\tThis upgrade is for any of the Marq Series of Bob Long markers (Marq 6, Marq 7, Rapper, Closer)<\/span>
<\/p>\n

\t
<\/p>\n

\tThe biggest advancement to the paintball marker since the inception of the 2 eye upgrade<\/span>
<\/p>\n

<\/p>\n

\tThe
\nset of eyes at the top of the breach reads the ball drop rate and tells
\nthe bottom set of eyes when the ball will be in place and ready to be
\nfired, rather than waiting for the bottom set of eyes to read a ball in
\nplace and then firing.  This action speeds up the firing sequence
\ndramatically<\/p>\n

4C System Enhancing Eyes Theory and Functionality

\n\t\t\t\t\t\t\t\tFor
\nyears, high performance paintball markers have minimized paintball
\nbreakage by using a break-beam infrared sensor system commonly known as
\n\u00e2\u0080\u009ceyes\u00e2\u0080\u009d. These eye systems are traditionally positioned at the bottom of
\na markers breech. Single sensor eye systems will only allow a marker to
\nfire when a paintball has finally rested on the bottom of the breech,
\ntherefore breaking the infrared beam and communicating \u00e2\u0080\u009cfire\u00e2\u0080\u009d to the
\nmarkers micro-controller. A broad spectrum of controlled testing has
\nproven this current eye system to be the predominant limiting factor
\nwhen seeking out maximum rate of fire potential. Our engineering staff
\nat Bob Long Technologies has successfully implemented an advanced
\nsystem of optoelectronics which can increase a markers cycle rate
\nalmost 40%. The multi-sensor 4C System Enhancing Eyes define the
\nabsolute cutting edge in electronic marker technology.<\/p>\n

\t\t\t\t\t\t\t\tThere are
\ntwo instances of wasted time in a markers firing sequence (cycle time).
\nOne instance occurs during the time taken for a micro-controller to
\nenergize the coil of a solenoid. The second instance occurs during the
\ntime taken for a markers bolt to respond to the recently transferred
\nair pressure. This combined time can be 20mS or greater. A marker
\ncycling at 20 balls per second has a cycle time of 50mS, so 20mS would
\naccount for 40% of the total cycle time. Using multiple sensors around
\nthe breech provides the information needed to accelerate the cycle
\ntime. A sensor near the top of the breech indicates whether or not
\nanother paintball is ready to be loaded. A sensor near the bottom of
\nthe breech indicates whether or not a paintball is properly staged and
\nready to be propelled. These sensors working in tandem provide us with
\nvaluable time measurements and other consistency data. Because we now
\nknow how long it takes paintballs to move down through the breech into
\nthe final staged position, we energize the solenoid coil early so when
\na paintball reaches the final staged position the bolt has begun its
\nforward movement. This timing adjustment, made possible by 4C System
\nEnhancing Eyes, eliminates all wasted time in a markers firing
\nsequence.  <\/p>\n


\n\t\t\t\t\t\t\t\t4C “Play and Play” <\/p>\n

\t\t\t\t\t\t\t\tHere is a more
\ndetailed description of how the 4C System Enhancing Eyes work. The time
\nit takes for a markers bolt to move back past sensors toward final open
\nposition, allowing a paintball to fall, will be recorded. The time it
\ntakes for the next paintball to pass by the top sensor while falling
\nwill be recorded. The time difference between these measurements will
\nbe calculated by the markers micro-controller and a paintballs falling
\nvelocity will be obtained. This falling velocity will indicate if the
\nhopper being used is force-fed or gravity-fed. Use of a force-fed
\nhopper will result in the much higher falling velocity of paintballs.
\nForce-feeding also provides the best estimates of time required for a
\npaintball to fall into its final staged position. Because vital
\nmeasurements have been obtained by the 4C System Enhancing Eyes a
\nsolenoids coil can now be pre-energized, factoring for mechanical
\ndelay. Use of a gravity-fed hopper will result in a slow inconsistent
\nfalling velocity. If a gravity-fed hopper is detected the
\npre-energizing sequence is ruled out by the micro-controller and only
\nthe bottom sensor will be used in processing when the firing sequence
\nshould begin. Assume it takes 15mS to get a markers bolt moving forward
\n(calculating 20mS for a ball to fall past upper sensor into final
\nstaged position at lower sensor). In this instance the solenoid can be
\nactivated 5mS after the upper sensor is triggered. 15mS later the
\npaintball will reach its final staged position at the same time the
\nbolt has begun its forward movement. This cycle timing adjustment, made
\npossible by 4C System Enhancing Eyes, eliminates all wasted time in a
\nmarkers firing sequence. <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n
