Just want to give a big shout out and thanks to Jack and the team at PRO. I just picked up my new Atlas Arm and gen4 battery base to complete my running rig today and again was completely blown away at the support from them. I have had my PRO for 3 1/2yrs now and couldn't be happier with my choice to go with them for my rig. There customer service and product quality is unlike anything I have ever experienced. Thanks again guys!
