Smallest Altimeter for a 13mm Body Tube

[Harrison Vance]

Looking to see what's out there that fits this body tube. Let me know if you know of anything that does. Thanks!

I think the FlightSketch Comp would fit based on published dimensions, but they are currently reflecting Out Of Stock on the manufacturer's site... https://flightsketch.com/store/catalog/flightsketch-comp_229/

David is correct, the Flightsketch Comp does fit but has been out of stock. The Adrel altimeter sold my North Coast Rocketry also fits in 13mm tubes.

I'd heard mention of the Adrel in other posts, but apart from that am completely ignorant of it (specifications, etc.). Thanks for the reminder Jim.

Yup, those are the two that will fit - FS Comp and Adrel ALT-BMP (AKA North Coast MaxAlt). In the Adrel's case the li-poly cell sold to power it is really the tube size constraint. FS Comp will fit in BT-4. In this image, Adrel in upper left, FS Comp in lower right. The others are FS Mini (upper right), Altus Metrum MicroPeak (lower left), and PerfectFlite Firefly (lower center). None of those three will fit easily in BT-5 (13mm) tubes.

Thanks for the visual help Bernard! I didn't know there were so many to chose from!

Great resource!

Are there any NAR competition-certified altimeters, for 13mm tubes, with deployment ?

Just bought the North Coast MaxAlt. Fits the 13mm body tube easily and is known as the smallest altimeter on the market. It’s verified and used in competitions for the NAR to my knowledge. I’ll be using it at NARAM-63 this year. Hope that helps!

MaxAlt is no longer the smallest. The FS Comp is. See the image in my post #6 above. FS Comps were used quite a bit at NARAM last year. However, (sadly) the MaxAlt might be the smallest one you can actually get right now, thanks to supply chain madness…..

My apologies on the mixup. I ordered the FS comp. It is indeed the tiniest one on the market.
