Is there a difference range golf balls and regulator golf balls?

Possibly. Many Golf clubs and driving ranges use "limited flight" balls. This requires less space for the actual range itself.

The "range ball" is designed in such a way (with shallower dimples) that prevents it from flying as far as a "standard" flight golf ball.

Range balls also typically have a harder cover, making the ball more durable (but less forgiving and further decreasing its flight).

Ask the pro at the club or an employee at the range, and they should be able to tell you what kind of ball is used (limited or regular flight).
