I use a stalker Pro Radar gun (it's for sale) and when I am alone, I just put it on a tripod. The gun has a max speed hold feature so it will hold it's highest speed and display until you clear. Iused to use it back in the day to radar Jet Skis for race applications. Now we just set it up at the end of the runway and let the hot rodders make high speed passes at it. If anyone is interested in purchasing it, please PM me as Ihave no use for it anymore. This is the same one police used before lasers became all the rage.
I sent you a PM, I'm interested.
