GPS speedo

[Dreadstar]

What do you use for measuring the speed of your various vehicles? I'm looking for a small GPS unit to use in my Fury.

These two seem popular, but I have a hard time dropping even only $65 (much less $150) on a device just to measure speed... thus far I've used an old iPhone LOL

SkyRC GPS $65 - https://www.amazon.com/SkyRC-Speedometer-Altimeter-Quadcopter-GSM-010/dp/B00SA2JQL4

Garmin Foretrex 401 $150 - https://www.amazon.com/gp/product/B002EOSQII

I have an old Garmin eTrex Legend I just dug out, but I don't know how quickly/well it can measure changes in speed, I may give it a few runs just to compare and see. I'd rather have that at risk then even my old iPhone.

I use a Garmin foretrex 401. If looking for cheaper and without the added weight, speed gun works well...but you'd need a gff / bff / bystander to help out.
