Still deciding?
How does the purchase process work?
There are two ways to purchase a Sentinel solution, depending on your needs.
Bundles
If you’re looking for a complete, ready-to-install solution, you can purchase one of our Sentinel bundles directly through our online store. Simply choose the bundle that best fits your boat and complete your purchase online.
Custom Solutions
If you have specific requirements or would like to create a custom configuration, our team can help. Simply contact us using the enquiry form, and one of our experts will guide you through the available options, recommend the right hardware and sensors, and prepare a tailored proposal for your boat.
Any proposal provided by our team is completely non-binding, allowing you to explore the best solution before making a decision.
Can I install the system myself?
Yes. Sentinel offers two installation options, allowing you to choose the approach that best fits your needs.
Professional Installation (Recommended)
The recommended option is installation by a certified Sentinel Partner. They can recommend the right configuration, ensure the system is installed correctly, and provide ongoing support if needed. Professional installation also ensures full warranty coverage and access to technical support.
Self-Installation
Selected Sentinel bundles are designed for DIY installation and include everything needed to get started. Installation guides and video tutorials are available to help you through the process.
Please note that self-installed systems may have limited warranty coverage and do not include the same level of technical support.
I have specific needs and none of the bundles exactly match what I’m looking for. What can I do?
Absolutely. While our bundles are designed around the most common boating needs, they’re not the only way to build a Sentinel solution.
If none of the available bundles match your requirements, simply contact our team through the enquiry form. A Sentinel expert will help you select the right Boat Monitor, sensors, integrations, and subscription plan to create a solution tailored to your boat and how you use it.
The consultation and proposal process is completely non-binding, allowing you to explore the available options before making a decision.
Do I need hardware to start using Sentinel?
No — you can start with Sentinel GO, the free feature set inside the app. With Sentinel GO, you can actively track trips, manage maintenance logs, complete checklists, and more without any hardware.
To try it, simply scan the QR code, download the app, and register your boat — or add the Demo Boat to experience premium features in a fully simulated mode, completely free. To unlock full boat monitoring, including battery status, sensors, tracking, and alarms, you’ll need to install Sentinel hardware and subscribe.
Can I try Sentinel before committing to a purchase?
Yes! With Sentinel GO, you can:
- Register your boat for free
- Use digital logbook & trip tracking features
- Explore premium features in demo mode
This allows you to test the Sentinel experience before investing in hardware or a subscription. Download the app and get started:
