A very useful tool for the elderly or anyone else who has difficulty bending over is a "Bowls and Jack" lifter. The use is self-explanatory but there are two different versions; a collapsible lifter or a 3 part lifter that screws together requiring simple assembly.

The lifter has two parts to the lifting piece - there is a smaller hole nearer the handle for lifting Jacks and smaller bowls (such as carpet bowls) and the outer part for lifting normal bowls.
