Do I need a Tuner??

[nipper]

This was shot at 50 yards , 5 shot group with eley match, was wondering if i needed to spend money on a "tuner" or not?? Any advice help full....

From that picture, but that is only 5 shots, so no. run a full 40 shot target and report back.

5 shot groups

You need more than 1 5 shot group. 8 to 10 groups or as Blades said . you need as least 40 shots in a group to really test your tune. The other thing to consider, is the discipline you compete in. What are the rules about the use of tuners.
