Are you looking for some high tech payloads for your rockets? Check out these items:

• AltimeterOne Altimeter (Jolly Logic 29,500 foot altimeter)
  Our simplest and most versatile altimeter. It is the only one listed here that doesn't require a separate payload bay to protect the altimeter. Just attach it to the bottom of the nose cone like a parachute, and poke some holes in the tube so it can sense the air pressure. Includes a rechargable battery so you never have to worry about buying extra ones. Recharges on any computer USB port. Reports peak altitude only -- does not store flight data.
  
  
• 15,000 Foot Altimeter (PerfectFlite Alt15K/WD)
  This altimeter is used by the TARC competition. It records the altitude of the rocket to an altitude of 15,000 feet above sea level. It includes an option to allow you to download the flight data to your computer after the flight. This makes it great for educational and research projects.
  
  
• 7,000 Foot Altimeter (Winged Shadow System "How-High SP")
  Looking for a cheaper altimeter than the one listed above? This one is less expensive, but it doesn't measure as high (only to 7000 feet instead of 15,000 feet), and it does not store flight data. It only reports the peak altitude of the rocket. It is great when you want just a quick-and-dirty measurement of how high the rocket flew. Can also be used on model airplanes and kites.
  
  
• Dual-Deployment Controller (PerfectFlite Hi-Alt45K)
  A nice barometric altimeter to deploy two parachutes out of the rocket. One at apogee (a small one), and another when the rocket is closer to the ground (a BIG parachute). This allows the rocket to come down close to the pad so you don't have to walk far. This dual-deployment altimeter does not store flight data.
  
  
• Entacore Programable Dual-Deployment altimeter with data logging
  Another barometric altimeter used to deploy two parachutes out of the rocket. One at apogee (a small one), and another when the rocket is closer to the ground (a BIG chute). This allows the rocket to come down close to the pad so you don't have to walk far. This dual-deployment altimeter also logs flight data, so you can look at the altitude versus time curve on your computer after the flight.
  
  
• G-Wiz Flight Computers
  This is more than just dual-deployment of parachutes. It can also be used to stage motors and set off outboard motors in cluster arrangements. It not only uses barometric sensors to find out how high the rocket is, it also uses accelerometers to find the rockets position and orientation. You can even add other senors (temperature, spin rate, etc) and the computer will also log that data so you can look at it after the flight. It is a lot of horsepower that you may need for complex rocketry projects.
  
  
• Staging Timer (PerfectFlite Mini-Timer)
  This is a simple timer that will ignite a second motor in the rocket. Good for mid-power rockets where you are launching two stages. Can also be used for an inexpensive back-up control on other complex projects.
  
  
• MicroBeacon Model Rocket Locator (Pratt Hobbies)
  Fits in small rockets so that you can find them more easily. Emits a loud scream so that you can track it down by the noise. Great for getting your young sister to scram out of your room too.
  
  
• Sonic Rocket Locator (Transolve BeepX)
  This payload emits an ear-splitting siren after the flight is over. The noise helps you get a bearing on where the rocket landed so that you can retreive it more easily.
