One drawback to this unit is that there is technically no off switch. Even though the unit might not be blinking, the water sensors are active so if you are out practicing rescues or rolling with the strobe attached to your PFD, it will start blinking. It can easily be reset back to "off" mode again with the twist of the units head.
To help increase the perception of brightness, the internal microprocessor is programmed to increase the actual strobe pulse by approximately 400 times then conventional strobe lights. This increase allows the pulse to seem much brighter to the human eye, especially over long distances. We did a head-to-head test with the Intelight and a standard issue military strobe. When viewed from 250 meters away, there was quite a noticeable difference in brightness between the two units.
We did find the unit a little large. Compared to other models on the market, it is one of the largest units. For sea kayakers, it could be a little cumbersome is you plan to mount it to the back of your PFD. We did feel though that the overall brightness and reliability of it far outweighed that extra weight and size.
