What has failed Tacx, Sigma makes right!

After purchasing a Fortius Multiplayer - Exercise Bike initially I was very disappointed that such a high quality and not just cheap device not accompanied by heart rate monitors. Something's today, after all, at any cost-Tacho from discounters to. On the website and in the almost non-existent documentation that comes with the device, are found disappointingly only one "very far-fetched" description about could fit to which heart rate monitor. It says: "analog or digital, uncoded". A list of functioning pulse belts would have been better here. Surely I'm not the only one where it is so issued. After a long search in various forums I came across a belt, in which you can not change the battery. A disposable article, what does that matter?
The sigma belt is strangely enough no mention, at least I've found nothing. After I (various gauges and lamps) was always happy with my previous Sigma products, I got me here the "Sigma chest strap analog (Tacx Brustband Sigma)" ordered.

Pro:
- Is immediately recognized by the Fortius Multiplayer
- Usual good Sigma Quality
- Battery (CR2032) can even be changed
- Textile belt can be bought individually

Cons:
- NO!

Conclusion: All have Fortius buyers who either no, or a coded chest strap (eg Sigma ROX 9), to this heart rate monitor should to order now!
