Sweat proof Guard hit cancellation
Sweat proof Guard hit cancellation
Hits to the guard are cancelled. These will not register as a hit (no hit light or buzzer will sound). The guard hit cancellation circuit will never confuse a sweaty jacket, a sweaty glove, a sweaty mask, even sweaty skin for the guard. There will be no mysterious cancelled hits that plague most wireless systems. When testing the guard hit cancellation, try to hit the guard with a bit of speed, as if it was a truly hit during a bout. A slow mild hit may still register (however this is unlikely in an actual bout). Some grazing hits to the guard may still register.
It is ok to use a mask with chipped paint or even a mask with no paint at all (hitting these will register a hit as usual).
The sensor exploits the magnetic properties (instead of conductive properites) of metals to determine if the guard was hit. It is simply immune to sweat.
Floor hit cancellation. Metallic Piste NOT needed!
Floor hit cancellation. Metallic Piste NOT needed!
Strong hits to the floor are cancelled. These will not register as a hit (no hit light or buzzer will sound). You do NOT NEED A CONDUCTIVE PISTE for the function to work. Weak hits to the floor will still register a hit. Generally most missed foot hits that hit the floor/piste are quite strong, especially when fencers are infighting and doing remises. The floor hit cancellation function is helpful in these situations to minimize unnecessary stoppage of the bout.
The floor cancellation works best on hard wood floors, concrete floors, tiled floors and of course will still work on metal (Aluminum) pistes. If you wish to roll out a rubber piste, please use the thinnest one possible. Rubber matting will degrade performance.
The floor hit cancellation can sometimes confuse a strong flick hit to the mask as a floor hit, especially on the harder curved areas of the mask. Straight hits to the mask will still be signalled as usual. (Flicks or straight hits to any other part of the body will be signalled as usual). We believe this is a small trade off for less disruption occuring from floor hits as flick hits on the mask are kind of rare. You can always deactivate the floor hit cancellation function if needed. In this case any type of hit to the mask will be signalled.
Practical Plug and Play
Practical Plug and Play
Plug the units to your epees and start fencing! Units will communicate directly with each other. No need to pair and unpair to a central unit or smartphone. No need to set up a table at the center. No need to calibrate.
Use cases:
Useful for training locations that are not permanently made for fencing.
Fence at home or at the park with friends.
Practice bouts on the competition venue right before the actual competition
The ease of use makes this ideal for training a salle full of excited youth.
Useful as a tester too
Sleek
Slim profile will not crowd the inner guard
Very Visible
Very Visible
The whole 5x4 cm front face lights up through a silicone light diffuser visible from any angle.
Bright LEDs at the rear face light up the inner guard area for extra visibility.
Adaptable Clip
For larger clips, swing the filler for a better fit.
Spectators
The devices are plugged on your weapons, where you, the umpire and the spectators have their focused view. A quick blue light (with no buzzer) will illuminate on your unit if you get hit, just in case you don't notice your opponent's light.
FIE compliant lock out timing and point depression timing
FIE compliant lock out timing and point depression timing
Complies with FIE lock out timing rules (40 mS)
Complies with FIE point depression duration rules (2 to 9 mS).
Unit can be serviced if there are rule changes.
Tough!
The front face and electronics are encased in a 6mm block of solid collision absorbing silicone resin. A unique lamination process integrates the thin cover with the silicone to make one continuous solid object that will withstand direct epee hits through the years. (Unit on the right shows the silicone block without the top cover).
Slim Sides
Slim Sides
The rear face has a thickness of less than .5 cm . This will not crowd the inner guard and touch your hand. The whole unit has a thickness of only 1.2 cm.
Long Life User Replaceable rechargeable Battery
Long Life User Replaceable rechargeable Battery
Onboard LiPo rechargeable battery lasts more than 2 hours of actual fencing. The unit will go on standby automatically if no hit is detected for 8 mins. Rechargeable batteries can be replaced by a competent armorer (simple soldering required). The 401030 LiPo battery is very common and can be bought in eBay or AliExpress at an economical price.
Personalize

The front face is sticker friendly. You can affix transparent stickers of your club or country.
Light Weight

Weighs only 39 grams. Not much more than your typical connector
Reliable Radio
Reliable Radio
Uses a simple and very reliable radio transceiver. Unlike Bluetooth and Wi-Fi there is less radio traffic on these frequencies. There is no complex data addressing and frequency hopping. No delay in hit detection or lock out signaling in areas with lots of smartphones like malls or exhibition areas. 25 channels allow up to 25 active pistes. Channels are pre-set. If you buy more than one set the other sets will be set on a different channel at the factory. The pairs will have a color code on the side to avoid confusion.

On sweat tolerance of wireless fencing devices
Wireless scorers are affected by sweat. Some more than others. This is because conductive properties of metal are used to distinguish whether the guard is hit or not. Unfortunately sweat is quite conductive as well. If there is enough sweat on your jacket or gloves, the scorer confuses this for the guard and will not register an otherwise good hit. It is for this same reason some scorers fail to register a hit on masks with chipped paint (which is pretty much the case on all but brand new masks) or on bare skin. It is important to realize that your clothing does not need to be very wet with sweat for failures to start happening. When sweat dries, it leaves salts and other minerals on your clothing, especially the gloves and bib where they are not usually washed. These tend to accumulate and become conductive even with a small amount of moisture. Failures happen sporadically at first, which quickly becomes very frustrating, then you start to doubt if other hits were supposed to have gone in.
We guarantee that the Cito wireless epee scorers are absolutely unaffected by sweat. The first generation of Citos did not have guard hit cancelation functions. We believed consistency and reliability was more important. We waited until new sensing technology was available and we were able to develop an absolutely sweat proof method of guard detection. We use magnetic properties or metal to determine what was hit. Sweat does not have magnetic properties at all (in fact its the opposite).
We hope you are informed of this topic before you purchase any wireless scorer may it be the Cito or not.
