About the HGpeN

This video demonstrates the use of the HGpeN Horizontal Gaze Nystagmus tool.

The HGpeN was designed, developed and patented with input from SFST / DRE law enforcement professionals, prosecutors and defense attorneys. After several years of research & development followed up with intensive field testing, we have a product for the law enforcement officer that is not only simple to use, but reliable.

Beautifully designed, user friendly, easy to use, and simplifies a common task. I think the benefits are limitless. I recently compared the HGPEN to the biggest advance in technology in Law Enforcement since the Taser X26.

I think 2 or 3 years from now the HGPEN will be a standard piece of equipment on a patrol officer’s uniform. Imagine sitting on the stand at a jury trial and being asked how long you need to hold the stimuli at maximum deviation, except you know the answer and you nail it. It feels good until the Defense plays the video tape and it shows that you only held it at maximum deviation for 2 seconds, but you just said you held it for 4 seconds.

The biggest benefit is simply not getting embarrassed during a jury trial by the defense attorney. It is a horrible feeling to be sitting on the stand for a jury trial and not know the answer to a question or be backed into a corner. What price do you pay to not experience that? I just paid $59.95 and it is well worth it.

The purpose of the HGpeN is to provide a standardized instrument to Law Enforcement for the HGN test battery. NHTSA has stated “Officers do not have standardized instruments with which to make precise measurements in the field”. The HGpeN solves that problem by implementing patented technology based on NHTSA guidelines that takes the guesswork out of properly administering the HGN test battery.

In 2012, there were 1,171,935 people arrested in the US for DWI/DUI. According to NHTSA, there were 10,322 drunk driving fatalities in 2012-compared to 9,865 in 2011. Providing law enforcement with the tools they need to accurately identify intoxicated/impaired drivers is a top priority for MADD and NHTSA. The HGpeN improves officer testing, assists in accurately identifying intoxicated drivers, improves courtroom testimony/convictions and also reduces overtime costs; but most importantly, it can help save lives.


We are proud the HGpeN is assembled in the USA and compliant with “Buy American Provisions/Recovery and Reinvestment Act” provisions.

At HGpeN, quality is not only a mindset, but also a way of life. We employ strict procedures and maintain control of quality throughout every step of the process. We employ a three-stage system to ensure quality control is applied in each stage of our operation.

Stage one of the process is to inspect all incoming components prior to assembly.

Stage two governs quality during the assembly process to detect any problems that may arise as a result of assembly. At this stage we perform inspections on assembled and in-process assembled units.

Stage three is our Outgoing Quality Assurance. This is the final process before products ship to customers. Specific tasks include: Perform visual and functional inspection of each HGpeN and if any issues are discovered, submit failure analysis reports and alert vendors.

At HGpeN, we strive to provide law enforcement with customer service that is second to none.
