IST Proline

IST SPORTS Corp. was founded in 1976. The brand name IST depicts the bond among the three siblings of the founder family, namely Irene, Stanley and Tony. Over the past 30 years, the company has become a prominent scuba diving equipment manufacturer in Taiwan and gained her fair share in the market worldwide. The company spares no effort in developing, upgrading the quality of our products. Expanding new and trendy products take up quite a large part of our endeavors.

Of course, the biggest encouragement comes from the acknowledgement of some leading trading magazines such as Rodales Scuba Diving, Sport Diver, etc. In order to provide better service to our customers in the U.S.A., Mexico and dive shops in the Caribbean area, a branch office IST DIVING SYSTEM, was established in California, U.S.A. in the year of 1982.

In fact, we constantly receive encouragement from our customers and market partners especially in areas of wide variety of masks, snorkels, dive fins, neoprene products for all diving conditions, not to mention our Mini Gauges, BCD and regulators specially designed to meet professional requirements.

IST Double Hose Retainer Clip Reviews

IST Double Hose Retainer Clip Reviews

Reviewer:Billy M.on9/14/2008

These clips are great. - when we boat dive, its far easier to clip our bcs off to a floating line in the water, put on our drysuits, mask, and fins on deck, and then finish suiting up in the water. one problem that arises sometimes is that regulator hoses, computer hoses, or drysuit inflator hoses can end up tucked in behind your back or under your cumberbund. i put one clip on a d-ring on the lower part of each of my bc straps (two clips total), and clip all of the hoses to the d-rings before i begin donning the bc. inflator hose and computer hose on left, main regulator and safe-second regulator hoses on the right. now all of the hoses are kept in line with the bc straps while i fasten the cumberbund and the...

IST Sea Diver Snorkel Fins Reviews

IST Sea Diver Snorkel Fins Reviews

Reviewer:myreen a.on6/28/2007

the best fins ever!! - These light weight fins are flexible and glide you through the water. I have used this type of rubber foot fin since I discovered the joys of snorkelling 20 years ago and keep trying other types to allow me to wear swim shoes under (these are good for barefoot only) and always come back to this type of fin as my main fin to use in summer when I dont need a bootie or swim shoe or sock to keep my feet warm. this pair was for my daughter who is 10. I highly recommend this fin for anyone who swims in water that is warm enough to allow you to not have to wear a bootie or swim shoe under and conditions that dont require walking on shore to cut across barriers etc. !!!

IST Classic Round Mask Reviews

IST Classic Round Mask Reviews

Reviewer:Keith Jenkinon8/15/2008

Like the old days . . . see it all! - Ive had many masks over the years (including some very high-dollar ones) and this mask reminded me of one as a kid. You can see a huge field of view in binocular vision. Thats because there is nothing between your eyes except your nose! Objects off-center and below are seen with both eyes instead of peeping with one only eye at things not right in front. When the contemporary goggle-style masks became vogue, a big "benefit" was less air volume making it easier to purge the mask. Phooey. If you know how to purge, this mask is a snap. And, you can purge the whole mask at any angle, even swimming straight down! (That takes a little practice, but doing it while prone is easy by rotating your... View Full Review

Exactly what I expected - This product was exactly as I had expected. It is a quality piece and the shipping was prompt. Ive ordered a few thousand dollars worth of products from and have yet to be dissappointed. You are a great and very convenient source of supply.

Reviewer:Fábio Mamoru Ogawaon12/14/2013

Good - Good mask. To fix the regulator is a bit tricky, and it should have different sizes for different face sizes. Otherwise its a good product.

IST Diver´s Holster Reviews

IST Diver´s Holster Reviews

Reviewer:James W.on7/1/2011

Extra "Pockets"! - This product works GREAT! Its easy to put on, easy to take off and the two thigh pockets are big, enough and easy enought to use, to hold a spare mask, reel, slate, light or just about any other relatively small piece of gear that there just doesnt seem to be a place for. Ive shown it to several dive buddies and we basically all just go "Why didnt I think of this??". Great product at a decent price. The only question is longivity but that will be answered this dive season!
