I have 3 of these bird launchers I bought from a lady whose father owned them prior to his death. When I received the units they were still new in the box, but probably a handful of years old. The issue I am having is the launchers are only launching pigeons 2-3, maybe 4 feet in the air. I called DT Systems and spoke to a lady in Customer Service and she told me they should be launching the birds 10-12 feet in the air. I asked her if there was any way to adjust the unit and she said no, that I would have to send the unit it on my dime, and then pay their team an hourly rate to look at the unit. Does anyone have any experience with this type of issue?
