Support your underwater flash with the DELTA 3 Strobe Arm Kit with 8.0" Double Ball Middle and Top Sections from Aquatica's Technical Lighting Control series. This package gives you a 3-section arm designed for use with an underwater camera housing and tray. In addition to the two 8.0" pieces, it includes a base post that has a 1" ball for the arm and a flat plate for attachment to the grip handle on your tray.

This kit is compatible with grip handles that have 1/4"-20 mounting holes, the standard size on Aquatica housings. Three ball clamps are supplied as well, so you can connect the pieces in this kit and attach the required ball head adapter, which will vary depending on which strobe you wish to use.

The kit offers flexible support for your strobe, enabling different lighting angles and positions and allowing you to swap out the standard 1" ball arm sections for others of different lengths. If you work in close quarters or have to move your strobes in tight spaces, you'll find this ball-jointed setup suits your needs. Built to last, the components in this kit are made from aluminum that has been hard anodized and treated with Teflon for resistance to corrosion and other wear and tear.

Q: 10. I want to use this with the Canon 100-400 IS I. Do I need an extra less Plate? If so which one would you recommend?

A: Hi There,Yes, you will need an ARCA Swiss plate for this Gimble.Now, this is a good question what kind of plate you need and I can not specifically tell you since I have no such lens to try on my gimble.But I can give you some guidelines:You have a tripod leg for that lens and it has its size. I also assume that it is a fairly short leg with only one screw mount in it.Now, if you are looking for the aesthetic point of view you might be considering an ARCA plate with same length like your lens leg, but if you want to be able to play with the balance fo the camera + Lens in the gimble, I recommend you to buy a little longer plate. This will allow you to slide the plate on the gimple to find the balance position . A balance position is a position where the camera mounted on the gimble is staying balanced hands free . I know it doesn't sounds like a big deal but believe me it is more than just a nice to have .Another important point is that the plate will have the limiters both sides. Those limiters are small screws that are stopping the plate to slide off the gimble (look at the gimble image - where you put the plate - it has like two canals, one in each side).Now the next question is which plate brand should you buy. for this I have no sharp answer. I think that the brand is less important here unless it is really cheap and you fill like it is going to be unsafe to use.I have bought the below P50 plate but it was for a much bigger lens with much bigger leg.You can also see in that one that there is a screw hole at the end of the plate for the stopper/limmiter.And also make sure you are using the correct thread for your lens (1/4 or 3/8 ). if needed buy also an adapter.Hope it helps.Enjoy,Guy
