depending on where you dive, you will for sure see some beautiful aquatic life (dont touch) and for sure you need more weight...dont forget that !!!
 
...we dive in fresh water. Lake Fenton comes to mind, after the algea bloom in the early summer. It's kind of like diving in a biological soup! Mmmmm, Good!
 
Which gives a major difference between salt water and fresh water... the taste!
 
Vis can vary wildly in both fresh and salt water. In our part of the country, some of the best vis is in fresh water ... specifically Crescent Lake out on the Olympic Peninsula where you can typically see for 200 feet or more ... unfortunately there's just not a whole lot to look at in all that clear water. Lake Washington, on the other hand, rarely has vis better than 10-12 feet. The Sound ... which is salt water ... can vary from 50 feet to 1 foot, depending on tidal exchanges, weather, and season.

To my concern, one of the biggest differences is that when diving in fresh water you don't have to come home and rinse all the salt out of your gear ... :D

Which means that an OW certification won't cover this type dive.

Only bring this up since its on the newbie board.


Question if I may. I was givin the tables and understand them . I have also purchased a computer and it calculates altitude as well.Are you saying I would not be allowed to dive Tahoe. I don't see the problem .It was covered in my OW course.
Any views on this ?And why?

Hi all.Was just wondering what is the main difference between a salt water and fresh water dive as i am quite interested to do a fresh water dive and what kind of things can i expect to see.

On nice thing is that you don't have to rinse your gear!
 
No salt to rinse off your gear, but I still rinse off all my gear after each dive anyway. Still plenty of other contaminants in the water like algae and other creatures. Also want to make sure to minimize the transfer of things from one dive site to another. Even though zebra mussels are everywhere, no need to risk spreading them around unnecessarily.
 
diving in saltwater, depending where you go, is a pretty cool experience. there is a lot of interesting sea life and stuff to see. it's a good time

If the environment you've learned in (depth, temp, currents, altitude) determines your competency, it makes sense to extend your competency slowly, so that you are always relatively safe and prepared and in control. So, for example, new OW divers are discouraged from going to the 130' recreational diving limit without further honing of skills (and checking for narcosis) on gradually deeper dives.

A dive charter operator can set whatever requirments he/she likes, so you might or might not be allowed to join a particular event/boat/trip, depending on your rating and experience. But while (at most sites) there's nobody stopping you and your buddy from getting into the water (the oft-mentioned "dive police"), wise divers won't attempt (on their own) dives that are far outside their training and experience.

The short answer is that it is up to you to decide whether you understand the added risks and challenges of altitude diving, to own and master the necessary equipment (for example, a dive computer with appropriate altitude setting), and to decide what level of support you want when starting out.

Have fun, be safe, keep in touch!
