Everything you need to know about the Speed Demon XT

 

What is the Speed Demon Xt?

The Speed Demon Xt is a speed bag display device that tracks the movement of your speed bag. It can tell you how fast you are punching the bag (in punches per minute), the number of punches you've thrown, or even help train you.

 

WHAT TYPE OF PUNCHING STYLES ARE RECOGNIZED?

The Speed Demon Xt can distinguish between single striking (e.g. fist rolling), double striking (fists passing through), and triplet style (the basic rhythm) in real time.  The Speed Demon Xt can also distinguish between punches and rebounds, and SDXt iMetrics tracks both punches and rebounds.

 

Does it interfere with my speed bag?

No. The Speed Demon Xt uses infrared light beams to track your bag.  

 

How big is it?

It is about seven and a half inches in diameter, and a little more than one-half inch thick.

 

Will it work with my speed bag platform and swivel?

The Speed Demon Xt mounts easily onto any wooden platform using three small screws. The Speed Demon Xt is compatible with the SwivelTek LTX swivel, the Deville 13 Swivel, and most other swivels that fit within a 3 inch square.  

 

Will it work with my speed bag?

The Speed Demon Xt works best on medium or small speed bags. A band of calibration tape (included) will need to be applied at the upper neck region of your bag to help the Speed Demon Xt see your bag (unless you are hitting a red speed bag). 

 

How is it installed?

It mounts underneath your platform using three small screws. If you decide to remove the Speed Demon Xt later, the hole placement will not interfere with your speed bag.

 

How fast people can hit their bag?

Most amateur users can consistently punch at 120 ppm (punches per minute) or higher, using a medium size bag, using the triplet style. More experienced users, using a smaller, professional bag and swivel, can achieve higher speeds, well over 250 ppm, particularly when using a fist-rolling style, where speeds over 500 ppm can be achieved with practice and skill.  Be sure and check out the speed bag records section of this site.

 

How can I compare my performance with my friends?

The Challenge Mode (see below) is a good way to measure your skill because you have to hit the bag faster and faster as the level increases (and your arms get more fatigued!). Not only will it give you a great workout, it may even earn you bragging rights.

You can also gain Speed Endurance ratings by using SDXt iMetrics. Speed Endurance ratings are generated automatically when you workout using iMetrics.  They measure a combination of how long and how fast you have hit the bag. 

 

How many punches will the Speed Demon Xt track?

The Speed Demon Xt will track up to 999,999 punches per session. After you reach one thousand punches, the display measures punches in the thousands, using the decimal point to help you determine how many punches you have thrown (e.g. 1.79 equals 1,790 punches). 

 


Challenge Mode

Challenge Mode focuses on a puncher's sustained speed, rather than instantaneous speed. It tests both endurance and speed.  The Challenge Mode will give you one of the most intense workouts on a speed bag you have ever had! 

How is it played?

Challenge Mode starts at Level One, with five free points.  Each time you punch at the minimum speed required for that level, your point score will increase.  Reach one hundred points for that level and you advance to the next level.  When you advance to the next level, the minimum speed increases.  Fail to keep up and your score will drop.

A key to successfully advancing when playing the standard challenge mode is taking well-timed breaks.  While you will lose points when resting, the rest you take will typically allow you to advance higher than simply trying to punch non-stop, even taking into consideration the extra punches you will need to throw to regain your score.

What is the difference between basic challenge mode and expert challenge mode?

Expert challenge mode is only available using SDXt iMetrics (free app).  It is significantly more difficult than the standard challenge mode.  

When in expert challenge mode, your points will only increase one point for every three rebounds, rather than punches.  However, the minimum speed required to advance is still based on your punching speed, not rebound speed.  

In addition, the minimum speed required for each level advances much more quickly than standard mode.

Last, but not least, the point loss for second of break is six points per second, rather than two points per second.
