Low compression golf balls are ideal for seniors, as this type of balls tend to add distance to most player's shots. The Srixon Z-Star and the Wilson Staff FG Tour are two good examples, but most manufacturers produce a lower compression option.
When shopping for golf balls, the compression rating should be checked. Ideally, seniors looking for more distance should purchase balls with a 70 or 80 compression rating. As golfers get older, their swing speeds tend to decrease. Lower compression balls help make the best use of all the power generated in the swing, even it if it's not as fast as it once was. The only drawback is that there is a trade-off in terms of ball control when opting for lower compression balls.
