The Vonder rig makes use of a tripod and working table and is therefore more expensive than the conventional augering tools. However, use of the worktable and tripod ensure a straight borehole.三脚架钻井机使用三脚架和工作台，因此比传统的工具更贵，但同时也能保证垂直钻井。

Equipment is commercially produced by V设备由津巴布韦的V&W engineering in Zimbabwe. Local production is possible.W公司生产。也可以在当地生产。
