If you have one, it would be great to find out what are the important specs for such a device. They are on ebay starting at suspiciously cheap $50. I figure on recording for example start up voltage transients in the vicinity of the starter, alternator and regulator. Using such a device, the intention is to eliminate a lot of theorising . The manufacturer tells me there is no history of this kind of trouble, and if there is a rogue regulator or capacitor this could be a definitive way to diagnose.

Been looking around and am interested in the Nav Data headset ( www.navdatakneeboard.com/index.html ). ANR is not necessary, as I'll modify my headset to ANR if I feel I need it (Headsets Inc.). So these seem like a pretty good choice. The price is right, and judging by the information, they are a US company (Florida). They are being sold at ACS, Tropicaero, The Pilot shop and several other pilot supply stores. But I can't find any reviews on them. Has anyone any experience with them? Or know anyone who has? Or opinions? Harley Dixon Long EZ N28EZ Canandaigua, NY ________________________________ Message 4 _____________________________________ Time: 06:53:38 AM PST US From: Subject: Re: AeroElectric-List: Nav Data Headsets Harley, At that price, I would be shocked if they were American made or of good quality. All of the headsets in that price range seem to fall apart in a few years with moderate use. I'd recommend a David Clark 13.4. You can add ANR later, and those headsets are absurdly sturdy. Of the five headsets I have, two are David Clarks, they have more use than the other three headsets I have but the DCs are the only ones that have never broken. My Lightspeed 15K has been sent to Lightspeed several times and now they no longer make several of the replacement parts, so next time it breaks I guess it goes in the trash. If a David Clark headset does break you can send it to them and they'll often fix it free of charge. On Ebay, nearly new 13.4s go for less than $200. New they are less than $300. My guess is that the NavData headset is just a re-badged cheap headset from a foreign manufacturer. It looks identical to the "SHS880C", the weight and noise reduction are identical to the 10th of an ounce. I think the SHS is Korean made. http://www.sadoun.com/Sat/Products/Aviation/SHS880C-Aviation-HeadSet.htm My opinion...the cheap headset will cost you more than a sturdy David Clark...and you have to deal with the inconvenience of it breaking when you need it.

I wonder if we took a survey, how many of those people now have hearing loss? $300 spent so that I can still hear when I get to retirement age seems like a pretty good investment to me. I can wear the $100 headset I have for about a half an hour before I start getting a headache. I have worn my Bose headset for over 8 hours in a day (two 4 hour flights, back to back with a small break in between), and at the end of the day I still barely noticed it was there. I consider the $950 Bose headset one of the best values I've made in aviation purchases. I've been using them for about 8 years now, so that's roughly $118 per year at present, with the cost decreasing and the value received increasing every day. -Dj -- Dj Merrill - N1JOV Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Glastar Flyer N866RH - http://deej.net/glastar/ ________________________________ Message 9 _____________________________________ Time: 11:15:29 AM PST US From: BobsV35B@aol.com Subject: Re: AeroElectric-List: Nav Data Headsets Good Afternoon Dj, I am afraid I am one of those who flew for well over fifty years without using any ear protection. I DO now have a considerable hearing loss. About fifteen years ago, I bought Bose Headsets for my airplane. Just wish I had started sooner! Not only are my ears protected, I now comfortably communicate with my passengers. Something that could only be done by shouting in years past. A good set of noise canceling headsets is the cheapest, lightest, and most efficient way to get a comfortable environment in any airplane. It beats thick windshields and massive insulation. As you said. The noise canceling headsets are not expensive, they are cheap when compared to other methods of sound attenuation. Happy Skies, Old Bob In a message dated 6/23/2011 12:48:40 P.M.

If you order the Rigol from tequipment.net, it will ship directly from China, like mine did. Rigol is a Chinese company, and makes decent products for people on a tight budget. The only issue I had was the foreign power plug that came with it. I substituted a spare US IEC cable (a computer power cord) and was up and going quickly. The DSO (which I've never used) may be made in China, but Sparkfun is in Boulder, CO -- to the best of my knowledge everything they sell ships from there. Both sparkfun and tequipment.net are companies I've bought from in the past.

Flying was one of the few pleasurable things we could do while waiting for the next set of orders to proceed to the nearest flight across the Pacific. Only benefit is VA providing the hearing aids gratis.
