Ponderosa: Bringing Old School Back!

As a local Technical Cave Instructor from ProTec Dive Centres, I spend an awful amount of time at this Cenote. The reason for this is, ITS PERFECT for everything you need in a dive. If your Cavern or Intro level it has some amazing cave in the River Run. If your Full Cave and above, well it offers the perfect locations for Stage, Multi Stage and even DPV diving.

I was recently teaching a Cave/Navigation Refresher to a Full Cave diver. As we know our cave diving skills are perishable. If we don’t use it, we will lose it. So after a couple of dives at Ponderosa, we are chatting on the surface and he was like “Rob, this cave doesn’t offer much”. I laughed really, really, loudly (Yes ok again as everyone knows I laugh loudly ha ha) but I told him Ponderosa has kilometres of passageways, it’s a perfect place to cave dive, and to hone our skills as cave divers.

I got my white board out and put pen to paper so to speak. I showed him lines that he never knew existed. I told him about places you can dive whether you are SM, BM or DPV. Where you can stage/multi stages and dive for hours!


The next day he asked to go back to Ponde and for him to be shown some of these lines. On the first dive I decided to show him one such line in the cavern area. We tied in to the right and hugged the wall, descended sharply, took a right and hey presto, first line of the day. It goes right into a halocline, and it’s a pretty big cave.

If you travel on the mainline, you end up at the far end of the cavern line. It’s a pretty good circuit for beginners to complete after they are full cave trained, it is a complex circuit with 2 jumps and arrows facing in opposing directions. It’s a very silty place, with halocline pretty much all the way. You’re in fresh, then salt, then fresh, back into salt water, so it makes the dive team plan and think ahead. It also gave me chance to “wander” off the line to see how his awareness was. Great job, he caught me and told me to stay on the line.

Where the arrows go back to back, we jumped into a low silty bedding plain. Not really small just small enough for me to create a little bit of silt, to “help” him navigate his way home. It’s important to note that we were in SM configuration. So after the silt, and diminished visibility, out comes Mr Santi and now for him its lights out. He then made one of the most common mistakes by not clipping and stowing his primary light and thus leaving the light cable susceptible to entanglements. However, after a couple of reminders he did a really good job of packing it away and finding his way to the water surface. Great job dude came first … then came my debrief.

Second dive involved jumps, T’s and all in-between. I decided to take him into the River Run, jump to an unmarked jump off the main line, follow until end of line, jump to another line, and go left. When we came to the first of 3 T’s, we went right, right, and right again. At this point, I signal to the diver to hold, gave him my wet notes and I’ve already written down a question “what is the navigation to the surface” he completes the exercise, then Mr Santi comes out. Great job. He remembers his way home.

At the end of days debrief, he asks again to come back and be shown some more routes. How awesome is that, so of course we come back the next day!

As we pull up at Ponde in the morning were are discussing DPV diving and Multi Stage diving. He informs me that he would like to book a Stage class sometime, and would like to know where to dive after the Stage class. So, why not take him to the thunder cave I recently “discovered” when stage diving I thought.

Personally, I like to take the long route to this jump as it incorporates 4 jumps, so we can practice our navigation skills and team positioning skills along the way. Off we went into the river run, 1st jump right, end of line jump forward and go left, then 1st jump right after that. All jumps 1-3 executed well enough for me to be happy with them, there is always room to improve I guess, so not many notes in my wet notes for the debrief, however I did have some notes. We arrived at the EOL at jump #4. As you look at the EOL the jump is about 20m to the left midway on the wall. Just look for the dark cave that beckons you into it …

So far to date I’ve not gone far up this massive tunnel, it makes the River Run look small, therefore you could call it thunder cave right? We navigated our way down the tunnel say 10mins, we come across maybe 3 jumps already, but the darkness just keeps going. We hit thirds and turn, then he hits zero visibility. As this was his last day on the refresher course he also is the winner of an OOG diver in zero viz award, he also wins the entanglement award.

At the end of the day, sitting on the tailgate going over my wet notes, giving him his strong points, but also informing him of his weaker points, he tells me ponderosa is an amazing cave. Like I tell all my clients, we forget that these “older” caves that we train in are more than just the River Run or the Little Joe line. To be honest most cave divers and instructors do not spend enough time at these sites to really know what is there.

It seems to be the new trend to try to squeeze into new virgin cave, or visit Muyil as “I’m a sidemount diver I should dive small cave”. I always tell them, they are missing out on some awesome diving. Ponderosa is more than a training site, it is navigational heaven once you venture off the mainline, it is a DPV site, and it is a multi-stage site. By all means, please feel free to dive the caves “off the beaten track”, I do too whenever I can. However, what I am trying to say is don’t forget places like the Pit, Carwash and of course Ponde offer everything you need too.

I am currently involved in a personal project to dive these caves and learn new routes to take clients, to show you how good these sites can be. Right now in the pit I’m 3 dives into my project and I am already racking up bottom time of 19hours (CCR of course).

So you see, whatever you need, we here at ProTec can offer some advice, no matter if you dive with us or not, we are happy to give you some ideas of where to go.

Enjoy the caves, and Safe diving people!!!!!!!!!

To stage or not to stage?

I was recently assisting on a stage course alongside Patrick. We were lucky enough to be teaching a repeat guest. The guest is a solid diver, visits us a few times a year and wants to progress his education as a safe cave diver every time. Perfect. He goes away educated, trained and then gets the required hours of in water time to practice his newly found skills. He completed the course SM. The stage course is a minimum of 3 days depending on knowledge and skills in the water.

