Why I Changed Simrad Cruise 9 from MPH to Knots

I changed my Simrad Cruise 9 from MPH to knots because knots are the standard speed unit for boating and navigation. When I’m on the water, I want my readings to match what charts, GPS systems, and marine reports use. It makes everything feel more accurate and easier to compare, especially when I’m planning routes or checking my speed against tide and current conditions.

For me, using knots also helps avoid confusion. MPH is fine for driving, but on a boat it can make quick navigation decisions less natural. Knots give me a better sense of how fast I’m actually moving through the water, which is important when I’m trying to stay safe, fuel-efficient, and in control.

Another reason I prefer knots is that it keeps my display consistent with marine terminology. Since most boating instructions, weather updates, and navigation references use knots, switching my Simrad Cruise 9 to that unit makes my experience smoother and more professional.

My Buying Guides on Simrad Cruise 9 Change From Mph Toknts

What I Learned About the Simrad Cruise 9

When I first started using the Simrad Cruise 9, I liked how simple the interface felt. It is a solid chartplotter for basic navigation, and I found it especially useful for quick route checking and speed monitoring. One thing I needed to figure out right away was how to change the speed display from miles per hour to knots, since boating speed is usually more practical in knots.

Why I Prefer Knots Over Mph

In my experience, knots make much more sense on the water. Most marine charts, navigation references, and trip planning tools use knots, so switching from mph helps me stay consistent. I also find it easier to compare my actual boat speed with weather conditions, fuel planning, and navigation estimates when everything is in knots.

How I Changed the Speed Unit on My Simrad Cruise 9

On my Simrad Cruise 9, I went into the settings menu and looked for the units or language section. From there, I found the speed unit option and changed it from mph to knots. Once I saved the setting, the display updated right away. It was a simple change, but it made the unit much more useful for my boating needs.

What I Checked Before Making the Change

Before I adjusted the setting, I made sure I was in the main menu and not in an active navigation screen that could distract me. I also checked the user manual when I wanted to confirm the exact menu path. If I ever had trouble finding the option, I would recommend restarting the unit and checking for software updates, since menu layouts can vary slightly.

Features I Like Most on the Simrad Cruise 9

I like the large 9-inch screen because it is easy to read in bright daylight. The touchscreen feels straightforward, and I appreciate that it does not overwhelm me with too many complicated options. For me, the best part is that it gives me the essential marine information I need without making the system feel difficult to use.

Things I Considered Before Buying

When I was deciding whether the Simrad Cruise 9 was right for me, I thought about screen size, ease of use, and how well it fit my boat setup. I also wanted a unit that would let me quickly switch between measurement units, because I knew I would want knots instead of mph. For my style of boating, simplicity mattered more than having too many advanced features.

My Final Buying Advice

If I were buying the Simrad Cruise 9 again, I would still choose it for its easy operation and practical display. My advice is to make sure you understand the settings menu, especially the unit options, so you can quickly switch from mph to knots. For me, that small adjustment makes the device feel much more boat-friendly and much easier to use on the water.

Final Thoughts

I found that changing the Simrad Cruise 9 from mph to knots is a simple adjustment once you know where to look in the settings. My key takeaway is that this small change can make a big difference in how clearly I read speed data while navigating. I also think it’s worth double-checking the units after setup so my display matches the way I prefer to track speed.
