Probably worth pointing out, these things are bulky and weigh a lot more than the GPS transmitters available from rocket vendors like Missileworks and Eggfinder.
It'll fit in a 2.6" body tube, but it takes up a lot of it. And if you're measuring ounces to stay as light as possible, this is the wrong tool. In something like a 4" rocket being brute-forced up on an M, there's room in the rocket and the weight won't matter so much.
It's yet another option that, based on one flight, can be used in rocketry. I like it because of its simplicity. And the battery lasts more than 8 hours.
My primary tracker in the rocket was a T3 in the nose. Using it with Rocket Track (similarly using a Eggfinder with bluetooth) allows me to see where over the field my rocket is, track altitude real time, etc. These also let me know if the drogue is out, the main is out, etc based on descent rates from the altitude readings.
The LYNQ doesn't show vertical distance. Only two dimensional. But it is super simple and accurate showing where the rocket is in a horizontal direction.
