SAS Tactical Survival Bow VS Primal Gear Unlimited Survival Bow
Here is a comparison video between the SAS and the PGU. Comparing the two bows in materials, arrow speed, poundage, penetration, decibels, special features, and comfort. This has been an interesting and long video of testing processes and research to insure and capture the differences and similarities. Both bow performed very well in the testing processes and are great tools. It really comes down to personal preference and special features when deciding which bow is better suited for your needs. Hope you enjoy the video, and please comment with any questions thank you.
