FAQ about Diving Accessories and Tools
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.
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.
- 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.
- 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.
- 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 polymers sold as nylon and no standards for the test methodologies, so it's impossible to compare published ratings from different sources. Our supplier tested both our Hi-Viz Dacron Line and a widely used white nylon guideline found on reels, using the same method for each test. The results show both have several hundred pounds of breaking strength, although the Hi-Viz line is stronger. Frankly, both are more than strong enough for diving purposes. Beyond strength and durability, another difference is that Dacron line exhibits significantly less elasticity than nylon.
