Rugged Design Minimizes Shakiness When Filming Water Resistance Level : Water_Resistant The APEX Pro Motorsports Phone Mount was designed in-house by APEX Pro for the demands and rigors of motorsports activities. The strong suction base is rated for 5 pounds. Holding your phone securely is no problem! The sleek anodized aluminum phone holder is adjustable and can hold the largest smart phones currently available on the market. This mount is designed to shake less while filming than other phone mounts. Other phone mounts use magnets or insufficient clamps. We designed this mount to withstand abuse at high speeds and g-forces on the race track so filming backroad drives or holding your phone during your commute is no problem! In our testing we have found the iPhone 13, iPhone 12, and iPhone 6S to have the best stabilization for in-car filming. You can use the phone mount to film video and display lap times on your phone for a variety of motorsports applications like road racing, track days, drifting, autocross, rallycross, and hill climbs! This mount fits a variety of devices including phones from Apple, Samsung, Google, LG, Motorola, Sony, and more!
