This is the must have SB7 SPIRIT BOX for EVP Ghost Hunting. The SB7 is the most popular instrument for EVP research. This P-SB7 is the 7th Revision and latest SB7 Spirit Box version - released Feb 2024. Added for the Rev 7 are two great features. 1. The scanning frequenices are now scanning inbetween the frequenicies that the previous versions scanned - in an added frequency half step. This makes it easier for voices to carry through more clearly. 2. One added faster scanning speed at 50 ms. for a total of 8 scanning speeds. Lots of ppl can hear communication more clearly at the fastest scanning speeds. This legendary device has given ample proof that it can instantly transmit unexplained voices. These voices, referred to as EVPs (Electronic Voice Phenomena), typically express intelligence since they often call out things that identifies people present at the investigation or something that pertains to the investigation. Also, communications coming across typically co-relates to the known facts about that haunted site, such as specifics about the spirits there. The P-SB7 is the most famous tool for instant spirit communications since it has been the favorite on numerous Paranormal TV-Shows. The P-SB7 works by scanning the FM band and AM band along with a unique high frequency synthetic noise, a.k.a. white noise, where spirit voices seemingly are able to form words. The P-SB brand's FM band scans 320 FM frequencies, which is further than any other competing brand known on the market, from 76 MHz to 108 MHz. Also, unique for the P-SB brand is that the band sweep speed can be selected. As mentioned, you can choose from 8 different millisecond sweep speeds. One can also sweep forward or backwards. Improvements that were already made with the Rev 6 from the Rev 5 are kept of course. Those are other than the added FM frequencies that there is no Audio Alert for Temp Changes since it would interfer with EVP sessions and you would have to recalibrate the SB7T Rev 5 and start over when the alert went off. Now, on the Rev 7 (as well as the Rev 6) the screen shows the Temp Changes instead. You can toggle the screen between Ambient Temp or showing the Temp Changes in 0.1F or C along with Scanning Speed and Band Frequency. And there is no longer need to stop the scanning to change the volume. The built in speaker is better - louder and with improved tremble. Note: The included screwdriver kit with built-in mini flashlight is a complimentarhy promtional free little basic gift added from us at GhoSt Augustine. It's a fun little gift and is handy when it is time to change batteries in a device that requires screws to be removed to change the battery - like in the famous K2 Meter.
