "Fishfinder" manual Please? fish finder in new boat purchased by me from new...no manual for navman fishfinder 4380.

• I would think not as the resistance and transponder are matched to the unit.

Here is the link to the owners manual.It has a copy of a wiring diagram.Not sure if it is the one you are looking for but maybe someone else may be able to use it if not. Hope this helps you with your project
Good Luck

Hope this is helpful and happy boating!

Took me a few minutes.. They make it hard.. But anything for a fellow fisherman...

Its available in many languages so im giving you the link to main fisherfinder downloads on navmans website. Open the link and scoll down to discontinued lines first choice is FISH 4200 and choose your language and it will open right up if you have adobe reader for pdf files. Its 32 pages long so its too much to put the manual here.. good luck!!!

I installed my Navman 4150 depth finder along with the Navman GPS unit when I purchased my Bayliner Trophy 20Ft. Offshore model. Everything was ok for one year and it has been downhill since then. Losing signal, unbelievable high depth ranges, blank periods, etc.. I now can't even get a reading tieded up at the dock. I am now giving up and shoping for a quality unit.. Cape Disappointment.........

I finally got an email reply from Navman. If the unit is less than two years old (mine is not) they will repair it. If it is over two years old, or if you can't prove that it is less than two years old, you can ship it to them and they will repair it for the low, low price of 355 US dollars.

Pretty nice of them since it appears these units are highly problematic isn't it? I am wondering if they guarantee their fix, or just have you on the hook for another 355 dollars later.

Good Luck Everyone,

Walt

hello :

sir Any series used
You can choose manual from here.

dont forget rating this post if this is not helping u tell me so i can help u further .

Depth: Could be for a number of reasons, too deep for the sounder - check the manual for it's max depth. Dirty water, sounder unable to penetrate through to the bottom. Weed or other debris covering the transducer. Transducer on a swing mount & being pushed out of alignment then dropping back in once stopped.

Speed: Is the speed readout controlled by a GPS or paddlewheel? If it's GPS, check the power connection of the sounder, may be loose which would also cause the depth to 'drop out'. If it's paddlewheel, you're down to bad connections or faulty unit.
