Just got two of these Oxycheq Raider 3W LED backup lights to replace my current ones. Mainly, I got these to replace my older backup lights that were a bit too big on my dive harness, I wanted something a bit shorter without giving up burn-time or brightness.

These lights are bright, as bright as a 10w HID cannister light for 1/10 of the cost, i.e. $700 for a HID cannister and $70 for one of these LED backup lights.

I’m taking them on a trip in a couple of weeks and plan on putting then thru there paces.

Check out this YouTube video comparison.

This is from a couple of years ago and the video quality isn’t great but it gives a quick introduction to the KISS rebreather.

The KISS rebreathers are like the rEvo in many regards some highlights:

• Easier to travel with
• include an integrated bailout value (BOV)
• have 3-independent oxygen displays
• non-integrated harness and wing
• easy to repair as most of the parts are off-the-shelf from places like REI/HomeDepot

It lacks:

• the modular scrubber
• integrated HUD
• tool-less maintenance chassis, the KISS needs tools

These units are about the same in cost but know that both of these units are sold in units other than the USD so the price for these units fluctuates as the United States Peso Dollar moves.

I was poking around the interweb and I stumbled upon this SCUBA regulator mouth-piece: The Manta-Bite. Apparently, it’s designed to be placed in your mouth and then the “manta wings” create a water barrier.

This would allow you to relax your bite on the mouth piece and in theory make it more like breathing with your mouth slightly open.

The picture to the right shows how you pinch the mouth piece before you shove it in your mouth. I’ve read of people using these to protect their airway should they passout underwater. The thought is that with this type of mouth piece you wouldn’t lose the regulator as your jaw relaxed.

Maybe it’s comfortable but to me, it looks like it might rub my gums raw, I’d need one to review.

$39.99, available in Clear, Green and Black
