Alan,

For the video link to work you need to remove the "/," at the end

 Hi all,

 Shelley and I met Hank at Kootenay Lake to
 photo and video his modified
 Gamma
 submarine.  Unfortunately, the visibility was only about
 4-5 feet, 6
 feet at the depth of 38 feet. 
 We had great plans for recording the sub ops
 and went over diver hand signals and what to
 expect.  All for not and we
 just did as
 well as we could under the conditions available. 
 Underwater
 voice communications would have
 been most helpful.

 On the
 way out we tried hanging onto the front of the submarine at
 first,
 but this proved too difficult for the
 distance required at speed.  Shelley
 was
 holding one of the GoPro cameras and the lanyard slipped
 from her wrist
 and the camera went to the
 bottom.  We spent the next 10 minutes doing a
 search and recovery dive trying to find this
 $600 new purchase.  As what
 usually happens
 when we do a search and recovery dive, Shelley found it. 
 We
 were back in business.  I still had the
 other GoPro strapped to my head.  We
 then
 tied a couple of loops in the trailing dive safety float
 line and this
 worked out much better.  We
 felt that we could almost water ski behind this
 boat.  

 When
 we arrived over the 30 foot contour we decided to submerge
 and see what
 we could do.  We descended a
 bit faster than Hank in the sub and lost sight
 of him when more than 10 feet away.  We
 settled on the bottom and then Hank
 dropped
 out of the sky right beside us... like inches away.  All
 good.  We
 carried on with the dive as best
 we could.  You can see from the photos in
 the Psubs.org Event photos,
 http://www.psubs.org/projects/1403928245/gammakootenaylakejul15/,
 that the
 viz was pathetic.  We did not
 go deeper due to the bottom being in the way
 without being towed quite a long way off
 shore.  As it was, the built-in
 flash in
 the camera went off due to the low light, causing too much
 back
 scatter.  We really wanted to stay
 shallow so that we could use available
 light, but such is the way of things.  

 We were towed back to the
 launch ramp and after changing out of our dive
 gear I went out with Hank as a passenger.  We
 travelled further along the
 surface to the
 100 foot contour where we submerged and descended to the
 bottom.  I only had my point-and-shoot camera,
 not a GoPro for this dive
 (don't know
 why), and took a few pics out the dome.  After satiating
 ourselves with the awesome views of the mud
 bottom we surfaced and returned
 to the
 launch ramp.

 Hank's
 submarine is a most excellent vehicle.  It has enough room
 for two
 occupants to comfortably enjoy the
 view out of the amazing front dome.  The
 LED light bar lit the scene to what seemed like
 daylight.  The high level of
 battery power
 allows for a long transit and also powers the onboard
 compressor to refill the compressed air tanks
 enroute.  

 Hank has
 mastered the launch and recovery tasks with his purpose
 built
 trailer.  It is of sufficient length
 to launch the sub from most launch
 ramps,
 but it also has a large dolly wheel so that the trailer can
 be
 detached from the truck and submerged on
 a tow strap if necessary.  Hank
 installed a
 cat walk and hand rail on the forward part of the trailer
 so
 that he can easily detach the submarine
 from the trailer while he wears
 chest-waders. This allows him to tie the sub to
 the dock and then park the
 truck and
 trailer.  He can launch or recover the submarine himself in
 five
 minutes with no other help or equipment
 needed.

 It was a good time
 and the dive was good (Shelley and I do a lot of low viz
 dives).  A better viz day in the spring or
 fall would have made a more
 interesting
 photo shoot.  None the less, we had a good time.

 Tim

 Hi all,
 I went
 out to Kootenay Lake and did a dive with Tim and Shelly
 Novak
 yesterday.  I met an engineer from
 Ontario, I showed him my killer light and
 he
 said "why don't you pot the whole thing instead of
 oil filling"  Hmmm I
 had no response,
 he also said they have potted LED's for use in
 chemical
 environments.  I use a crystal
 clear casting resin for making electrical
 penetrators.  Might be worth a try.
 Hank
