P-SB11 Spirit Box 

The SB11 scans both the AM and FM bands simultaneously so that you cover the most amount of frequencies and optimize the chance of receiving EVPs. It  has many nifty features like giving you 7 different sweep speed choices and built in ATDD – Automatic Temperature Deviation Detection. So if the temp changes by 5F visual and audio alerts are triggered.  You can scan each band by itself if you prefer. The SB11 has been used consistently on paranormal TV shows and investigations to capture remarkable EVPs that relate to the investigated site.

How Does it Work?

The white noise of the SB11 and the fast scanning of radio frequencies is believed to provide the energy and transmission spirits need to get their voices through. The SB11 also features Temperature Detection Deviation to - or + 5 degrees F. Sudden drops in temperature indicate simultaneous paranormal activity. The red flashlight makes the P-SB11 Spirit Box night vision friendly and has minimum interference with capturing video and photos during your paranormal investigation.

How to Use

When using the P-SB11, you can choose between AM or FM, or run both at the same time in either forward or reverse while choosing the rate of sweep. It also has Dual Simultaneous Audio Outputs for simultaneous dual sweeps in either FM or AM. There are 2 Audio Output jacks, one for AM and one for FM. Running AM and FM at the same time creates clearer EVP transmissions. Turning off the antennae reduces the pick up of radio stations. Don’t forget your Voice Recorder so that you can listen to what you captured later!

  • Adjustable Sweep Rate - 7 different speeds from 50 millisecond to 350 millisecond

You get the clearest EVPs by using this configuration: SB11 through an ANC-Mini that is then connected to a Portal. The ANC-Mini has one Audio Input Channel. When using an SB11, if you want to use both AM and FM channels simultaneously, you have to add a small mixer in between the SB11 and the ANC-Mini, such as for example the Maker Hart JUST Mixer S.

Sp11 box’s spirit very good well

Well made bit hard on batteries could do with 9v power unit but works really well.been doing this kind of work for over 20

The Underpresence

Without a doubt, the single most effective EVP tool we have ever seen or witnessed. We routinely get INTELLIGENT responses to many of our questions using the radio waves the SB11 sweeps and the energy fields it produces. We've tried to debunk our results, but we simply cannot discount them. They're too accurate, and it would be nearly impossible (and illegal) to reproduce AM or FM transmission scanned at 150 milliseconds. This thing is AMAZING. Very durable, has survived a few gnarly drops. One single 9V battery lasts at least 4-6 hours in our experience, but maybe more. We change them with every investigation. Have not had an energy drain on our SB11 because we believe spirits like them! Hear our results for yourself. and buy TWO of these devices because they are that good.

I received product fast and as described!! I've only been able to try my new SB11 on one investigation. One thing I can say is the speakers are adequate enough to not need additional speakers ..which was nice!! I was pleased with how easy the unit was to use. I will definitely buy from you again! Thank you Ghost Hunters Store for a great experience!
