Brief description

The instruments on the navigation equipment console are fixed on a

pivot. The navigation instruments can therefore be set at the

required angle of vision by the user. The target is pinpointed on the

notch and bead sights on the upper side of the magnetic compass.

If necessary, the diver can always revert to the course set by the

magnetic compass on the grid ring before the dive. In this way, even

after interrupting the dive, the diver can always resume the course of

the swim set previously.

The instruments on the navigation equipment console are set at an

angle so that the magnetic compass can be held horizontally and at

eye level pointing exactly on the set course.

3

Unlike traditional instrument panels this one can be held at eye level

during the dive which guarantees that the diver can focus on

maintaining the set course since he/she does not have to switch their

gaze between the navigation instruments and the set course.

In this way using our navigation system enables deviations off the set

course during the dive to be kept to a minimum.

When not in use the instrument faces can be turned inwards and so

protected.

The instruments can be fully adjusted by means of the four allen

screws on both sides.

Diving depth gauge

Manufacturer: W. Ludolph GmbH & Co. KG, Bremerhaven / Germany

The depth gauge used in the prototype of the navigation equipment

console is being replaced with a diving depth gauge which is at present

under construction and has the following specifications:

- housing made out of seawater-proof anti-magnetic submarine

steel (according to DIN 1.3964)

- precision indicator using a membrane pressure gauge system

- adjustment of the zero point to align with different air pressures at

different depths on the back of the instrument

- scale of degrees and needle printed in luminous "afterglow"

pigment - (DTD 573)

- non-reflecting toughened glass lid

The diving depth gauge will be available with different scales for different

maximum diving depths to suit the individual user’s requirements.

Construction conforms to DIN EN 13319 which specifies operational and

safety requirements and inspection procedures for depth gauges and

combined depth gauges and chronometers.

The diving depth gauge will meet the European diving equipment

standards and will be certified by Germanischer Lloyd Hamburg.
