Actually, its fairly simple . . . use a chrono that doesn't use screens
The MagnetoSpeed uses 2 magnetic sensors on a bayonet that are not sensitive to muzzle detritus.
The LabRadar uses Doppler radar and is not affected by muzzle blast detritus. Whether this is facilitated by the unit's tracking the projectile far down range (up to ~100 yards) or not, I don't know - but it works fine.
Either one gives useful data without carting 6' of chrono to a daylight-only, outdoor shoot and waiting for a cold range to set it up.
The MagnetoSpeed's "only" drawbacks are it needs something to attach to (most often a barrel) and when attached to a barrel it will most likely change your POI.
The LabRadar's "only" drawback depends on it being able to distinguish between your firearm's report and those of other shooters. While shooting suppressed in a war zone might be problematic, other situations I've encountered (including indoor use) have not posed any issues.
Those two units carry at less than 2 pounds and occupy less than 1/3 of a cubic foot of space. They set up in seconds while the range is hot and operate in any lighting or weather. They are also extraordinarily difficult to shoot
Are they as accurate as an Oehler 2-by-chrono? Only time will tell. Most people who don't have an Oehler don't seem to care.
