Has anyone else noticed any issues with the display? Mine seems to be a bit dim at times, even when the battery is fully charged.

Thank you for reaching out about the display issue on your Ocean Reef M-105 DIGITAL Dual Channel Transceiver Surface unit, Cecilia. We apologize if you’ve experienced any inconvenience. The display dimming could be due to various factors, including the unit’s brightness setting, battery condition, or a potential hardware issue. If you haven’t done so already, we recommend adjusting the display setting to the highest level to see if that resolves the issue. If the problem persists, please contact our customer support team so we can assist you further. We appreciate your feedback and would be happy to help.

I’m still trying to get used to the size of this thing, it’s a bit bulkier than I envisioned. Other than that, it seems to work fine. It’s not like I’m a hardcore diver or anything, so for casual dives, it’s fine.
Julian Koh –
One thing I’d like to clarify is how the dual channel transceiver works in conjunction with other devices. Does it have a specific protocol for communication or is it simply a matter of compatibility?
Junhao Lo –
Thank you for your question, Julian. The Ocean Reef M-105 DIGITAL Dual Channel Transceiver Surface unit is designed to be compatible with other devices from Ocean Reef, using their proprietary communication protocol. The device uses this protocol to establish a secure and seamless connection with other gear, enabling efficient communication. For compatibility with other brand devices, please ensure they also support this protocol or a widely accepted standard such as FM, AM, or UHF.

I’ve read that the Ocean Reef M-105 DIGITAL has some limitations in terms of depth range. Can anyone confirm this and provide any advice on how to overcome these limitations?
Imran Hanafiah –
Thank you for reaching out, Rachael. We appreciate your question about the Ocean Reef M-105 DIGITAL’s depth range. While it’s true that this unit has some limitations in terms of depth, it’s still a reliable and popular choice among divers. The recommended depth range for the M-105 is 120 feet, but some users have reported successful use at depths up to 150 feet. To overcome any limitations, we recommend ensuring proper calibrations, regular maintenance, and careful use of the unit. If you’re planning to dive beyond the recommended depth range, we recommend consulting with a diving expert or using a more advanced unit. Thank you for choosing our product, and we hope this information is helpful.
