The folks at Garmin have decidedly figured out how to make the perfect Golf GPS.  The Approach G5 allows you to quickly measure exact yardage from any spot on thousands of pre-loaded courses.  Features include easy pin movement, waterproof touchscreen, and most importantly automatic yardage to all bunkers.  The video advertisement for the Approach even shows a golfer throwing the item on the ground to showcase ruggedness.  Nothing wrong with having all the knowledge at your fingertips before making that shot around the dog-leg.  $450 BUY
