Freediving after scuba is generally not recommended.
Spearfishing with a speargun enhances the opportunity for getting a shaft stuck in a rock, of getting tangled in the shooting line and wrapped up with the bottom, in greatly enhances the chances of exciting encounters with sharks and the exertion and distraction of stalking, landing and subduing a fish can cause a huge cascade of problems. A decent fish can swim around you, wrap a line around your neck (2-3 times), knock your mask off and slap your regulator out of your mouth - all in a few seconds. Seriously. You need to be reasonably confident you can handle this while deep and solo before you take the gun out. Starting out with a pole spear (rather than a gun) can greatly reduce the opportunities to get in trouble.
So first rule should be: no spearfishing unless you are pretty good at scuba diving - hint: your aren't "good" if you got certified yesterday - on the other hand - if you were really bad at it - you would be dead by now.
I would say 20 or 40 dives before spearfishing, minimum.
Also solo diving right out of a scuba class is pretty aggressive, but I think spearfishing (in 100 ft) is a bigger potential problem compared to solo diving. People who don't spearfish, will probably think 180 degrees from that..
So I would suggest a bunch of shallower, solo dives while not carrying a speargun is definitely called for.
Going down to 100 feet with 600 lbs to free an anchor, while solo is quite aggressive. In my opinion, you should be carrying a pony bottle when solo diving at that depth. If you had rested before the descent and made a very efficient descent and then had sufficient lift capacity in the BC to allow yourself to hold the anchor and float up- that would be doable for a very skilled and aggressive diver, assuming near zero margin for error and a pressure gauge that was exactly correct.
So going back down for a small anchor was not necessarily crazy, but it was an impudent decision and nearly caused your death. Learn from it.
The decision brings up a larger and more important issue and something they probably don't teach in a basic scuba class. When you are diving with expensive "stuff" like a speargun, light or even a camera, you need to kiss this sheeet good bye before you descend.
In other words, you should not be taking anything into the water that you are not perfectly willing to lose. That includes a POS anchor as well. A lot of accidents happen when trying to retrieve stuff, it becomes a matter of pride and determination - don't let these emotions endanger yourself.
Also, you need to set a hard limit for air supply margin for leaving the bottom. If you are solo, you don't have to worry about sharing air with some irresponsible buddy (so you can reserve less), but on the other hand you are spearfishing. Shooting a fish with 800 bs at 100 feet is far, far different from just starting to ascend. You gotta assume that any fish you shoot is going to "cost" you at least 3- 400 lbs or air to subdue- assuming all goes perfect, so you need to leave the bottom earlier (several hundred pounds earlier) when spearfishing- compared to normal solo diving. DO NOT be tempted to "shoot into" that reserve.
It's a Hero 5 I wear on my mask - had it a couple years now. I've been diving off the yak for about 3 years, but this was my first Scuba dive off it since I just bought the equipment and got certified a week and half ago.What camera do you use? How long have you had it?
How long have you been spear fishing from a kayak?
