While that's a nice set up, I wouldn't exactly call it convenient for the range. The garmin stays in my range bag and barely takes up any space.
The new LR release seemed very rushed and reactionary - Garmin beat them to the punch and they knew it. The caldwell screen seems incredibly small compared to the overall size of the unit. It's nice to see other options out though, as I would imagine this may help drive costs down a bit. So if looking for a new chrono, there are plenty of choices. If the original LR still works great, I see no reason to change. I wasn't impressed with mine - I tried all the tricks and still had plenty of missed shots and connectivity issues with the app. I don't regret selling and going to the Garmin at all.
