Let’s Talk Scanstrut LMB-F2 Self Leveling Radar Mount

Navigating the marine environment demands reliable equipment, especially when it comes to critical safety and navigation systems. My search for an optimal solution for my radar led me to the Scanstrut LMB-F2 Self Leveling Radar Mount. As an experienced gear specialist, I’ve seen my fair share of mounts, but this one promised a significant leap in performance by actively maintaining a level radar picture, even in the most dynamic sea conditions. The primary issue I was trying to solve was the degradation of radar performance caused by boat heel and roll, leading to missed targets and an unreliable display. My initial impression of this self-leveling mount was one of robust engineering. The combination of machined aluminum and marine-grade stainless steel felt substantial and built to endure the harsh marine environment. While I briefly considered simpler, fixed mounts or even custom fabrication, the allure of an active stabilization system for this specific application was too strong to ignore. It offered a sense of confidence and a clear solution to a persistent problem.

Real-World Testing: Putting Scanstrut LMB-F2 Self Leveling Radar Mount to the Test

First Use Experience

My testing began aboard my vessel, a moderately sized cruiser, where the Scanstrut LMB-F2 Self Leveling Radar Mount was installed on the backstay. This was a critical installation, requiring careful alignment with the backstay cable diameter, which thankfully the included nylon bushings accommodated with ease. The initial setup, including the pole assembly and attaching the radar dome, was straightforward, taking only a couple of hours. Performance during a moderate coastal passage was immediately noticeable. As the boat heeled during tacks and experienced minor roll from waves, the radar mount actively compensated, keeping the radar scanner level with the horizon. This resulted in a remarkably stable radar picture, with target acquisition and tracking remaining consistent without the usual fluctuations.

The intuitive nature of the passive hydraulic system was a key benefit; no power was required, and the system reacted smoothly to significant changes in heel angle while effectively damping out smaller, irritating oscillations. There were no immediate issues or surprises, only a quiet satisfaction that the system was performing as advertised.

Extended Use & Reliability

Over several months of regular use, including extended offshore passages and frequent coastal cruising, the Scanstrut LMB-F2 Self Leveling Radar Mount has proven its mettle. It consistently delivers a stable radar display, which is invaluable for both navigation and safety, especially when visibility is reduced. I’ve subjected it to various conditions, from choppy seas that induced significant rolling to lighter airs where persistent heeling is the norm.

The durability has been impressive. The anodized aluminum pole and head unit show no signs of corrosion or degradation, despite constant exposure to salt spray and the elements. The stainless steel cradle remains secure, and the hydraulic damping system continues to operate smoothly without any leaks or performance drop. Maintenance has been virtually nonexistent; a simple rinse with fresh water after sailing in saltwater is all that’s required. Compared to previous fixed mounts I’ve used, which often required re-leveling adjustments after significant weather events, this self-leveling unit offers a superior, hands-off experience. It has far surpassed the reliability and convenience of simpler budget options, providing a consistent and professional-grade performance.

Breaking Down the Features of Scanstrut LMB-F2 Self Leveling Radar Mount

Specifications

The Scanstrut LMB-F2 Self Leveling Radar Mount is engineered for specific radar domes, notably those from Sitex & Simrad, ensuring a precise fit. Its core functionality relies on a finely-tuned hydraulic damping system that actively keeps the radar scanner horizontal relative to the horizon. This system is entirely passive and maintenance-free, meaning it requires no external power source and minimal user intervention after initial installation. The mount includes a 2.6m pole, supplied in two 1.3m sections for easier handling and storage, with optional additional lengths available to suit different mast heights or mounting preferences.

The construction materials are top-tier: the pole and head unit are made from the finest quality machined and anodised aluminium, promising a lifetime of service, while the radar cradle and base plate are forged from marine-grade 316 stainless steel. This robust build is crucial for longevity in the harsh marine environment. The kit thoughtfully includes everything needed for installation: the levelling mount itself with integral backstay bushes designed to fit 7, 8, 10, and 12mm diameter backstay cables, two 1.3m pole sections, a joiner piece, a universal base, and a complete fastening pack. The inclusion of nylon backstay bushings is a practical touch, allowing for cable tension adjustment without compromising the mount’s secure grip.

Performance & Functionality

The primary job of the Scanstrut LMB-F2 Self Leveling Radar Mount is to ensure your radar maintains a level orientation, and in this regard, it excels.
