Hi,

The LXNAV S8, S80, S10 and S100 variometers are the best varios available. They are well designed and more reliable than any other currently available variometer. The built-in AHRS hardware makes them easy to install and reliable. LXNAV developed the AHRS hardware - they didn't tack-on an external AHRS unit. The varios fully replace older vario systems like the Cambridge 302/303 system, ILEC SN10, etc. They are available in either 57mm or 80mm sizes with exactly the same functionality in either size. And they use a single instrument hole instead of 2. They offer excellent variometer functions as well as waypoint and task navigation, FLARM and ADS-B traffic display and warnings, and final glide calculations. They also have built-in g-meters as standard. Also, with the current exchange rates, you can get an S8-Club speed-to-fly variometer for $870. That is much lower cost than previous speed-to-fly variometers. I also like that you can buy a "club" version with the same hardware and add software features easily at any time in the future. Also, the AHRS enable is a software enable that can be done easily at any time. They work great with FLARM units and Naviter Oudie units too. I very highly recommend them. I do sell them, but I also fly with them.

I have actually used the s100 in my DG 100 for 1 season. I popped for the AHRS as well. 80mm is the way to go.

This is a huge difference between the two brands. LX Nav does not let you revoke the AHRS key, which translated into normal human speak means that you can't take your AHRS with you. So if you sell your unit to someone else because you want LX Nav's latest and greatest, or just your unit conks out, you're SOL for the $$$ you spent. Every time you get a new model you have to spend $800.

LX Navigation has a separate AHRS module which is portable to new installations.

Frankly, and this is speaking as an embedded guy who's been doing drone autopilot firmware since 2010, LX Nav has destroyed a lot of the value of their product for peeps who want an AHRS. Unless their internal software is a dumpster fire, which is its own problem, fixing this lack of portability is a perfect first task for an intern/junior engineer.
