Dual strobes??

[Regulus]

It was recommended to me to use a HID or modeling light with a diffuser as a dive light in conjunction with a strobe.

Haven't tried it yet. Any comments of this approach?

Good luck

A flashlight is good if you need more light to focus. But it won't help much with the exposure. Even a very bright HID puts out nowhere near as much light as does a strobe. With high shutter speeds you won't see the flashlight light at all.
