Emily Lim –
How does the product handle exposure to wet conditions? Does it maintain its functions?
Junhao Lo –
Thank you for reaching out to us, Emily. The Ocean Reef GSM-VHF device is designed to be used in marine environments and is built with durable materials to withstand exposure to water. While it’s not completely waterproof, it does have IPX7 certification, which means it can withstand being submerged in water up to 1 meter for 30 minutes without sustaining damage. After exposure to wet conditions, the device should still maintain its functions. However, we recommend drying the device thoroughly after use in wet conditions to prevent any potential damage. We appreciate your feedback and hope this information helps!

Ryan Tan –
Will this device perform more reliably if it’s used more often? Is there anything else I should be aware of?
Imran Hanafiah –
Thank you for your review of the Ocean Reef GSM-VHF! Ryan. We appreciate your feedback and are glad you’re happy with the product. Regarding your question, the device’s reliability does improve over time as it’s used more frequently. This is because the internal components get properly exercised and configured, leading to better performance. However, please note that the GSM and VHF functionality uses mobile signal strength and provides a better signal where service providers offer these signal-strength services. It is worth mentioning that, whether you use the device more often or not the signal is going to become weaker with distance from cellular and cellular tower. We recommend using your device within a specific range for optimal results. If you have any further questions or need assistance, please don’t hesitate to contact us. We’d be happy to help.

I recently purchased the Ocean ‘smarter’ – it meets my expectations. It has a lot of features and user interface is quite intuitive, so far my experience has been solid.
