[mrdnyboy]

Trying to get some information on DEEPSCAN C400? When was it made,and are there any schematics still around?How does it compare to Erics other models(GOLDSCAN) .What kind of mods could be done to it, to give some of these new p.i. a run for there money?Hoping Eric, could drop a few lines in on this one being his design...any info on this P.I. would be appreciated....looks like a great classic to me!

Here's a bit of information on the Location Technology Deepscan until Eric replies.

I think it came out around 1979/80.

Three coil sizes.

Used eight of the rather large U2 batteries that fitted into the top stem of the machine.

V.C.O. pinpointing.

100% discrimination against silver paper.

Three position depth control. Select 7", 12" or 16"+ which is low, medium or high sensitivity. Select one then turn the meter knob until a zero reading obtained on the meter. Then away you go.

Rather heavy machine but all pulse were at that period due to the high battery drain requiring lots of batteries. Clever design of the handgrip with meter on top not being fixed. You could slide until the best balance was obtained then lock in position.
The stock coil was a solid disk and larger than standard machines (13" ?). This caused problems on the beach as in winter storms it acted like a sail. Also the audio was a little on the low suide. Fine for land but with crashing waves you needed good headphones with plenty of sound insulation added.

Soon followed up by the P.P.D.1, a similar design but with smaller stock coil and a ferrous/non ferrous I.D. meter.
