Jim H and Jim, I wonder if this generation of glider guiders could even find or center a thermal using a simple mechanical vario lol How far we have advanced but also how far we have digressed in skills.

In the olden days we flew with slower, lighter gliders, so a slower vario without
audio worked fine. Now we cruise at 90 kts and thermal at 60 with full ballast.

But even then, pilots were using TE and Netto.
