FAQ about Diving Accessories & Tools

Compasses intended specifically for diving do not have a depth rating because they are unaffected by pressure at depth. Diving compasses are liquid filled with no compressible air space other than an insignificant tiny expansion bubble.

They differ in their responsiveness to changes in direction and their tolerance for being tilted off level. They are all similar in accurately indicating direction but their sizes affect the precision and ease with which they can be read.

  1. The generic Compact compass seen in wrist straps, hose mounts and smaller consoles is a good choice for those divers who just need to know general direction, i.e. the dive briefing is 'swim west' and you need to know which direction to swim. You have to be patient and careful to hold it level to take an accurate reading.
  2. The DGX Tech Compass offers a depth compensating bungee wrist mount preferred by most experienced divers. The compass card offers a smooth movement across a wide range of motion. It has a low profile design that is typical of diving compasses in terms of needing to be held level to take reading. Most divers find this modestly priced compass will meet their navigation needs.
  3. The DGX Deluxe Pro Compass also incorporates a bungee wrist mount and features a highly responsive compass card with a tilt potential of +/- 30°, more than most diving compasses and equal to the best versions available. The trade off to get that tolerance for tilt is the body of the compass has to be larger.
Unfortunately, there are several different types of synthetic polyamide polymers sold as nylon and no applicable standards for the test methodologies, so it's impossible to compare published ratings from different sources. Our supplier tested both our polyester line and a widely used white nylon line found on reels, using the same dry method for each test. The results show both have several hundred pounds of breaking strength, although in water our polyester round braided lines are noticeably stronger and more abrasion resistant. More information on technical characteristics is available in our Tek-Tip on Reels.

Custom manufactured for Dive Gear Express, both DGX Hi-Viz and DGX Ultra-Viz™ lines are round braided polyester with a diameter of approximately 1.8mm and are engineered high-tech products with exceptional strength, abrasion and UV resistance. The only difference is the Ultra-Viz line includes a retroreflective nylon strand impregnated with tiny glass micro-beads (<100 microns) that makes the already vibrant line even brighter. Similar to the way SOLAS tape works, when light shines on the reflective strand the light retroreflects back toward the source of the light, thus further increasing visibility.

A common misconception among divers is that stainless steel does not corrode at all. There are various types of stainless steel, each with different corrosion properties, that make a specific grade more or less suited to a particular application. All diving products made of stainless steel must receive some basic care to help minimize corrosion, more information is available in our StainLESS does not mean StainPROOF Tek-Tip.
Unfortunately, our answer regarding compatibility must be "we don't know" when we are not a service center for your equipment brand. We offer our generic service parts and tools for use only by qualified repair technicians who are able to determine compatibility for themselves using our descriptions and photographs. We do not recommend a trial and error repair strategy for life support equipment. The safe practice in circumstances of uncertainty is to contact the service department at the manufacturer. We especially recommend against DIY repairs on BC devices.

The 2nd Stage In-Line Adjusting Tool is used for fine tuning regulator 2nd stages which have an adjustable air inlet orifice that requires either either a flat blade or hex key tool to make the adjustment. Our Second Stage In-Line Adjusting Tool has BOTH an 0.032 inch flat blade, screwdriver-like adjusting tip, which fits most slotted regulator orifices and also a 5mm hex key adjusting tip plus a built-in IP gauge to verify the inter-stage pressure. To change between the two tips, the tool is easily reconfigured. To see how to reverse the tool to swap the adjusting tips, please watch the Youtube demonstration VIDEO for Second Stage In-Line Adjusting Tool.
