Carol Duncan –
Installed the mount on my HOOK2 5x in under 5 minutes. The 360-degree rotation and 15-degree tilting make it easy to adjust the display without moving the whole unit. The material feels durable and the finish holds up well in saltwater exposure. No issues so far after two months of use.
Julia McLean –
Works perfectly with my HOOK2 4x. The tilting feature helps reduce glare when fishing in bright sunlight. The mount is secure and doesn’t wobble during boat movement. A simple tool-free installation that fits well with my existing StarPort base.
Maria Dowd –
Highly satisfied with the fit and function. The rotation is smooth and the 15-degree increments give precise control. I noticed less eye strain during long fishing sessions. The UV stabilized plastic resists fading even after several weeks of outdoor use.
