We have a large pool of water quality and hydrology instruments available to you for rental.


The Torrent Board was designed by a team of hydrologists and surf board designers using the new SonTek RiverSurveyor M9 and S5 for use in high velocity conditions.

The low drag deep V keel and double concave on the board enables any entrapped air to pass either side of the instrument thus minimising aeration.

The Torrent Board has been sucessfully tested in the field by users in velocities up to 5m/s and yet still performs in low velocities as well using the supplied drag anchor.

The Torrent Board is supplied with all fixings and a handy soft case with ruck sack style straps to easily transport the board and RiverSurveyor systems across rough terrian with ease. An optional GPS tracking system can also be purchased to help location should it become lost. Likewise, a remote camera system with a ruggedised LCD can also be puchased to get a birds eye view of any objects approaching the Torrent Board whilst it is in the river helping to increase safety.
