Mike – I am interested in your set-up and mount on the rail. Ive wanted to add another unit at the console – probably an HDS8. What RAM mount and base are you using? Does the weight of the unit shift the HDS 10 on the rail in rough water?Thanks in advance for your insight!PatrickLast edited by PIV Patrick on January 9th, 2012, 12:14 am, edited 1 time in total.
