Yesterday I received a 2 more novataсs and unlocked them. While I was playing with them, I thought there was a useful thing - SOS and emergency strobe, which do not occupy 4 light levels, that is, you need to go into programming and turn them on and they will burn until the flashlight is turned off or the person changes the level. In modern HDS, if programming is disabled, then such a system would be rather inconvenient. But there are hidden modes - "on" simulated campfire (9 clicks from off), "on / off" locator flach (4 clicks from off), "on" true momentary (6 clicks from off), "on/off" button lockout (3 clicks pfrom off). This way we remain pretty free 5, 7, 8 clicks from off. As an example, it is rather inconvenient to install a SOS or emergency strobe or other flashing modes on a Tactical Rotary - this will greatly reduce the number of his useful levels. It seems to me that it's a good idea to cram on 5, 7, 8 clicks from off some of the most common of these modes, so as not to occupy the 4 available levels, if a person rarely uses them, but there is a probability of using them. The only thing that I remember, but cannot find in the search, one of 2 well-known representatives of HDS spoke about the limitations of the driver's memory. If so, then this way to have several additional modes can be used in a future model.
