To those out there with NASA marine instruments?

 I have just bought a yacht fitted with 2 separate NASA Target instruments ie Log and depth but no booklet on how to reset either of them so they can be up and running. (boat goes into the tide n a week s time...)

Both register a response with scrammbled figures hinting that the power is reaching them but despite spinning impellar no reading on log... So  how do I reset both the guages plse???

can anybody supply that info please.

Get in contact with NASA they will surely help. They make good quality and very low priced intruments (but very ugly) that are very reliable - much more so than the NAVMAN rubbish I have on board - which fail as soon as you look at them - however they are look nice even if they are rubbish. My wind speed said it was either 5 Kts or 18Kts irresepective of how windy it was. The wind direction lasted 13 months (one month out of warranty) and died, my repeaters (I strangely bought 2, never learn) died after 13 months as well - curious that. However my cheap a cheerful Clipper stuff is resilient, and indestructible as you will find you Nasa stuff will be once you've sorted it out!

BTW Random junk like this on the display usually means that either the transducers have failed, or more likely, that the connections (though I rather favout the spelling used by The Times connexions) are not up to much.

As a first step, disconnect the  leads to the instrument , cut the wires back to clean shiny new wire, clean up the contacts, re-connect, smother in silicon grease and you'll probably have resoived it

Don't understand why Nasa stuff is ugly ? Considering that it's similar square design to many other company's gear ? One ugly = all ugly !!

I had Nasa on previous boats, fine. I have Echopilot Dual on present boat ... apart from logo / name on it / case colour it's near same design as Nasa Dual. Similar price, similar operation and results.

Don't knock NASA instruments. We had an echosounder which we think was about 24 years old and eventually packed up. Off to the local chandlery and for about 80 quid we bought brand new off the shelf, it still had exactly the same fitting holes as the old one and just plugged in to the old transducer.

All fitted and working in about 10 minutes and ready for another 20 odd years.

We've had most makes over the years which have given nothing but trouble and seemed to be obsolete in no time.

Nasa E/S transducer is standard item that fits near all other equipment that uses same freq. OK one or two have slightly smaller diam. transducer, but it's same detector embedded into the resin and plug / cable same.
