Kit review: IST Rubber Jet Fins

18 01 2012
We’re really keen to hear from our members about their favourite pieces of dive kit, and first up we’ve got a great review and useful recommendation from Mark Hammond.
 
In the years I’ve been diving, I’ve often noticed a number of divers trundling off to their local dive site with the latest and sometimes very expensive fins, ankle weights in tow.
 
After every dive, I always hear the same story: ‘I struggled with my buoyancy, I kicked the sand up, my legs are tired’ and so on.
 
I must confess I had exactly the same problems until I spoke to a commercial diver who set me on the straight and narrow – he advised me to get rid of my long floppy expensive fins, get rid of my ankle weights, and to purchase a pair of jet fins.
 
Jet fins were developed some time ago for the US Navy Seals, but since the patent ran out a number of manufactures make them including Scubapro, IST and Poseidon. I thought the fins I had were already jet fins, but he then showed me a pair of IST rubber fins, which he’d been using for a long time.
 
Initially I thought they were quite heavy, but he explained that I could now dump my ankle weights, and because they have vents on the back stroke, I wouldn’t be moving as much water – the water passes through the vents and you don’t have to work so hard.
 
Better still, they’re short so you don’t kick up the sea bed, they grip well in a current, I can frog fin with ease, and they are very robust.
 
Having owned a pair for three years, I’d never contemplate changing them. It was probably the best £40 I’ve ever spent on dive kit!

How a depth gauge is made

23 02 2011

Ever wondered how parts of your scuba kit are made? We continue our look at the technology behind the gear with Scuba Engineering’s series of vids on YouTube.

We’ve already seen how a regulator is made and how an aluminium tank is made, but here we get to see how to make a depth gauge.

Watch the video on Scuba Engineering’s YouTube channel to find out what’s behind the making of this essential piece of equipment.





How scuba regs are made

Continuing our look at how scuba equipment is made, today’s video shows in extraordinary detail the complex process behind making regulators.

Don’t forget to check out last week’s video showing how cylinders are made, and next week we’ll be posting another video from the Scuba Engineering channel showing how a depth gauge is made.

A quick video to share with you this evening, for those who have ever wondered how your cylinder was made!

Wonder no more – there’s a great channel on YouTube by Scuba Engineering that shows us how a dive-safe aluminium scuba tank is put together from start to finish.

Does your kit need some TLC?

2 03 2010

It’s a bit nippy for diving at the mo, unless you’re a) Troy, or b) one of the lucky few booked on our Club Trip to Egypt trip next week.

The winter months are, therefore, the perfect time to thoroughly check your kit and replace any damaged or missing parts.

We all know how the smallest problems can have a much more significant impact, so it’s vitally important to ensure you take good care of your equipment.

The UK Divers website has some fantastic tips on how to rinse and store your gear after use, as well as suggestions for checking your O-rings and ensuring that no particles have got into any valves or seals.

If you’re relatively new to diving and about to invest in some new equipment, they also have a very comprehensive section on what to look out for, which you can see here.

Definitely worth a visit when you get chance!
