Heres 2 pictures of my merlin with the micro trak pak and micro transmitter! She flies without hinderance and catches game nearly every outing. No signs of abrasion. She hasn't once picked at it. We followed marshalls instructions on how to fit it and used their recommended drug for the procedure, all went smooth and as planned. As you'll notice in the pics, it is uaually hidden from view but can be seen here. The antenna is usually all you can see.
