The space between the lug screw and the body is so tight. it can only fit probably a very thin 1mm strap with 20mm width. 20mm width strap is too small for such a big dive comp. 1mm zulu strap is not recommended for diving. I have invented an adapter which can take up 22mm width and 1.5mm thickness. I will be selling the adapter and the strap as a package. The standard strap lenght is 30cm which is good enough for weitsuit. I will also be supplying 45cm long strap to be used with dry suit. no more extension required.
I didn't have much problem at all mounting the Geo to a 1.5mm strap. In fact I did two. Plus I put a 1mm on my wife's. The 20mm straps work perfectly on the Geo.
Why is a 1mm strap not recommended for diving? It's probably 10 times as strong as the plastic piece of crap that comes with the computer, and probably strong enough to use as a tow-strap if your dive vehicle breaks down.
