Monitors with really long battery life?

2 hours ago2 hr

I normally dive on a rebreather, and now that I am getting back into underwater photography I'm looking for a monitor that has a really long battery life to add to the Nauticam housing that I recently picked up secondhand so as the monitor will last as long as the rebreather. What are the options for monitors that last longer than 2 hours? And what else do I need to know about monitors when selecting one? Are there any articles or dummies guides to selecting a monitor?

On a recent dive trip I met someone who is writing a dissertation on people who are 50+ and diving. If you are interested in contributing, the following is a link to a simple questionnaire which takes about 5 minutes to complete. I've become paranoid about online scams, phishing etc. But this looks fine and I know the author - and the information gathered is pretty innocuous. https://forms.cloud.microsoft/Pages/ResponsePage.aspx?id=e3VPRDDLUkaTvMqNbR74E5Cna1DJ6d1KvM2oRz5_gAdUM0Y3UEpYTkZERDJON

You may have read or seen pictures of the fire that broke out in the Maldives on the Emperor Explorer liveaboard on 9 May. My partner and I were on it as part of a group of 25. Like many members, we’ve been lucky enough to have been on lots of liveaboards. During the pre-departure safety briefing we were given the usual advice: If an alarm sounds do not return to our cabins to collect stuff: head immediately to the muster station by the dive platform; put together a grab bag in case of emerge

Diving with the Weefine 3000 CCW Ring Light

I have long fascinated with shooting ring lights underwater starting with the Inon Quadflash, through the various Athena modifications to Sea and Sea strobe heads, continuing to the Saga fiber optic rings and now to the Weefine 3000. The Weefine 3000 is the latest version of the LED lights made by Kraken and Weefine. The Weefine 3000 CCW Weefine 3000 CCW Ring Light It's similar to the earlier 3000 lumen LED modules but has adjustable color temperature and a 3000-lumen burst (strobe) mode. It

DIY Fibre Optic cables Like most members, when I bought my first system that used fibre optic cables, I paid for the ones that the dealers sell. Reading various articles about fibre optics, I realised later that they were relatively easy to make and that DIY cables could cost a fraction of shop-bought. I gave it a go. I thought it worth a write-up here on Waterpixels. And yes, they are really easy to make and are cheap. The Cable The best fibr
