This device is one of the lowest cost FissureMan manual suction dredge pumps offered. This is absolutely a great deal for your money if you are on a strict budget or just wish to try your luck in a stream while on that two week vacation with the family.

This device is employed to be a single stroke collection device, however, it may also be used as multi-stroke hand dredge with appropriate handling during use.
Physical size of the pump body is 1.5" ID x 18" Long (not counting the nozzle)
Mosco-ro uses a butterfly dual seal piston and therefore requires no silicone lubricants for use or maintenance. Water will be the only lubricant you really must have with this device and there will be an ample supply of that where you are going!
While one 8" x 1/2" ID nozzle pipe is provided with the
Mosco-ro , The product is being offered so that a user, with their own DIY ability, can construct additional nozzles to add whatever nozzle design/configuration wanted. All it will take is some 1/2" PVC pipe commonly found at local hardware stores to put together additional nozzles for use.

For example:

The user desires a hand dredge that requires no bending over to collect material - up to a 3 foot length of 1/2" PVC pipe can be added that will eliminate any "hunching over" to use the device.

Additionally, this sort of length allows an extended reach out into a water flow or well under a boulder that other standard hand dredges don't achieve.

Whether the user needs a short nozzle or long to access material a nozzle can be made to a length most suitable for the immediate need.

The user would like to have several nozzle lengths available - then several various or same length pieces of PVC pipe can be employed and/or attached together using suitable slip to slip fit connectors to provide a variety of lengths for various possible situations to be encountered.

Your imagination will be the only limitation when it comes to the nozzle you want to employ - a simple piece of PVC pipe purchased at your local hardware store is all that is needed for the next step of use for this versatile device.
To collect material:

Place the nozzle in close proximity or in contact with the loosened material to be collected.

Then extend the piston rod to collect and then tilt upward to maintain the material in the body.

Lower the nozzle over a collection bucket and compress the piston rod to hold the material for processing later or directly into a sluice or pan for immediate processing.

Removing any material remaining within the
Mosco-ro after your collection activity is completed is very easy. Just remove the rubberized nozzle cap to rinse out the material and the collected material easily falls right out into your pan, bucket or processing equipment.

To continue: Rinse and reattach the custom nozzle cap with the nozzle and begin again.
