  • Spearfishing flashlight ideal brightness lumens

    I don't know answer to the question of "ideal brightness" but I too use the IFL660 for peering beneath ledges or into holes during daytime. I carry it clipped to my belt. I like its compactness and the intensity of its narrow beam. My only complaint is that it doesn't have a lock to hold the switch in the off position. A couple of times the light has turned on inadvertently while on my belt, or in my gear bag, and run the batteries down. I'm gonna try to fabricate something with ShapeLock to remedy that.


    For those of you that don't mind buying used gear, the light sells for $25 at Intova's website.

    It's odd, but I notice the specs listed differ a bit between Speardiver, Intova (new) and Intova (used.)
    Speardiver shows: 220 lumens; 8 hr burn time; and 12 degree beam angle
    Intova (new) shows: 300 lumens; 3 hr burn time; and 7 degrees
    Intova (used) shows: 130-220 lumens; 5 hr burn time; and 7 degrees
    (I think the 130-220 lumens must be a typo.)


    For sporatic on/off use during daytime, the batteries last a long while. But for continuous use during night dives, you probably want to put in fresh batteries after a couple nights of use. I don't like having to buy the CR123 batteries that frequently ($$$).


    For years, my night light of choice had been UK C4 eLED. But this past year I got an Intova SL1. Now that's a BRIGHT LIGHT! Advertised as 800 lumens, 7 hr burn time, and uses 3 "C" batteries. (Much more affordable than CR123.) I mostly use the light at the reduced power setting and it's still plenty bright. Intova sells the SL1 used for $80. SL1 Search light | Intova

  • [SOLD] Speardiver C90 medium-hard blades for sale

    * * * S O L D * * *
    I bought these new from Dan last year. If you're not already familiar with these fins, search this forum and read the raving reviews. They truly are very nice performing blades. On separate occasions over the past year, I was able to compare them head-to-head with DiveR fibergalss medium stiffness, DiveR carbon-kevlar medium stiffness, and Moana soft blades, all in Mares Razor footpockets. For me personally, the C90 blades perform... noticeably better than DiveR FG ... pretty much equal to DiveR CK ... and slightly less than Moana soft blades. Actually, the Moana softs seem stiffer to me than my C90's. But, there's something about MY kicking style that causes the C90 blades to lightly brush against each other on most of my kick strokes. I don't notice that with the Moana blades.


    Anyway, mine are obviously scratched a bit, but perform good as new. $150 includes shipping

  • Best Band Combos?

    Is the band length formula "stretch factor" for small ID rubber the same as used for normal ID rubber? For normal, I usually use a stretch factor closer to 3 than 3.5. What do you guys recommend?

    What dolphin?:confused1: I didn't see no dolphin in that video - but I caught a glimpse of mermaids though :cool2:




    Just kidding about the dolphin kicking. I know what you meant. :)

  • Boat running over float line

    Quote from Andrewk

    Line only. but i found a deal on longline clips WITH swivels at basspro, 2 for less then 5 dollars. can make a float line for 10 bucks.


    Very good!


    BTW, I prefer twisted poly rope over hollow-braid for a float line. Hollow-braid is certainly simpler to splice, and is fine for bluewater unless near structure. But, my experience is twisted poly doesn't snag as quickly on structure or reef and therefore last longer. Plus it gives me a chance to practice my splicing skills - which look rather professional when I hide my flaws with heat shrink!

  • Footpocket weight and sizing

    Quote from Dan

    Water channeling begins at the footpocket with conventional footpockets, so the effect is increased. Water channeling is important for stabilizing the fin.


    Considering the speed (or lack of) that we humans swim, I imagine the difference in water channeling effect between these two designs is negligible. (does that sound engineer-ish?)
