I mentioned in a recent testimony about Back Packs. Here is a photo of this new amazing technology to reach the remotes areas with the gospel and training material. also on the chips is a complete community development program. The sd mini chip hold about 30 hours of video. The battery is the size of a Ipad and last for aprox. 3-4 hours. This particular pack is going to India in the Telegu language. The speaker has a head set and can be used for a P/A system for meetings as well.
