I've made my first jump with my Altitrack in 2007. I bought it because I'm really in to gadgets, but it's more then just a gadget.
I like to simplicity on the "analog" side. During freefall you don't need to know your exact altitude and the big numbers and the colours (4000ft and below) make it easy to read.
On the other side (inside) it has a very easy to use and extended logbook. I personally don't use the playback functions. Just freefall time, heights and speeds.
Like some other people wrote before, I also had some problems with the software which L&B fixed very fast and appropriate.
So here are a couple of things I don't like about the Altitrack although it is an awesome altimeter and highly recommended!
- I used it in 2007 and 2008 for about 31 jumps. I didn't jump some years and started again in 2012. This year (2013) I had to replace my battery.
- I don't like the Jump-Track software. It has a very old fashioned look and it is not really user friendly.
- Some jumps with a short freefall (hop & pop) where not detected by the device.
- I would like to see a different way to attach the finger loop. The current velcro doesn't work 100%.
That said, I love my Altitrack and my other L&B products! This product is highly recommended.
