More mamba mods!

[fer_abella]

I own an use one of these mamba 90. I use also a stealth 85.

I am a lot more interested in the new "wood handle" than the PVC pipe "mod".

How can you manufacture it and wich problems did you encounter?, specifically refering to the more difficult part, the curves in the part near to the body of gun.

The effects of water filtering the red light has been discussed at great depth elsewhere so the only thing I'm going to say is one of my guns has big bright red lettering on it, and I've been sat on the bottom in 10m and the letters were still bright red.

 

[Old Man Dave]

The filtering of red light at depth is a definite fact. Tom, you may well see red lettering at that depth as some peoples eyes are more sensetive (as are some cameras), also the filtering is effected by water clarity. Then there is the brain thing. You know the lettering is red so you see red. Actually the idea of colour is one of those philosophical arguements. How does anyone know that what they think of as red is what other people think of as red?

What I do know though is in the type of vis we generally have, certainly once you are down a bit deeper, say 50 foot, then even on the brightest clear water day and with X-ray eyes you wont see any red.

PS I'm as you know I'm as blind as a bat so what do I know?

 

[Magpie]

Oh I know its a fact Dave, I just question the depth at which it has a major effect. Your physcological point is interesting and may have had some influence, but on the occassion I'm talking about I was looking closely at the lettering to see how it changed as I dived.

But then Podges argument that fishes eyes are not sensitive to red because its not in the spectrum they usually encounter would make that all irrelevant, just like US hunters wearing bright orange because their quarry don't perceive it.

 

[foxfish]

Dave what about the light pipes we got from Podge? I could see what I thought was red at 10' for sure?

 

[Old Man Dave]

Yes, I think water clarity is the main factor in determining exactly at what depth the effect starts being noticable. Many, many times I've seen fish and my own blood run green but that has been on scuba and probably between 50 and 100 foot. Below 100 I have seen it turn black as I said before.

The shallower water usually asociated with freediving plus the lack of time to simply sit and stare probably limits the effect as well. I can't say I've ever been noticably aware of it while snorkelling except for the aforementioned effect on my orange line. However, Tom, you have actually tried to observe the effect so you have one on me there.

Be interesting to video a red rope as you dive deeper or even to try filming that red lettering. That would be an interesting experiment. Sorry got into "sad" teacher mode there for a minute :rcard.

I can take some photos to show you how tomorrow but it is not that difficult, i used a paper template & four separate pieces of wood.

 

[foxfish]

Dave it is a fact that red is the first colour to start fading but i dont know at what depth it actually becomes invisible to our eye sight? There must be many variables?

 

[Spaniard]

Red cammo is more and more common on wetsuits so must be something about it???? Red is the new black?

 

[Pastor]

Does it matter if it's the first colour to be filtered out? If fish see it as brown or something dull in the surface layers then that's what matters

 

[settingsteel]

It kinda interesting, this color thing...I always ask what does our eyes have incommon with fishes? just because we don't see red, does that neccessarily mean fish don't either- the camo thing I can relate to up to the pattern breakup, but as for the color thats a different angle.

 

[foxfish]

I tend to agree with that Tone but red camo certainly catches spearos attention!

Actually I was gonna buy me a regular wetsuit, but was told that girls really dig guys with the camo ones so I went that route instead- can't really say I have girls knocking the door down to get to me though:hmm

 

[Mr. X]

Amazing work foxfish. How do the mods improve the gun - reduce recoil?

Re. where red disappears, the location, angle, intensity and colour of the light source might also have some bearing. Don't know what "light pipes" are but if they are a light source that you carry then several of those factors will be different than a midday or setting sun, for example.

Re. Magpie's reading of red letters at depth. Did you see that program on Hypnotism & Suggestion last week? Some people are very susceptible to suggestion and it is effects colour perception. One of the tests they did was to get such a person to look at grey tones on a screen and see them in colour. Supposedly he did this under hypnothism and without, I think the effect was about 70% w/o hypnotism & about 88% with. I have pretty good eye sight & colour perception but see very little colour when diving except in the shallows where the lime green "sea lettuce" and purple aglae(?) are quite vivid.

Love the camo paintwork

Whats your mailing addy so i can send mine over for a respray LOL

 

[Mongrel454]

Also i am colourblind to a degree so it wont matter what colour i will still like it LOL
