Questions & Answers

SEAN C : With the BNS #4, is it possible to switch out the last bead for another mount bead, or is that only possible by buying a separate arm? For example if you buy a Sola mount tray, how can I switch to using Big blue without having to buy a whole new tray?darrick c : Hello Sean, yes you would be able to switch out the top ball with different attachments as long as the mounting balls are the same diameter.
WILLIAM K : Do these flex arms have a wire running through them to keep them from breaking away?Mario C : yes it does
Mike J : Will the  BTS Model#4 Universal Mount  work with the Big Blue VTL 4200 lights ?Mario C : Thank you for your question Mike, the light in question has 1 1/2 inch diameter and the "universal" mount will only work with diameters of 1 to 1 1/4 according to MFG. The good news is that light has the standard big blue mount, and beneath the surface confirmed to me today that they are getting ready to ship the big blue version shortly. Hope it helps dive dive dive!!
Mike J : Will the  BTS Model#4 Universal Mount  work with the Big Blue VTL 4200 lights ?DUANE C : I have the BigBlue VL4200P on my BTS universal mount and working great! Just make sure that the arms are specifically for BigBlue light mounts where the arm and lights connect.
RICHARD J : Does this flex arm work with BIG BLUE VTL4200P Dual lights ?Mario C : Yes, the BigBlue VTL4200 has the 3 prong mount on the bottom, so you have to choose the big blue light version of the BTS tray and arm set.WENCESLAO L : Yes, I am using the Big Blue VTL6000 and works perfectly.DUANE C : Yes. In fact I have several Big Blue lights that are even larger than the 4200 that I attach to the flex arms and even zip tie to the underneath portion of the Beneath the Surface baseplate. Simply unscrew the ball mount from the Big Blue light and slide one of the flex arm end that aligns correctly with the screw holes on the bottom of the Big Blue light.Jose G. M : Yes, the flex arm work perfectly with big blue lights and is very durable product. Enjoy ;-) JG

Awesome camera tray setup! Very highly recommended

This BTS dual arm mount for BigBlue dive lights was exactly what I ordered and needed for my GoPro underwater setup. The tray works easily with GoPro underwater housing and filters. The bayonet dual arms are easy to assemble making it ideal for international travelers on their dive excursions.

Excellent design

The components are very well designed and provide a great feeling about how to setup the entire tray and arms. The only small but, is in the GoPro adapter, it is a little bit lose and the gopro case move inside it making some noise you get on your sound video. I've fixed using a small elastic band.

Great Go Pro Rig

I bought this to replace my single light frame to get better photo and video lighting for my GoPro. It is well balanced and very flexible in terms of positioning the lights. I use two Bigblue AL1000WXP lights and am getting great results. The light arms detach pretty easily for packing, leaving just the flat tray base, but you will need to supply your own allen wrench.

Simple and robust

The mount was very easy to set up with the flexible arms and mount. However it would have been better if there is a standard tripod mount so that we can use a gorilla tripod for stable shots.
