Benefits of a Spotter phone mount No Sticky Residue Just slide your phone in and mount your Spotter magnetically anywhere. It's just that simple. No need to stick a metal plate to the back of your phone, no need to deal with sticky residue and messing up your favorite case, no need to keep up with spare parts. Bulletproof Construction Moving parts wear out over time, so a Spotter has none. Our proprietary precision-fit hardware fits snuggly with our high strength, flexible plastic. You can feel the durability. You will only need to buy once (until you buy one for a friend). Holds Heavy Phones Spotters are designed to hold 5x the weight of the heaviest phones, even with their cases on. Two ultra-strong magnets on the back of every Spotter make sure your phone will be mounted securely to any ferrous metal surface. Try mounting a Spotter and feel it leap from your hand toward the squat rack. Secure and Low-Profile Spotters don't stick out too far from their mounting surfaces, making them a more secure mounting option that's less likely to get knocked off. Plus, it's inconspicuous. If you want to record your next lift without setting up a bulky tripod in everyone's way, Spotter is your solution. Slide, stick, record. Better. Every. Day.
