have been using one of these for two golf seasons.THE VERY FIRST TIME I USED IT OUR GROUP WAS STARTING ON A PAR 5 HOLE. TRIED TO RANGE THE HOLE BUT THOUGHT NO WAY WILL I GET THE PIN. WRONG, VIBRATED ON THE PIN 484 YARDS. WOW! WORKS GREAT DOES SEEM TO RANGE 2-3 YARDS MORE THAN TRUE YARDAGE BUT I'M NOT THAT ACURATE ANYWAY.
