Garmin announces Signal VHF radios, Vesper’s DNA lives on

I’ve been waiting for this announcement for a long time. Ordinarily, VHF announcements from major marine manufacturers aren’t that exciting. Manufacturers often rely on third parties to design and build their radios. Those radios frequently just complete the line and ensure a brand matching helm. But, Garmin bought Vesper, an AIS specialist, in January of 2022. My piece covering that acquisition asked if Vesper’s innovation would continue. We’ve had to wait more than four years, but the pictures of the Signal series radios look promising.

Garmin OnBoard, slick wireless man overboard system for Garmin equipped boats

Have you ever used a traditional engine cut-off tether, forgot you were wearing it and strayed just a bit too far from the switch? I have, and it always ends the same way. The engines shut down, the boat, if it’s in gear, lurches and you’re left dead in the water. A wireless tether provides a longer and less tangle prone virtual leash to replace the physical one. Garmin is not the first company to offer a wireless tether or man overboard system, but theirs works extremely well and integrates beautifully with Garmin MFDs. So, if you have a boat with Garmin displays, this system might be for you.

SIONYX Nightwave Digital, strong low light performance with better integration

For the last 8 years, SIONYX has provided an alternative to thermal night vision cameras. They advertise the sensitivity of their Black Silicon CMOS sensor down to 0.001 LUX or total darkness. In my testing, their cameras have provided truly impressive performance while also displaying full color images in near total darkness. Impressive as their cameras have been, each review has been limited by the connectivity their cameras offered. Now, SIONYX’s Nightwave Digital offers a full suite of connectivity options. So, does the new camera provide everything I want? Read on and find out.
