Introducing the Brand New Dual Stack Dash Slider Mount. This mount is the most versatile Dual Stack mount for the dash configuration of the Ranger Deep-V model boats. Once the mount is installed, it allows the top and bottom row Slider Plates to be able to better adjust the height of the Sonar Units and get them closer together. This feature also eliminates the old bottom row fixed position, which in some cases would interfere with switch operation and also your knee was subject to hit it.

The other neat feature is the top and bottom Sonar Units can be slid to the left and right to fine tune the position of your Sonar Units. BBT has tested every model and these are a big improvement to the older style mount we offered. This set-up allows you to use the BBT HD Gimbal Brackets that are the "Shorty" style to get the Sonar Units closer together.  You can also use the regular height gimbals brackets.
