I was reading Andy Collins' (Armadillo Racing) newsletter yesterday and he mentioned this product in passing. I know someone was looking into track signaling and I thought this warranted a look-see.

If it's not specifically in SCCBC, please pass it along if you know who's looking into this.

Certainly an interesting product, but I don't know of many formula cars that have room anywhere visible for a box that's
8X4x3".  Agassiz has been using Raceceivers for years very successfully , and they're a fraction of the cost.

drivers would need to purchase their own ear pieces to go with the system, and the receiver gets tucked in the car wherever it would fit.

At least it's a start at looking at what's available. We've been talking about this kind of thing for a few years, but we haven't seen much result.

Something like this is going to be required sooner or later.
