On CLEARANCE DUE TO RETIREMENT, I have made and sold over 2000 of these in the last 8 years . It's been a pleasure, but it's that time!!! I am The REAL PORTAL! My boxes are the only ones featured on Ghost Adventures! Season 24 E 9, 31 minutes in. Also, in other episodes, my boxes are built, programmed, checked, and tested by me! When these are gone, I am done since I am retiring, and this is why the price is almost half then the others but still better quality than anyone else!!! my boxes are built, programmed, checked, and tested by me! I have the highest quality parts, and I am not here to make a fortune so there for I have the lowest price, so it is very affordable because times are rough right now! I also know my boxes are built, and work right is why I am the only one who takes returns. Other sights do not! You can use and will need either the SB7, (SB11 will need a separate cable) S-Box, and even phone apps! (You can use phone apps, but they are fake because they run off GPS). The size is 10L/5 W/6T. What you see in the picture is what you get. Why pay 300 to 400 hundred for a cheaper version of my item? What is a portal, you may ask? The Portal removes static & background noise from any spirit box or spirit box app (the user has the control to remove all of the noise or leave some static in if you feel as though it helps spirit communication). It also allows the user full control over how much reverb to add to the sound. We believe that reverb is key to not only clear spirit voices but also helps the spirits to manipulate. Easy to carry, Hear EVP's that you may have missed before without the Portal, that otherwise would have gone unheard or been unclear to hear. You can have full conversations with spirits if there are spirits around! You must have spirits around for this to work! When you buy one, you will receive a video from me on how to use your portal! It takes some time to practice, but the results are awesome! Just know there could be some paint flaws in the wood or paint. So please look at all the pictures so you know what you are getting! You will also be getting two battery packs, one venation cable, and one y cable! Thank you, and happy ghost hunting. Checked by professional ghosthunters and made with care.
