A gap wedge is usually lofted at 52 degrees, although can be some variation. Pitching wedges usually have a loft of about 48 degrees (although older pitching wedges sometimes have higher lofts), while sand wedges usually range from 55 to 58 degrees. This leaves a gap in loft that the gap wedge is designed to fill.
According to the survey, over 740 billion text messages were sent over carrier networks in the US during the first half of 2009. To put that astronomical number into perspective, it boils down to 4.1 billion SMS messages being sent daily, which is also nearly twice as many as sent during the same time period last year.
The number of texts being sent is on the rise, especially among teenagers age 13 to 17. According to Nielsen, the average teenager now sends 3,339 texts per month. There's more, though: teen females send an incredible 4,050 texts per month, while teen males send an average of 2,539 texts. Teens are sending 8% more texts than they were this time last year.
