For our own testing & shop use we also have a Port-A-Tree timing system that gives us 0-60' et, 0-500' et, and mph @ 500' as well. The Port-A-Tree system is pretty old already (15 years probably) and I don't remember the cost of that anymore! LOL! We just recently bought a Stalker STATS system which incorporates a Stalker radar gun and a laptop and you can pick and choose any distance to see what MPH and ET you are running in that distance as well as graphing it out for you. That type of system costs about $2,200. All for a snowmobile business! LOL!
