You have a starter putter ..... you are in a Country Club, so you can have the use of shot-pal and putter-pal. Both very useful to you.
The putter pal for instance has this:
10 lines dividing the length of your power meter. 1st line is 10% power the 2nd line is 20% of power, the 3rd line is 30% of power, the 4th line is 40% of power and so it goes on to 9th line being 90% power.
Your starter putter has increments (or scales) of 30-60-150 and 300.
If you use the 30 scale (your lowest on that putter) and you hit the 1st line =10% of power your putt will travel 3 feet. Hit the 2nd line which is 20% power your putt will travel 6 feet and so it goes on to 9th line 90% power when if you hit that your putt will travel 27 feet.
Obviously if you use the 60 scale then 1st line will go 6 feet, 2nd line 12 feet and so on.
The trouble is that long gap between 30 60 150 and 300 on that putter.
As you have said what meter increment do you want?
Different putters have different scales (meter increments) as was said.
Yes some have (A)10-20-40-60-80-100 others have (B) 15-30-50-100.
It is all about those lines on the putter pal divided into ten increments or percentage of power you want to hit.
Look at like this....putter A at the 10 scale will go only 1 foot by hitting 1st line ...putter B with the 15 scale will go 18 inches by hitting the 1st line whereas your putter goes 3 feet by hitting the 1st line.
All depends on what you need, but for me putters A and B will be much more accurate with their versatile scales to choose from.
Hope that helps.
