[vslist] Riverbend vs. CNC eye coil systems

[David Bradley]

I have both CNC and Riverbend scleral coil systems. So far the CNCs have
been a hassle, mainly because they saturate the gain stage of our (plexon)
headstage buffers, which lowers S/N. Also, the offset adjustments often are
unable to zero the signal, even though we know the scleral coils aren't too
far off center.

But I haven't analyzed eye position data thoroughly for either one. Before I
unload my CNC systems, does anyone know of advantages of the CNC (vs
Riverbend) that I'm not aware of? For example, are the CNCs simply more
accurate? More linear? More stable? More durable? (etc). Are there other
systems I should consider?

Thanks.
