SDI Begins Validation Testing and Announces Three New Colors for the Byrna HD

Byrna HD Consumer Rollout to Commence at the Start of Speedweek at the Daytona 500 on February 9, 2019

Wakefield, Massachusetts - December 20, 2018 - Security Devices International Inc. (“SDI”) (CSE: SDZ) (OTCQB: SDEV), an emerging non-lethal technology company, has issued a progress update on the Byrna™ HD non-lethal personal security device development timeline and new 2019 commercial launch initiatives.

SDI has conducted development testing using 3D printed prototypes and recently began the process of validation testing of the Byrna HD using production parts. Development testing has led to modifications which will enhance the performance and life of the personal security device. Additionally, SDI has decided to offer the Byrna in three more colors: black, desert tan and camouflage in addition to the original safety orange.

The final phase of validation testing that commenced in December 2018 requires factory production parts and factory production models. Due to the upcoming holiday calendar, a key supplier advised the company that several custom part deliveries expected in December 2018 will not be available until January 2019, pushing back the final validation testing phase by several weeks.

The company is planning the commercial launch of the Byrna HD to coincide with the beginning of Speedweek in Daytona Beach, Florida under its previously announced partnership with Rick Ware Racing in the NASCAR Monster Energy Cup Series. Approximately 200,000 race fans are expected to attend Speedweek to experience the Super Bowl of stock car racing, the Daytona 500. SDI and Byrna will be sponsors of the #51 Rick Ware Racing Ford driven by Cody Ware. Attendees during Speedweek on February 9-17, 2019 will have a chance to meet with the driver, Cody Ware, and Team Owner, Rick Ware, and see the new paint scheme for the Byrna Ford. Special introductory pricing will be offered to race fans who purchase a Byrna HD at the SDI sponsored booth during Speedweek.

“We believe the completion of validation testing is paramount to our commercial rollout, ensuring top quality, performance and safety on a global scale,” stated Bryan Ganz, President of SDI. “Initial indications of interest are extremely encouraging. As we look into 2019, the formal launch of our Byrna HD will be at the Daytona 500 in February and we couldn’t be more thrilled to be working with the entire team at Rick Ware Racing. We expect to have a robust press release schedule in the new year as we will launch our new e-Commerce store and fulfill our 3,000-unit purchase order in South Africa,” concluded Ganz.

About the Byrna™ HD Personal Security Device
The Byrna™ HD is a disruptive new non-lethal device aimed at the home defense and personal security markets. Its small size (similar to popular lethal handguns on the market today), ease of obtaining, ease of carry, effectiveness in deterring or stopping an intruder and accessible price point (under $300) should be appealing to individuals who want protection, but either don't want the hassle of obtaining a gun license or don't want the risk of having a hand gun in their home, as well as to gun enthusiasts who appreciate a precision piece of equipment and want something in their collection that is both effective and non-lethal.

The Byrna™ HD comes with multiple easily reloadable magazines that can hold .68 caliber training rounds, impact rounds or highly effective payload rounds designed to burn an assailant’s eyes and respiratory system upon contact. It will also be able to hold inert rounds and impact rounds that can be used for training. Accurate up to 60 feet, the Byrna™ HD is fitted with a picatinny rail that allows owners to mount either a laser sight or flash light making it easy for novices to fire it accurately. The Byrna™ HD is ideal for today’s homeowners, boaters, truckers, outdoor enthusiasts and gun enthusiasts around the world. For more information on the Byrna™, please click here.

The Byrna HD is not a “firearm” under federal law and does not require a federal gun license. State laws and local ordinances may regulate its possession, use, and carry in certain localities. More information on these types of regulations will be available on our website before the launch.
