I think you will enjoy it, chronos can be fun, and a good tool.
It looks like the Caldwell can be connected to a phone/device with a cable. It''s nice to be able to pull the data and save it for later.
My CE chrono spits the data out as a .csv that can be pulled into spreadsheets.
I keep thinking about putting all of it together in a database, but just haven't got around to it.
Nice to be able to go back and look at previous chrono data.
From what I understand there are two kinds of chrono users, those who have shot theirs, and those who will sometime in the future.
BTW, take a couple spare chrono batteries to the range with you, mine gets flakey when the battery is weak.
When I am at the range the nearest battery to buy is at least 1/2 an hour away....
(and the closest ones at a gas station are way over priced)
Pain to have it go bad on you......
