Using this shooting target is easy. Just set it up in an outdoor area as it's recommended for outdoor use. When you shoot at it, the target will give you instant feedback on where your rounds hit the vital organs. Notice the different colored organs to easily see your round placement. As for maintenance, since the gel is water - soluble, if it gets on your clothes, it won't stain. Just clean the target gently if it gets dirty. Be aware that it's designed for most calibers, but always follow safety rules when using any shooting equipment. Keep it in a dry place when not in use to ensure its long - term performance.
