The Trident GTR is the next generation of Trident P75, further developing an already great platform. There is no other mount that comes close to the payload or precision of a Trident for the same price. 

The JTW Trident GTR further builds on the success of the P75 with additional features. The mount now includes a PEC sensor, failsafe homing, GPS, magnetic failsafe brake & optional environmental sensors.  The mount also now features internal cabling and is 25% lighter than a P75 at 30 kg mount head weight.

Addition of a PEC sensor to Direct Friction Drive is a particularly potent addition as our drive system has almost textbook periodic error, a near perfect sine-wave with 16 minute period. 

Our unique direct friction drive system combined with a mount that is designed to be easy to manufacture and maintain yields an unbeatable price/performance ratio. This mount is optimised for remote use and excels at multi-instrument payloads. 

The Trident GTR is essentially maintenance free, any part that might need replacing can be replaced in a matter of minutes, making this system ideal for remote hosting services or people who require a reliable mount with low cost of ownership.
