Seatec Gabbiano..extra power?

[marcomolo]

Hi guys, I don't post often here but as I've been spearfishing in ireland quite a lot this summer I'll have a bit more knowledge and also questions to share with the boards.
First, a question.
I currently have 2 guns..a Seatec Gabbiano 77 (open muzzle)with one 16mm rubber and also a Beuchat mundial 60(closed muzzle) also with a 16mm single rubbers.

When the via isn't great I take out the beuchat but most of the time I use the seatec. I can't fault either gun for accuracy, I've got good aim but I can't take all the credit.

I'm just wondering is there a way for me to add power to the gabbiano using an extra rubber or another way? Sometimes I feel the spear could do with an extra speed boost. I'm not using a reel so my range is limited by the line which I have doubled up. There's no space to add an extra rubber as the one on it is connected using the proprietary seatec system but I did find thishttp://sportsbutikken.dk/catalog/product_info.php?manufacturers_id=58&products_id=3925

Just wondering if its worth my while or should I upgrade to a longer gun with double rubbers. Bear in mind it's irish waters, not always good vis.

Thanks for any help,
Marco

The Katyusha kit is designed by Seatec for fitting a double set of bands on the Gabbiano Trb muzzle.

Maybe a 77 will come out a bit overpowered with that kit, unless you use the thin 14,5 millimeters rubbers (9/16") on it. And the tracking will not be as smooth as with the basic kit.

But if you really feel you need more power and decide to give it a go, I guess nobody can stop you right? ;-)

That does seem slightly overkill considering how relatively short my line is compared to a reel setup. She's accurate as she is so maybe I won't mess with it until i'm ready to upgrade to a bigger gun if ever!
Thanks anyway

I agree. Gabbi 77 is as good as it is.
