The Kestrel Elite Weather Meter with Applied Ballistics which has been referred to as the Kestrel 5700 Elite is an updated version from the Discontinued Kestrel 4500 Applied Ballistics Meter in November of 2015. That being said... functionally you're not getting more environmental or ballistic features. So don't feel the need to upgrade unless you find the other exciting changes necessary. - What's new with the Kestrel Elite Weather Meter with Applied Ballistics over the previous Kestrel 4500 Applied Ballistics series: - Bluetooth LINK to Smartphones / Mobiel / Android / IOS - Takes 1 AA battery (instead of 2 AAA) - Battery door is in the back sealed away from the motherboard should your battery leak as was common with all the 4000 series - Improved high resolution screen for any lighting (even sunlight) and easy on your eyes. - Intuitive user-interface screen navigation - Multiple Languages: English French German Spanish - Scratch and breakage-resistant window - All meters include both options of Red (NV - Night Vision) & White backlights. - Slightly bigger not really noticeable difference.
