The MK25 has adjustable interstage pressure anyway via the pre-load screw at the top end....the only problem with adding shims is that it raises your intermediate pressure thats ok if your spring is at the low end of the acceptable range but if it is already near the high end then a shim will likely put it over the top,just as often it is caused by harmonic resonance over the end of the piston tube and this is much more difficult to get rid of the scuba pro kits come with several different hp seats and generally a mk 25 will have a + seat i have switched to a t seat in alot of these whistlers and it has solved the problem,you may have to adjust the shimming after switching seats to get the intermediate pressure back into spec but your tech should be able to figure that out no prob.

The proposed changes have been cancelled.I went at Christmas and had my visa within 3 minutes of walking into the hall
There were quite a few empty booths, with the majority of people all using one booth as they were on a package
With any announcements to new rules / regulations it is best to wait a week or so from their announcement as a lot of decisions seem to be very elastic at the moment!!!

Yep No 1 is a great shot. Not sure what happened when i first viewed it. It was very soft but not anymore? Maybe browser hadn't finished loading the image properly.For me #1 is the definite standout wallhanger, then #6, #3, then maybe #7 (mostly for it's color)

Go tec diving where she can't follow........hahaYes, fish are frustrating but it's more the pressure of a certain recently qualified OW girlfriend that now dives with me and wants me to be with her rather than a goby. Must be the gills.
I love her to pieces but nothing sours a relationship like when you finally get focus lock on the eyes and you get shaken violently to look at a beautiful coral head she just found
How do you guys satisfy your women underwater? (Take from that what you will lol)
