Ghost Voice 2 (ver 1) has all the same features as the original Ghost voice did have. The frequency range is 1mhz thru 150mhz, while the user can still select the low and high ends down to 10 different frequencies to scan from. For example you can select 40-41mhz, even though its technically one frequency range, remember the GV2 will still scan the tenth range giving it still 10 different frequencies to scan from. Example: 41mhz, 41.10mhz, 41.20mhz,41.30mhz, 41.40mhz, 41.50mhz, 41.60mhz, 41.70mhz, 41.80mhz, 41.90mhz, and 42mhz will all still be scanned.
 
Soft mute -  This function mutes the gv while it scans thru frequencies, and when a sound comes thru it UN-mutes so user can hear the sound (voices and other sounds). This typically cuts a lot of static and noise out of the scan.
 
Sweep directions:  Forward, Reverse or Random

Two radio modes:  Auto scans the band (AM/FM) that is chosen.  Manual scan has the ability to just sit on one frequency and the user can select when to move it to the next frequency

Frequency Ranges can be manually set to ranges between 1 to 150.

Detuned Option - DEtuned means the GV will deliberately not entirely tune to frequencies.
 
Ghost Voice 1's description:  Ghost Voice Frequency Scanner has an impressive range of 1hz thru 150hz. This ghost box has linear sweep (forward & backward) and it has random sweep. Users set the range from 1hz to 150hz. Set as many frequencies you want to scan. The unit will scan in increments of .1hz at a time so if you have 1hz of frequency to scan, it will still run thru the 10ths of that frequency.
 
We didn't stop there, we also included a 3 watt power woofer speaker along with a 3 watt power amplifier. We included an audio mute button so you can press on it to shut the internal speaker off while asking questions, again, if your recording audio, the audio port will still record voices that may come over the frequencies even if you have the audio mute pressed. We put a antenna jack on this so you can completely remove the antenna to ensure no radio stations bleeding in occurs.    You can also use in the detuned mode and eliminate broadcast sources.
 
Ghost Voice has 6x sweep rates and one turbo mode so you can set the timing of the auto scanning on this or just simply set the unit to stay on one frequency during the session. The new Ghost Voice is completely rechargeable so no need to purchase batteries.
