Frequently Asked Questions

Is the Ocean Reef SL35TX INT compatible with masks other than Ocean Reef IDMs?

This first stage is designed and built specifically for use with Ocean Reef integrated diving masks (IDMs). It is not published as compatible with other mask brands, so it should be used as part of an Ocean Reef IDM air delivery setup.

What is the difference between the SL35TX INT and the DIN version?

The SL35TX INT (SKU 9922) uses a standard INT/Yoke connection rated to 200 to 232 bar. Ocean Reef also sells the SL 35 TX DIN 300 Bar (SKU 9923), which has the same balanced diaphragm construction and specifications but uses a DIN connection rated to 300 bar instead.

Is the SL35TX INT first stage good for cold water diving?

Yes. It includes an anti-freeze kit and is suitable for cold water use below 10°C for dependable performance in low temperatures.

What is included when you buy the SL35TX INT first stage?

The SL35TX INT first stage ships as the standalone 1st Stage SL 35 TX INT unit (SKU 9922). It is intended to be connected to an Ocean Reef integrated diving mask (IDM) setup, which is sold separately.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.
