## Overview

The Jolly Logic AltimeterTwo is a cutting-edge rocket altimeter designed for serious hobbyists and professionals. Measuring peak altitude up to 29,500 feet and top speed in MPH or KPH, it features a compact form factor (just 0.57 x 0.71 x 1.93 inches) and rechargeable battery via USB. Its advanced sensors deliver 10 critical flight analyses per launch, storing data from the last 100 flights on a sunlight-readable LCD. Durable and versatile, it mounts in nearly any rocket, making it the ultimate tool for precise, data-driven rocketry.

## Description

An awesome gift for anyone who is into rocketry. This is the second generation of the Jolly Logic AltimeterTwo, the ultimate rocket flight analyzer. New in this version are a bitmapped, animated display, larger battery, and a History feature which saves the last 100 flights. Amazingly tiny and incredibly powerful, the AltimeterTwo uses state-of-the-art pressure and acceleration sensors to perform 10 key flight analyses for each rocket flight, including altitude, speed, acceleration, coast time, apogee to ejection time, ejection altitude, descent rate, and flight duration. No batteries required: the AltimeterTwo plugs into just about any USB port to recharge. Its durable construction and convenient tether point make this the only rocket altimeter that can be mounted in just about any rocket--even those without a special payload section. Although data is NOT downloadable, every key statistic is compiled and presented clearly on the sunlight-readable LCD screen. For rockets only. Will not work in other types of flying things.

Review: Awesome Altimeter plus computer - For the compactness and features this Altimeter Two has is awesome! Plus it provides a lot of other information such as max thrust, avg thrust, coast time, time of ejection after apogee, descent speed, max speed, and total duration. I love it for redundancy if using a dual deploy onboard computer as it displays numbers and one does not have to count beeps. The USB port is only for charging and not for transferring data. Nonetheless, it is a great addition to make rocketry that much more entertaining and scientifically useful. The button seems challenging to press but once one reads the instructions it is clear just press it like you would normally and it will activate. The display needs to be read at the proper angle as it is not that bright. But it keeps the information as long as it has power so you can read it in better lighting conditions. I was able to use it on two other launches and it worked great even when the nose cone came off but the parachute was stuck inside the rocket. It said the rocket descent speed was 57mph! Alas, it was a 6' long Estes Mean Machine so it is now about a 5'6" Mean Machine and the Altimeter two that was wrapped in 1/2" pipe insulation and a rubber band suspended from the nosecone works great! The only issue I had is I could not get it to charge. After reviewing their website support page I found on tip was to use a USB extension cable and after trying it in 6 different USB ports on two computers I was ready to give up. I even had it fail on a trip to ROCstock due to battery drain. Nonetheless, I the cable works and I now have it fully charged and ready to go next time.
Review: Best mini altimeter out there! - Much more reliable and accurate than the Estes version, plus a massive amount of data comparatively. Yes, it's more expensive than the "toy" option, but it's worth it if you really want to collect data about your launches. The Estes one is fine if you just want a fun toy to see how high your low-power kits got, but be warned that it doesn't seem to be as accurate overall. One other thing that the instructions cover, but I want to remind you. If you don't vent your rocket with at least two small holes, the pressure inside the model won't match the outside pressure, and you will not get accurate readings. I know some people might not like making holes in their perfect paint jobs, but if you want any altimeter to be accurate, you need to do this. Just find two unobtrusive places and drill small 1/8th inch holes in the body tube.

### ⭐⭐⭐⭐⭐ Altimeter Two works great and is easy to use
*by E***. on April 21, 2013*

We purchased the Altimeter Two so that my son could do his science project with homemade rockets. I didn't think we needed this altimeter because it offers a lot of data - more than I thought would be useful. Even though we could have lived with the simpler version, this altimeter is awesome! It records so much and really puts the life of the rocket launch in to workable data. Overall, it is really simple to use and very hardy. We did create a little "booty" for it. We cut up an old sock, stapled it and slipped the altimeter in to give it some extra protection. We had a few failed missions where the parachute didn't open and the altimeter worked well and didn't appear to have a scratch on it. Just be sure to charge it before launch and turn it on before you go. You won't be disappointed.
