If you want to use Devoto slider with Tomba, I suggest this way. But have on mind that according to my measurement Tomba slider is almost 50 % better in performance (energy of the shaft) than Devoto. With Tomba650 you might use Devoto slider as it is, without Tomba part. This is possible because the OD of Devoto slider is 10,5 mm and Tomba 10,7 mm - diameters are similar. But Tomba700 has OD of the slider 11,5 mm (Devoto 10,5 mm) so Devoto alone would not be good idea.

I await first shoots of fish caught on camera. :thumbsup2:

I just noticed the line hole near the front of the shaft. This system I'm familiar with. What is the function of the slider with the line on it then?
Without that micro slide on a "free shaft" a shaft deflects because of the pulling force from the shaft tip where the line is attached. This way it is more accurate. Next it behaves more similar to the regular shaft with a line slide. It is easier to retrieve the shaft after shooting in narrow places. It is also more convenient to wrap the line before loading the shaft. Without micro slide you must load the gun first, and than wrap the line round line release ...

For choosing a right Tomba (Tomba700, Tomba715...) it is very important to know the exact shaft diameter. It is not same if the shaft is 7.0 mm or 7.15 mm.
Here is a trick how can one easily take a measure of a shaft diameter without a caliper. I suppose it is clear from the picture how to make a tool and how to use it. -

Ti on the way;) will PM the track # later.

OK, thanks! :thumbsup2:

I wondered which is currently the best vacuum kit for a shaft with a slider. I believed, based on my measurement, that it might be Tomba and I was right. An Italian guy (kalama at www.pescasubacquea.net - pesca subacquea: foto, video, prede, tecniche, apnea, attrezzature, sicurezza) did some tests with the kits he had on his guns, from Mamba, STC, LGS and found Tomba to be the best in shooting performance. This was one of his last comments on a forum:
"... ps attualmente la palma di miglio kit sottovuoto testato da me tra mamba, stc, lgs, va al Tomba"
I already told that Tomba700 was even better in performance that TombaF700 (free shaft Tomba). Not a significant difference, but was better. TombaF700 is more reliable than Tomba700, (it is more simple), and maybe easier to use.
My opinion is that the best and the most reliable free shaft vacuum systems (between STC, Evo-Air, TomabaF, Tovarich) are TombaF and Tovarich. TombaF is easier to maintain, to change O-ring in muzzle despite O-ring is deeper in muzzle. -
Don, pictures are excellent! Work of artist!
I suppose you can screw it more tight than on a picture? It seems to be loose! -
