You get the same resolution and features† that you currently have on the unit you’re upgrading or better! If you have a 160 x 120 resolution TI, you'll be upgraded to a 240 x 180 resolution for free. If you lacked Super Red Hot or Temperature Measurement, it will be added for free. New batteries and a desktop charger are included with every upgrade, as well as a communications port with Eclipse® LDX. Additionally, you can always add features you didn’t have or that weren’t available on your current product.
