Man ... price is all over the board on this one. Since I sell a lot of seals to the shops, I see everything from about a $35 DIY to over $100.

I suggest that you take it to someone that has done a few of them so that it gets done right the first time.

Good hunting!

For those that remember Horizon Watersports in Beaverton, the owner, Bob Brown passed away on Monday. Bob has been managing a resort in the South Pacific since closing up the shop last year. I first met him when he was just a manager at a dive shop and followed him through his different phases of ow...

Not to take away or change direction from Amy's thread, but I can give a little insight into the standard little compressors as well. Yes, 155 VAC is nice. However, it is the slowest running motor of all the options available and that makes a 3.5 CFM machine only put out 2.8 CFM. Additionally, it ha...

Yes, there is a device that suction cups to the inside of the mask and holds the glasses (less the arms) to the inside of the mask.

One thing you could try is to put a tiny pea sized blob of tooth paste in your cheek. The minty flavor will cause you to salivate and eliminate the dry mouth.

Now, I DID NOT say to put a mint in your mouth! It might inhaled and then where you be!?[-X

CT is absolutely right! The valve just has to be screwed in to the point that it "kisses" the tank. That insures that the O-ring is captured. Once pressure is applied, the o-ring is pressed into the sealing area of the valve and tank and "locks" them together. Dive shops used to ...

Undergarments can only trap so much air. After they are "saturated" with air, all extra air gathers at the highest point on the body in the form of bubbles. It's these bubbles that have caused so much trouble to new (or clueless) drysuit divers. It is important for us to find out just exac...

Using both for control is much more complicated than just using one or the other. In a shell style suit, when the proper weight is worn for neutral buoyancy, insulation directly tracks buoyancy. As you go down, the air compresses and you lose insulation and buoyancy. Touch the inflater to restore yo...
