Hi everyone.
We, at the company, are evaluating to purchase an ELF arm for balloon data acquisition.
It is manufactured in Germany by Four Audio.
I would like to know if you have information on similar devices on the market.
Besides, as I will be visiting the US on November, I would like to know also the possibility of visiting a facility were an ELF or some other device like it is employed.
Any advice will be welcome.
Thank you.

I believe Danley has a device like that.

I believe Danley has a device like that.

I visited Danley several years ago, and this is an appreciation, but they didn't seem to have any measuring facilities at their Georgia location. This could have changed after my visit.
Pat Brown, on his Prosound Testing website, includes Danley on his measuring projects.
There they use a custom-made device for polars. Perhaps the ELF didn't even exist at the time?
The million dollar question is what would he employ today? A custom-made device or a finished product of recognized performance?
Cost and development time involved on the two alternatives are totally different.
Thank you Dave.

I recently saw a post showing Tom Danley using a new device, so things might have changed.

Thank you for the update Pascal. We know that measuring system since many years. It's an extraordinary tool but unfortunately extremely expensive for us.
