After being inspired by Kantis Nolef with his range finder I decided to do the same thing here is his original design
so here is what I am starting with
the actual unit
the ear cap removed (what a pain in the a$$ to take off BTW)
and starting the trimming of the ear cap
the actual pad will strap to the inside of my left arm.
I will post more pics as I go I would love to hear every body's opinion. and suggestions.
