New KISS 1 ATM Displays

These photos show some details of the new KISS 1 ATM displays. The new cases are molded from polycarbonate and Gordon has made some significant changes from the old displays.

This is a rear view of 2 of the new display housings. The individual housings interlock and are press fit together in groups of 3.

A view of the back of the housing. The circular disc in the center rotates and is currently in the ON position. The raised bar contains a magnet which triggers a reed switch when rotated to the ON or the CALIBRATE positions.

Two views of the back of the housing in the calibrate position. To rotate the disc from the OFF and position to th CALIBRATE position the spring at the right side of the case in the first photo must be pushed outward to allow the disc to rotate past the OFF position.

This spring prevents the disc from accidentally being turned to the CALIBRATE position before a dive which would result in the display flooding as the port in the back of the display is open in this position. This new design eliminates the port plug and allen key used for access to the calibration pot in the old displays.

Here is a view of the housing with the electronics and back o-ring in place. the electronics are mostly unchanged from the previous display. The reed switch has been moved to the top pf the circuit board and is enclosed which will make it much harder to damage.

The back is secured to the housing using 4 self tapping screws. The coarser thread pitch and the materials used completely eliminate the possibility of stripped threads.

Here is a side view of the assembled display.

The lens moulded into the top of the display magnifies the size of the readout.

A custom waterblock cable has been used for the displays. This cable is much tougher than the tubing and wire combo used in the old displays. It has a much thicker urathane sheath and the space between the wires and the outer sheath is filled with a viscous liquid which blocks the transfer of gas through the cable and also prevents flooding if the outer sheath of the cable is cut.

A comparison shot of the old and new KISS displays.
