Review on Mount RAM B 138U Double Ball Surface by David Cash

I needed to install a GPS module on my snowmobile. It's not an easy installation process as the snowmobile absorbs incredible shock and really bounces. I was concerned that the leverage would cause the GPS to constantly misalign with each hit. To my great surprise, I never had to make any adjustments. The strength of this single handle to apply sufficient clamping force was excellent. I recommend this type of mount as it is very reliable. The main mounting plate is also very versatile and can accommodate many different screws. Be sure to check out the full range of device mounting plates available for specific GPS or cell phone mounts.
