RDAS Classic

My favorite altimeter
First Flight: Vector 2
Highest Flight: 11,700 feet
Type: Barometer & Accelerometer
Apogee: Accelerometer
Main: Barometer adjustable
Downloadable Data: YES
Graphics Software: YES

 

This has to be one of the best altimeter out there on the market. On its first flight on the Vector 2 it was in a rocket that totally shredded apart. The altimeter felled out of the remains of the rocket and fell 1500 hit the hard desert dry lake bed When it hit the CPU chip and buzzer fled off. I order a new CPU and solder a new buzzer on the board and it still works to this day. In fact it was been in rockets that has flown as high as 11,700 feet and as fast as 900 MPH.

The board is expandable with add on board and is software upgradeable. Which I have done several times since I first got it. You can get addition igniter boards, GPS board, Telemetry board, and a 2 Ariz. board.

GWIZ DELUXE 800

First Flight: Vector 3
Highest Flight: 11,700 feet
Type: Barometer & Accelerometer
Apogee: Accelerometer
Main: Barometer - Fixed 800 feet
Downloadable Data: NO
Graphics Software: NO

This was my back up altimeter for my level 3 certification flight. Which was needed when the main chute charged didn't fully deploy the main parachute. It has always fired its charges. I am not sure but of the high altitude flights it might be firing the apogee charge too soon while the rocket is still climbing at a fast rate. The only draw back I have to this altimeter is it just uses blinking lights and there isn't a beeper on board. You have to make sure you double check everything before you button up your rocket.

AltAcc 2A

First Flight: City of Pittsburgh
Highest Flight: 4200
Type: Barometer & Accelerometer
Apogee: Accelerometer
Main: Barometer - Fixed 600 feet
Downloadable Data: YES
Graphics Software: YES

Damage during hard landing.

My first altimeter, it is a easy altimeter to mount to a rocket and the LED can blink out though a hold in the side of the rocket. The arming switch is built right on the board and can be armed with a simple screw driver. I don't have too much history with this altimeter since it was damage during a landing when I didn't have enough eject charge BP to deploy the main chute. I have bought the new AltAcc 2C to fly on board the rebuilt Vector 2A

Prefect Flight WD

First Flight: Hy Tech 80
Highest Flight: 2,300 feet
Type: Barometer
Apogee: Barometer
Main: Barometer - Selective 300 though 1500 feet
Downloadable Data: YES
Graphics Software: YES

This little altimeter is my small but so far been VERY reliable. It has always fired it charges and return my rocket safely to the ground. It is an barometer fired altimeter so you do have to worry about going though Mach, but there is an mach delay switch to prevent premature firing of the apogee charge. The main deployment charge is selective from 300 feet to over 1500 feet in 8 different steps. With its small size it can first pretty much in any size rocket. And it has a very good battery life I have seen these altimeter still beeping out its altitude after 24 hours.
