I do just about the opposite most of the time. I take my spiderlift to every job to get everything on the ground. We have a few certified arborists on staff, but with the spiderlift we can run circles around climbing technique most of the time. I still send them up trees(only because I have only one aerial lift) when we are working numerous trees in one yard. All my competition bidding on those tight spot jobs telling the customer "the only way to do this job is with a climber". Until I show them how we operate a bit different than the rest, and safer too. This will usually place more confidence in safety, giving us the go ahead to start the job. I am getting another bucket truck shortly, for front yard work and greater chip capacity, and this will even more diminish the need to climb. Climbing is sometimes unecessary when you have the right equipment. Climbing also wears out your body. I know of many of the climbers whom have worked for me in the past that have had both hips replaced(footlocker), knees blown out, shoulder dislocations, arthritis, etc. Climb for 30 yrs straight 5 days a week and you will start to believe that technology is the better route if applicable to the situation.
You care about a trees health, but what about your health?
