gap vs. jump

[MichaelBaranowski]

I am going to be taking Cavern/intro next month with Dennis Weeks. So right now I am reading NACD Cavern & Cave Diver Workbook so I will understand much of the information be going over in the course . But a few things are confusing me a little so I figured I will ask for a little help.

What is the difference between gap and jump?

They are the same.

What is the difference between gap and jump?


A gap connects the 'gap' between two endpoints of lines (for example, connecting the lines on either side of a sink). The result is a single continuous line without any navigational decisions required on return.

A jump is jumping from one line to another line. It could make a "T" (from the middle of one line to the end of another line, or from the end to the middle). Or an "H", (from the middle of one to the middle of another).

"Jumps" require you to make a decision on which direction is the correct way to go.

Spectre,
That is kind of what I figured, but I was want to just make sure I had it correct.

Standard disclaimer, you instructor is the best person to ask this question to.

Spectre described them very well. At the Cavern and Intro levels the biggest thing to know about gaps and jumps is that you will not be doing any. This sort of complex navigation comes in to play at the Apprentice and Full levels.

You will get a huge amount of information during your Cavern class. That is the one that is really exhausting. Take your time with it, and let it all sink in.

Have fun,

I agree the instructor is the best person to ask questions but just trying to get a little info. before getting to Mexico for the course.

Reading the course workbook I get a little confusing but I will read it several times before the course and sure that I will have my head around most of the information.

It's great that you're putting some effort into preparing for your class.

I'm not an instructor, but have seen quite a few people show up for cavern classes totally unprepared. They haven't opened the book, don't have any idea what the course entails or what skills are needed, haven't been in the water for a year, etc. And then they're unhappy because they don't pass. Lots of instructors do an open water evaluation dive before taking students into the overhead, and some students don't make it past that.

All the time you spend in advance becoming familiar with the material and the skills, working on bouyancy and trim, getting comfortable with your mask off, etc. will be rewarded during your class.

Have fun, good luck!

I am a DM so I have been around many classes with students that have no idea what is going on. For my open water class I read the book 3 times before class and still not sure I was ready. I have taken classes since that I was sure to prepare not sure I was ready but then when I took the class I was so prepared that it ended up just being a fun dive.

Plus I have an addictive personality so when do something I do it over the top most of the time.

In that case, you may want to start looking for a second job :D

LOL! You betcha - cave/tech diving is a great way to get rid of any extra money you may have lying around!

I have a second job.

My day job I work 60-70 hours a week and then on weekends I work at a dive shop/scuba lake (Mammoth Lake Scuba Park). The day job I make good money and Dive shop gets me free air and a small discount on gear.

PS-Mammoth Lake Scuba park a 55 acre lake lake with over 60 wrecks and dive attractions. Including a C-130, F-5, Yellow Submarine (homemade), Several 30'+ boats, 60' Shrimp boat, Many other smaller boats (run-about), plus other thing that have been found................
