Yes not to far from where he lives is a large state forest. But it would be more fun to go with someone else. I can go by self if I need to. If I never meet him or talk to him, that would be fine. I think it would benefit both of us, if we worked together.

Still working the issue. From what I am finding most of the cost is two factors. Frequency response below 20HZ and small and light weight hand held size. The small and light weight factor and response below 20HZ are diametrically opposed design factors. The specs for the device list the microphone and preamp used in the device. The microphone is a condenser mike that has a 5 to 20,000 HZ frequency response. The preamp has the same 5 to 20,000 HZ specs. Quite frankly I would want something capable of detecting sound below 4 HZ since I detected that when I got zapped. The mike and preamp are available separately. As some of you may know a condenser mike takes various voltages up to 200V as a bias voltage since it functions as a condenser in a circuit that has a movable diaphragm next to a fixed one a few microns away. The microphone is less than 1/2 inch in diameter. A larger microphone or one that functions on pressure differential should be a lot cheaper. I have the feeling that a 15 inch disk of light gage aluminum sheet with an attached coil in a strong magnetic field would detect infrasound as well as any microphone that exists. It certainly would cost a fraction of the one I mentioned above. Whatever I make will not cost but a fraction of the one that was quoted. Rather than produce them I would just say how to make them with available materials.

Thanks for the clip, JKH! I've lived in the country most my life, slept with windows open, don't recall hearing the daytime crowd at night until recent years. Quite memorable when they do sing or call at night! (The calls/singing I heard did not sound like they were alarmed.)

Lots of Detail.

Thanks, Gigantor. I have no idea what's going on with their website. I'm n Thanks, Gigantor. I don't know what's going on with their website; I've never had any problem accessing their website the last few years. I'm not sure what it means to be completely down and no message with any explanation coming up instead. One of the few ways to find anything was through Facebook, though it doesn't give all the info. I do kind of like their logo. It would look good using any state. I did come across a website called "The Bigfoot Portal" that had a mention of this years OK Bigfoot Symposium but it only showed the dates and the location and no other info. It did have a page about last years OK Bigfoot Symposium and it showed one of the featured speakers in 2019 was an All Female Research Group called "Sisters of the Moon".

Driftless has some good stuff. He's one to watch. Just recently it appears that the sasquatch that he was having experiences with followed him home, and structures have begun to appear on his property. So, very recently, he chopped them down and made a fire out of them, LOL. I'm looking forward to seeing what happens next!

Another option might be to email Les Stroud and ask the question. I know I've seen $1000 somewhere, but I don't know what that included. It's funny you should bring this up because just the other day I saw something about eDNA samples done on bears in the Himilayas to determine species from tracks in snow. Apparently, they can get skin cells from the snow to extract the DNA. I thought of you for some reason when I saw that...

I would talk to your biologist friend then, Madison, especially for cost specifics. Your friend may also know of any citizen science programs being run by FS , F&W, or the universities. Your biologist may either already know, or want to know, why YOU want to know. Please post what you find out and whether or not you want some details about what's already in place as far as what someone might use to collect samples. There are products available for detecting the Human genome and other products that primate researchers use to detect other Great Apes. That alone may help in any dialogue you may be able to have. Read up on the "why we can't find and study Sasquatch" thread as there's a lot there in the last few pages that might help clarify things better for you. So between contacting your biologist friend and actually getting into a conversation you could have some time to get somewhat up to speed on the subject if you're not already. It would be beneficial for NorthWind to perhaps do the same? Good luck on any future meetings or talks you may be lucky enough to get into. I also would be more than happy to answer any questions that mey crop up

I wish I could say I spent lots of time researching and finding the best value I could, but the truth is that I found this in a rental car in Arkansas. I'm guessing whoever left it behind is not happy it's gone.

Well I received the quote and it is totally out of the question. Listed price with options is $12,750.00 I can likely engineer something on my own for far less than that. The problem with engineering my own gear is that I need to first produce infrasound to have a source to use to develop a recorder. That microphone might be a starting point. I really do not want to get into writing software again. Did that, had a business, and got taken to the cleaners by people stealing from me.
