  The Chelton EFIS-SV Sport was released at SNF last year and is based off
  the original Chelton system.  It is a dual-screen system ($25,900) or
  now available is the EFIS-SV Pilot which is a single screen system
  ($15,900).  Both systems use the new Crossbow 425EX AHRS which was
  developed by Crossbow for Direct-To Avionics specifically and
  incorporates proprietary aiding algorithms which were developed by
  Chelton.  We've eliminated the hockey-puck gps and have a WAAS-enabled
  gps which resides in the AHRS enclosure.  They also include an ADC,
  wiring harnesses, data transfer SmartMedia card, install manual, POH and
  our new training DVD.  The EAU (engine airdata unit) has been eliminated
  in the Pilot & Sport, however if you purchase a Grand Rapids
  EIS-4000/6000, they will install our software and you can graphically
  display engine monitoring on the screen.  The Pilot & Sport is
  distributed by us or through an authorized dealer
  (www.d2av.com/dealers.html)
  
  The Chelton EFIS-SV Pro has been upgraded to use the same certified
  screens as the FlightLogic (but without the TSO label on them).  The Pro
  uses the Crossbow 500GA which also uses exclusive algorithms developed
  by Chelton for aiding.  It uses the Garmin GPS or optional certified
  WAAS GPS (Freeflight) which is certified for the handful of precision
  GPS approaches out there.  It includes the EAU for Engine Monitoring and
  Air data.  The Pro is only available through a handful of high-end
  avionics shops such as Aerotronics (www.aerotronics.com
  <http://www.aerotronics.com/> ), Avionics Systems (www.avionikits.com
  <http://www.avionikits.com/> ), Lancair Avionics
  (www.lancairavionics.com <http://www.lancairavionics.com/> ), etc. etc.
  
  Many have asked if the Crossbow 425EX will work in a IV-P.  We have
  recently conducted flight testing on the new AHRS in a customer's IV-P.
  The AHRS was cold-soaked and flown to FL240, -18 deg C, 315 TAS.  The
  ahrs worked flawlessly throughout our series of tests (which exceed
  those outlined in DO-160B).  We've had at least 10 subsequent flights in
  the IV-P with the AHRS and have not been able to fail it.  The 425EX
  remains installed in the IV-P.
  
  The Pilot, Sport & Pro use the same FAA certified (Level A) software as
  the FlightLogic EFIS.
