The Aztecs called them Cenotes a place of beuty.

This is the place for a sub mission for all that want to come.
The place is called Blue Springs , in central Florida close to Gennie Springs.

The very nice thing about this Spring is the huge diving deck that extends well over the mouth of the spring,look straight down and wow what a view!
Bathed in sunlight durring most of the day the rays penetrate all the way down.
You know your in clear water when the shadow of the sub is on the bottom! 8) The winter /fall and spring months are the best since kids are in school and nobody swims but the best thing is there are no divers,its not a divers cave.No body was there all to my self 8) :P
I made a movie of 30 minutes and had a blast ,so ill chop it up so that the best parts can be seen.

Next time I go Ill make external vedeos.

Also there is a wonderful beach for easy launching or a dock,plus full comforts and plenty of tables and AC power close to the spring all day admitence is 10.00$ well worth it,and to swim in is a dream at 72 degrese F.

Also a nature walk,canue rentals and camping.
Enjoy my vedeos by the way the sub performed flalessly and went all the way down at least 12 ft.A great exploration sub!

Let me know when you or a group would want to meet ,great for the winter Regatta. :wink:

Such a clear water: that's the perfect place for submariners!

Also, 12 ft down without problem is a very good performance.
Please go on, show us more...

Here are a few clips of Blue Springs Florida shot with my SB-2 Neptune ,modified to run faster and run longer and inhanced manueverability.
This Cenote is a great place for a regatta in the winter.

There will be several clips to come,also I can sell the entire movie for 15$ each.

I've noticed rust starting on the screws that hold the shell on, time to replace them with Stainless steel. Still a good value for the money.

The website for this Cenote is:

This park is very close to Genei Springs and a double visit is no problem that way both springs can be visited.

If anyone is interested in a sub run at these 2 springs let me know and we can meet.Well worth the drive!

Here is the latest modification to the Neptune its now a SB-2.
The one thing I did not like about the desighne of the drive is that there is no stuffing box Why they did that I dont know,the single lip seal unsuported by a bearring is not good or standard practice ,especialy since there is a dogbone u jount on the other side,with torque and speed it will destort the seal and a leak will ocure.Grease and oillite bearrings are instaled with a turned down brass adapter to take the place of the seal and hold the stuffing box.
The diagram is similar to what I did.

I noticed a few drops the last time I ran and it came from the seal main shaft,so I made it better.Also the water detection failsafe works very well and will shut the hole sub down till opened and dried out,just a tablespoon trigered it! But I will reposition the sensor so that it takes a bit more to activate. Will post pictures soon.

Get to the brass tacks, and install your reactor in the TT sub

Great little sub, should bring more people to the dark underwater world

Wish I could join you in Florida for the sub missions, would be fun.

It would be great to have you come down!

Internal and external switched high intensity LEDs are next for night runs and in the caves and the huge 5ft cat fish will get curiose as they cruise along side.
