Many users find the convenience of wearing CORE on the arm strap over being worn on the chest an acceptable trade off for comfort over decreased accuracy.
NOTE:When CORE is worn on the arm accuracy is decreased. This is due to the thermo-regulations differences between the chest and upper arm.
The CORE arm strap is made of a soft durable material suitable to be worn in harsh conditions such as sport and still comfortable enough to be worn all day. The simple Velcro adjustment system allows for the one size to fit most.
