SMO2 Monitor
 

I was debating on whether or not to buy a BSX Insight 2.0, unsure of it's accuracy and legitimacy? I assume it's accurate and I also assume it could be a valuable tool when looking at intensity of intervals as well as climbing VO2.

Again I'm thinking if used properly it can condition one to think more from a muscular performance standpoint.

I also heard they are discontinuing the product line, if anyone knows why I'd appreciate the knowledge.
