Two feet high.. is way too close to the ground..... However, if the beam is 10 foot high.. or maybe 15... that would be so much better and more accurate.. Expect some change when it gets top of tower.. but at 15 ft.. adjustments can me made reliable, with little change seen. Good Luck, be careful, ladders are more dangerous than towers,
