A majority of phones now are waterproof or water resistant. That doesn’t do you much good if your phone is sitting at the bottom of the lake or river.
The Hawk Phone Grip is a great stand alone tether to slip in to your phone case and keep your phone secure. Clip it onto a float or a belt loop to secure your phone or add it to an existing leash. The Phone Hawk’s unique design allows you to place the tether through any opening in your phone case. Don’t be on the water without it.
