Although somewhat expensive, these are very nice warm gloves. You are always going to give up some degree of dexterity when you are using thick 7mm gloves, but these Hendersons are surprisingly flexible/stretchy. I have used these for work, in waters down to the low 40s, and they have been very good. The grip is nice, but not durable enough for grabbing lobsters, that is not what these gloves were designed for. If you destroy gloves as fast as I do, you can use tool dip (plastic grip) to help extend the life of the glove...just apply to the worn area(s) sparingly, as you will definitely lose some flexibility where this stuff is used, (also it helps if the glove is dry when you do this).
I am a golf ball diver, diving 6-10 hrs/day, 4 days a week. I have spent a small fortune in various gloves looking for something to keep my hands warm in low 50 deg water. The Hendersons are the best, they have kept my hands warm and functional even during 3hr+ dives. I do not have a Aqua Lock system on my wetsuit sleeve. I do wrap a 1.5" velcro strap or 4" wrap around the proximal opening of the glove to restrict cold water flushing in and out of the glove (this is actually minimal on these gloves, but quit substantial on others)...esp important on extended dives...when working on hookah, I am usually down for several hours/dive. On sizing, I typically wear a large, but on these I use a medium-you want a snug fit to minimize excess water in the glove (but obviously the fit should not be so tight that it restricts circulation which will also make your hands cold). The material is very stretchy which makes it comfortable and provides a surprising amount of dexterity - but at 7mm thickness probably difficult to operate a camera. The lining makes it easy to slip into when dry. When wet, I smear some baby shampoo on my hands, and slide into the gloves easily. That trick works on boots, wetsuits, etc, (I use baby shampoo as a mask defogger so I always have a bottle). I do wish these gloves had a kevlar palmar and finger surface for better durability as they are too soft for bug diving. I typically wear out gloves in about 2 weeks when working. In order to make these last, I paint high wear areas with Performix Plasti Dip. This is the stuff you dip tool handles in, you can find it in your local hardware store. Use the gloves first, in areas of wear/abrasion paint about 3 layers of the Plasti Dip - you are going to lose some flexibility and there may be some small shrinkage where you paint this stuff, so dont go too crazy, later, touch up as needed.
This is a nice weight pouch. The velcro closure does securely hold the lead shot. You can save quite a bit of money by filling these pouches with reclaimed (recycled) leadshot (available from several internet sources).
If you want a flexible boot that is easy to don/duff, has a comfortable mocassin-like fit,this boot is for you, especially at this price. The sole is very flexible, so if you are doing a lot of rock/reef scrambling to get to your dive site, this may not be a good choice. The other possible downside to this boot, is that the top does stretch out a bit with use, and it would be nice if it extended up a little higher on the leg, as water does flush in/out of the boot on occasion. The boots are comfortable enough to work in, (3-4 days a week). Since they are so flexible, I am not sure how long they will last. For rec use, they should be fine. Take my comfort comments with a grain of salt, since everyones foot shape, etc, is different.
The OTS Surface Air Valve is not a necessity, but it sure does make life a lot easier. The first month or so, I used the Mantis without the air valve. Without the valve, upon surfacing, you just have to loosen the two lower straps on the face mask to break the seal to allow ambient air in. Not really a problem, but you do need to stay calm and have 2 hands available to do this. With the air valve, you simply open the valve. The unit was easy to install, although the written instructions I were included with the valve were in Japanese. Larry Chin