Every forum, every agency, maybe even every diver has their own opinion on ‘the stage course’. I’ve heard some divers tell me “I’m not paying for someone to teach me how to dive a stage.” My current favourite quote is when people state “there is nothing to it, clip it on breathe half the gas, and clip it off to the line”. I try to explain it’s more than that but sometimes they don’t want to listen.

The stage course is one of my favourite courses to teach and it’s high on my personal preferred ways to dive in the cave. We all as cave divers remember the importance of progressive penetration and of correct gas planning, right? For those cave divers amongst us that dive a lot and are always turning the dive on gas (when we just want to see what’s around the next bend or next tunnel), well the stage course is for you.

We are all self-proclaimed diving geeks (you know you are!). We love to set up our gear, place bungee loops here and there, pull out our wet notes and plan our next dive. Well, we do all that and more on the course.

Day one

You will learn how to correctly use a stage rig and most importantly how to set up your SM harness – if it’s not set up properly, the cave will teach you a lesson. You will learn how to correctly, safely and effectively communicate as a team during dropping and retrieval procedures and most importantly location on the cave line.

We cover finning techniques, as with a 3rd tank things get a bit tricky. We also cover touch contact in zero visibility picking up procedures. Again, these skills are lifesaving, game-changing skills. Once the classroom presentations are finished, we head off to the ‘house of pain’ or Cenote Ponderosa for some confined water torture … whoops, skills!

We set up, gear up and are in the water. Today’s skills will be those that we learned in the classroom – so trying to hover motionless and doing finning techniques is ok, except it’s a little tricky in 2m of water in a dry suit with 3 full tanks…well, tricky for everyone bar Patrick!

So three hours of skills, drills and dropping/retrieving tanks with visibility and zero visibility pass by very quickly. It’s always good to go back to basics, especially if divers have not practiced these skills for a long time.

Stage and retrieve in open water


Day two

As per normal on any ProTec course, we utilise our skill sets and past courses to continually evolve and set new bars for upcoming students from what we learnt on previous courses. So we now have free coffee to keep everyone sharp in the classroom the morning after the long day before – there’s nothing like air-con and a hot coffee to wake you up!

So we begin day two with some theory on gas/dive planning to include the extended progressive penetration grid. “What’s new?” I hear you say. This will go along side your in-depth gas planning procedures. We will mathematically show you the pros and cons of stage diving. You will cover many types of ‘gas rules’ and how to choose and apply them to stage diving. We discuss communication procedures, team, global and personal awareness. We then plan a dive to put this all into practice. So we pack up and head back to the ‘house of pain’.

All ready to go, geared up and in the water we go through our in water gear matching

We carry out a full dive briefing, descend, carry out our S Drills and begin the guests first stage cave dive…primary, secondary connection into the main line is all exactly the same. It goes well. We swim down the cavern line at Ponderosa, looking for the “jump”.   Team positioning, awareness is all exactly the same. We arrive at our “jump” – we are jumping left. The guest could not have done it better, perfect position and signals. We tie into the cave line. We swim in total for about 35mins before I signal to the leader to drop the stage.

We drop as per the classroom presentation; leader first, me second. We complete the ‘gas switch’, indicate direction of travel and move into the cave. We swim for another 45mins. The leader gives the command signal to turn the dive, I repeat. Then the fun begins…

The guest is given multiple failures and free flows with and without visibility. It goes to show, if you receive the correct training, you can overcome any failures. There was as usual a lot to discuss on the debrief, after all we did an awesome 3 hour cave dive to the chapel and back from Ponderosa. If you have not seen this part of the cave yet, I would highly recommend it.

Cave procedures


“At last day three”

This was the guest’s words over coffee that morning ha ha. So today was exactly the same as day two and we planned a dive at cenote Taj Ma Ha, followed the same procedure setting up, in water brief, S Drills and off we went. We have all dived ‘Taj’ right – but super shallow, in a dry suit with 3 tanks is a little ‘challenging’ as we all know.

We tie in, make a good secondary and off we go, down the slope. We tie into the main line in ‘pole position’. We swim along the main line until our designated jump. We reach our stage pressure and we drop. Remembering his training, the team selects the correct place to drop the stage and the team form up using the line as a reference. The gas switch procedure is followed to the letter and off we go for the rest of the dive. Needless to say it was another 3 hours of fun! Small passages, big passages, white cave and dark cave. We practised Zero visibility, free flows and 1st and 2nd stage issues. It was awesome.

What was not awesome was my mask breaking 30mins into the dive (yes I know, 1 in a million eh) – the strap broke so I referenced the line, alerted my buddy, closed my eyes and felt for my rear pocket and replaced my mask. All good you’re thinking right?……nope! I forgot to prepare my mask before the dive so every second it fogged up (that’s what it felt like) it was awful, plus all the skills and drills. I longed for the blackout mask that day ha ha.

Again, we had an in-depth brief on the surface, calculated all our information from the extended progressive penetration grid and figured out that we actually have a good gas consumption, so we survived todays dive, even with a fogged up mask.

Zero vis exits and stage retrieval

For me, to teach this course or to be a student on this course means the same thing. Going back to basics learning, really learning the skills we all learned on the cave course and then just taking it to the next level. The stage course is more than just ‘taking a 3rd tank, and clipping it to the line’. Cave diving is inherently dangerous and diving beyond ones certification is dangerous right? Receiving not just training, but good solid training is the smartest thing of all. Once stage certified, your cave diving will be taken to the next level. Overall, 3 days and a total of 9 hours in the water – can’t be bad eh!!
