I have the set. For a poor like me that sits at the bench and shoots shit at known distances it's awesome. Gives me great environment data and with accurate rifle data entered my solutions are always good enough for plates out to 1000. Bushnell blue tooth has communicated without error to the Kestrel.
I bought mine piecemeal. Overstock Kestrel I had to pay to upgrade and a Conx out of the PX.
