20 Most Recent Navman Fish 4150sx GPS Receiver Questions & Answers

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.........

You can download the manual from the following location:

I have also sent you the e-mail with the manual.

This is my e-mail adress [email protected] send me your adres and I will send you the manuel

I had the same problem last time I was out in shallow water (in less than 2 metres of water) and I suspect that the problem was weed wrapped around the transducer but won't know for sure until I take it out on the water again. I had another problem re water temp which I'll enter separately.

Go to the Website of Pertec.co.za and download the manual for the 4150 and 4150sx
Hope this will help

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.

Go to the Navman web site and you will find your answer.

Not for that model. You can for others, you buy the UK map. I recommend the Garmin Drive 50 for the UK. I bought one for a friend in the UK and bought one for me here in Canada. https://www.navman.com.au/ezy15#Features https://www.navman.com.au/international-maps https://www.google.com/search?q=Australian+Navman+EZY15+UK+map ..
