First Impression
This is Guarder's first attempt at a chronograph and they have done an admirable job. We are using this chrono quite a long time at NLAIRSOFT.COM for reviews and actually it never disappointed us. The chrono arrived in a well made white box which has been specifically designed to stop parts moving about and getting damaged in transit. I was at first concerned about the powersupply since this chrono works with a 12V powersupply, however some little transformers solve this issue.
Performance
Common well known problems with chrono's are: inconsistency, dependence on specific light sources, velocity limits and easy to damage parts. The Speeder 2000 suffers from none of these problems. There is a tube running through the unit through which you fire the bb. This tube has a small funnel fitted to it so that you have some protection against the screen being shot out by someone missing the hole. This chrono is rock solid and can hardly be damaged during your FPS tests
Consistency is very good compared to other chrono's in the field. The Speeder 2000 can be used with indoor and outdoor lighting with no problems. Above all there are no velocity limits on the chrono and the highest result I've had sofar was 630 FPS off of the KJW M700 on green gas. The Speeder features 3 different scales to measure velocity: Meters per second, Feet per second, Joules. You can easily switch between these modes. This will suit all people and is really convenient for those joule limits nowadays.
Unfortunately there is not a rate of fire function on this chrono, that would be perfect and very complete when this was combined for this price. Maybe a second model or an update on this model could make it possible.
The chrono can be charged and then used under its own battery power. The internal battery will last for four hours of use. T his featurecombined with the ability to be used in practically any light conditions (including night time) make this an extremely portable and versatile chronograph.
Conclusion
Overall this is a great little package and I recommend it to anyone who is looking for a precision chrono for power testing. Certainly good value for money and hopefully a rate of fire function will be added in the future.
