How many times do you reach into your golf bag during a round to find your rangefinder while you are using your pushcart? This attachment which is compatible with clicgear, rovic and speedcart, saves you from looking for your rangerfinder by providing a sturdy base on your pushcart if your rangefinder has magnets in it or a magnetic strap around it. It installs or is removed in seconds using the umbrella holder and is rubber coated to blend into the cart. Do you have a magnetic strap on your rangefinder or does your rangefinder come with built in magnets. No rangefinder, cart, etc included Not designed for use with cell phones
