GeoMax Automatic Level ZAL300 Series
Built for toughest conditions
The ZAL300s class leading optics and magneX™ compensator are imbedded in a sealed and shock protected housing making it highly resistant to bumps and all weather conditions. Even following a short drop the GeoMax ZAL300 continues to works with the same reliability and accuracy.
