Every semester of every year you can read hundreds of reports where a woman was physically assaulted on campus.  While colleges and universities have tried to step up security patrols, especially at night, reports of attacks and attempted rape continue to persist.  While there are precautions a woman can take to lessen the chances of becoming a victim, one of the best weapons she can have at her disposal when confronted in a threatening situation is a shot of pepper spray. A less than $20, the MACE Keyguard Pepper Spray is compact, convenient, and has a key ring that easily attaches to your house, dorm room, car, and other keys you carry.  Be alert, be cautious, and be prepared. http://www.thecoverteye.com/preview/m7/80365--mace-key-guard-pepper-spray.html     http://www.athensohiotoday.com/news/woman-uses-pepper-spray-to-allegedly-fight-off-attacker/article_00fc4e80-8d84-55d7-a989-90264ed2f3be.html    

  Delta S Counter-Surveillance Sweeping System   Both Easy to learn and powerful the Delta S is a  sweeping system that quickly and reliably detects all types of RF surveillance device up to 6GHz.  The spectral analysis provides high sensitivity and a long detection distance of more then 10 to 20 times that of other RF detectors and near-field receivers. Plus the Delta S has a special mode to detect cellular  jamming devices. Quickly and reliably detects all types of RF surveillance devices in the range up to 6 GHz, including analog, digital, working continuously and periodically, transmitting audio or video, with or without encryption   Finds and identifies covert surveillance devices which use the digital standards GSM, 3G, 4G / LTE, 5G, Bluetooth, Wi-Fi, DECT and others in the range up to 6 GHz   Analyzes Wi-Fi 2.4 GHz, Wi-Fi 5 GHz, Bluetooth, “Bluetooth LE” and “Bluetooth LE Advertising” channels   The background masking feature allows you to reject friendly signals such as television, radio, mobile base stations, etc., and focus on finding local signals that pose a danger   Can be quickly adjusted to the local frequency allocation in the country of use (mobile and wireless bands)   High-speed spectrum updating and wide real-time bandwidth (RTBW) provide the ability to register short-burst signals   Search modes include: "All Signals", "Mobile/GPS trackers", "Wireless/ISM" and "Custom", as well as two additional modes for the inspection of suspicious bands or signals   Two antenna inputs and built-in antenna switch provide maximum sensitivity over the entire frequency range   Unlimited number of logs, each can contain an unlimited history of events   Unlimited number of logs, each can contain an unlimited history of events   The audio alarm warns the user about the presence of danger with a sound of variable intensity   The attenuator simplifies location of powerful transmitters   The "Hold maximum danger" feature automatically displays the most dangerous band or signal   Demodulation of audio in AM/FM mode   Works with, and is powered by, a laptop or tablet (not included)   Has convenient magnetic system for attaching the laptop / tablet to the main unit   Specifications: Frequency range 57-6000 MHz Sweeping speed 8 GHz per second ADC resolution 12 bit Sensitivity -85 dB Dynamic range 80 dB (with attenuator) Displayed signal level -90…-10 dB Real-time bandwidth (RTBW) 27 MHz Format Handheld unit Platform SDR by Analog Device Antenna inputs INPUT 1 – SMA, 57-2000 MHz INPUT 2 – SMA, 2000-6000 MHz Searching modes and time of update • All signals (~0.8 s) • Mobile/GPS trackers (~0.2 s) • Wireless/ISM (~0.3 s) • Inspect band/signal (~0.1-0.2 s) Visual elements (panels) • Level • Spectrum + Waterfall • Alarms Demodulation AM and FM with bandwidth 5, 15, 30, 100 and 200 kHz (in the range 70-6000 MHz) Requirements for laptop / tablet Intel Core і3 / AMD Ryzen 3 or better (recommended Intel Core i5 / AMD Ryzen 5) 2 USB ports, one should be of SuperSpeed type (USB 3.0/3.1/3.2 or USB Type C) RAM 8 Gb or more SSD 128 Gb or more Windows 8,10,11.
