This invention relates to lance-type pressurized sprayers. In spraying methods using a single-nozzle pressurized lance, besides the problem of non-uniform spray, there are issues of operator contamination with chemicals and lack of proper working width adjustment. Although various handheld and backpack boom designs exist, current designs address spray uniformity but still allow operator contamination under certain conditions and do not provide full control over working width. Existing designs generally position the handle or boom attachment in the center, which only partially mitigates contamination. Even light wind can still expose the operator to chemicals. Moreover, current designs are suitable for some fields but not for others, requiring additional equipment. In this invention, a six-nozzle boom is designed with the capability to reposition the handle at different points and to adjust the angles of both the handle and the nozzles. The handle repositioning is necessary for the contamination issue. The boom allows working width adjustment for any number of nozzles, enabling the operator to easily adapt to a wide range of field conditions. The solution is delivered using a combined wet and dry transfer method, ensuring all functional advantages of the boom are achieved.
