Clips are cool looking but can be a little tricky to deal with. Below are pics of an old fashioned end cutter which has been modified. The sides have been reduced and the face has been flattened with a grinder. This nipper is 7.5 inches length and will remove a box clip in one stroke. It may...

It's a new G250HP which I have fine tuned. It is connected to a US Divers SEA with 1/2 inch hi-flow hose. The 2nd stage functions normally until the hose nut is tightened. Tightening the hose nut with a wrench is followed by a slight free flow from the G250HP. If the nut is backed off slightly...

I clicked "vintagedoublehose.com" and got a plumbing store. What's up?

My NITROX stik is monitored by a Miniox III. The display of this oxygen analyzer stays on even when the box itself is turned off; in other words, the display reads "off" and this draws a small amount of current all the time. After a few months, it is necessary to replace the battery regardless...

Not long ago, physicians believed that the human CNS could not repair itself. However, recently, it has come to light that this may be wrong as there has been evidence of the brain repairing itself as opposed to "rearranging the furniture", er, circuits. Some divers with type II DCS have...

I've had this mask for two years, a copy of the SP Frameless. It is a very high quality mask but it fogs up. On the boat, spit had no effect whatsoever. Joy detergent worked for 1/2 hour if the mask also had the saliva treatment. I've never used a mask that absolutely will not break in, not...

I bought an "egg carton" rack on EBay and converted it for use with 6.9 steel cylinders. Outriggers were added for stability on board. I haven't tested it yet so don't know if it will crab walk in choppy seas. If so, might require a lashing. Don't anticipate any real problems. Very light to...

My pics will not download on SB. They did in the past. The pics will still load into Yahoo, etc. After about a minute of attempting to load on SB using "manage attachments" SB says "there was an error". I have a dial up connection and am using the same camera, etc, same settings. :huh:

The new "X" fin is advertised as having an "upgrade". I found no reference in their advertising or Rodales, or from Dema reports as to what was meant by this. I inquired of Oceanic as to what the upgrade consisted of. After a couple of Emails back and forth, they divulged that the upgrade is...
