After going without a chronograph for a while, I am planning on purchasing one to replace the Shooting Chrony Alpha Master I shot with my 35 Whelen. I have a gift certificate from Amazon that I would like to use so that limits me to what they offer. My preference would be to replace the one I have with the same model but, it seems, Shooting Chronys are hard to find and none are currently offered on Amazon. A quick check with shooting supply retailers show few models, if any, in stock and Midway indicates "no backorder" on their website. I wonder if they are going out of business. So, any suggestions for a suitable replacement are appreciated.
