Wetpixel Live: Pimping your Strobe

@Alex_Mustard and @adamhanlon chat through a  wide range of strobe accessories. Our goal as underwater photographers is to capture light, so anything we can do to improve or modify our flashes' output can provide great benefits and significantly improve our images.

I have a question regarding this nice video:

At approx 08:00 Alex demonstrates snoots at different diameters available for the Retra strobe. Later, at approx. 10:20 the Retra LSD.

My question: Is the LSD just the better, "luxury", version at a higher weight, or are there different applications for the snoots and the LSD (e.g. narrowing the beam to reduce backscatter for the snoots and "creative" lighting for the LSD)?

I am asking, since I consider the acquisition of a snoot for our Inon Z330's (no experience with snoots, so far):

This here that looks similar to the traditional snoot shown in the video: https://www.panoceanphoto.com/inon-snoot-set-z-330-d-200

or the Retra LSD in Inon Z330 mount: https://www.retra-uwt.com/collections/shop/products/light-shaping-device?variant=12730263240746

Is it advisable to go just for the LSD and one has then everything, or should one have both snoot plus LSD for different applications (also the size and weight of the LSD may be worth a consideration)?

Thanks for ideas, Wolfgang

I guess you although you could define the beam restrictors as "snoots," but they are really used for controlling the angle of light from the strobe, rather than providing a single tightly focused narrow beam of it.

In terms of use, I tend to use beam restrictors for controlling how the light falls off for wide-angle photography whereas the LSD (or what I would define as a "snoot") is very much a macro tool.
