Caldwell Chronograph: This a current event. Ordered a Deluxe unit from Optics Planet. That was the very first mistake. Second the device would not work on my phone. No connection despite being sent two extra cords. Calling Caldwell customer service. The second mistake. Finally, got an exchange from the vendor. Got a RCBS scales that work great. I miss my Chrony that took a round. Looks like Chrony may be out of business. No more Midway, Caldwell or Franklin products for me. YMMV
