The Phreatic Zone

Having seen one of these bad boys in action on Cave 1, this was my first close look….and first impressions were good!

They have a more robust feel than that of the Halcyon Scout or scout copies i.e Photon or Solaris with the added security of a 2nd O-Ring, deeply knurled handle and a heat dissipation tube inside.

Instructions, spare O-Rings and catalyst pellets for NiMh cells

And again, Heser on left

Beam Pattern taken from 10M, Heser on right

Unfortuantely I do not have any footage of the heser versus rivals underwater, but I can assure you of one thing…..There really is no comparison for burntime, beam and colour temperature!!

The Halcyon Scout LED upgrade will cost you £88 each, added to the £59 for the standard scout which weights in at a hefty £147 per backup!

The heser is £110 to your door through Jack@dublinbaydiving.com

AGIR wings are the first wings designed specifically for European (e.g. Faber) double cylinders. They have the lift capacity of 38lbs / 17,3kg and 56lbs / 26kg. They are designed for use with medium- to heavyweight doubles together with aluminium deco cylinders and “common divegear”.

habrok- has fast become popular among divers (not just techdivers), who want comfortable and perfect trim both swimming and / or on deco. The design itself gives great stability, and prevents front tip over.

Additional advantages:

Short zip, not one inch more than necessary. A zip is a weak point, so it´s minimal.

Room enough for the backplate. It will not be squeezed to the cylinders.

Several holes for finding the right trim.

Rubber protection under the zip to avoid impact damages.

Cover made of nylon coated cordura

Innerbladder of strong 420 denier “puncturesafe” cordura lifejacket fabric.

Thicker cord to dumpvalve for easy grip.

The OPRV (dump) is placed to give best performance,
then used get the right leveltrim.

Wikiscuba is a project to create a free, complete and up to date Scuba Diving Reference Guide. It is a fully collaborative project between wikidivers from around the world. 

The current wikiscuba project originates from the fusion of two independent projects. One was started in November 2005 by Charles at wikiscuba.org. Inspired by wikitravel, it aimed at creating a complete scuba diving travel guide. The second project was started by Andy in January 2006, at wikiscuba.com, and was inspired by two sites, Wikipedia, the free encyclopedia, and also Wikitravel, the world-wide travel guide. The two projects were merged in February of 2006 to create the current wikiscuba project, now available under both wikiscuba.org and wikiscuba.com, as well as the .net extension.

Wikiscuba is an attempt to build a completely free and open reference guide for scuba diving, including;

• equipment guides and reference materials
• science and physics of diving
• international diving sites

The aim is to present a factual and objective resource for all scuba divers around the globe. Our copyleft license means that the facts within Wikiscuba are available to all, for free.

The software we use for this wiki is Wikimedia, the same used by wikipedia and wikitravel, which lets any internet reader create, update and edit and illustrate any article on the website. Everyone and anyone can contribute information to the website as long as it complies with our Wikiscuba:Neutral point of view policy. The more people that contribute, the more complete the reference guide.

For all your Technical diving needs including Twinsets, Agir Brokk, Heser, Salvo and gavin scooters,etc
