so today I went to harbor freight and got this Wolo powerhouse air horn for 50, ok deal I thought. And this horn is loud! lol but not as loud as the 300 dollar train horn set ups. I just wanted to share this sound clip.

And also if I have a 3 gallon air tank and set it at 25psi to run the horn off of, how long do you think that it would last bc I dont want to buy a commpresser?
