The Tri-Max® by Crain is without a doubt the best instrument tripod on the market today. It’s the only surveying-grade tripod with certified accuracy – highly recommended for all servodriven and robotic total stations and 3-D laser scanners. This tripod easily meets the ISO 12858-2-H standard for the stability of instrument tripods. The revolutionary design of this tripod series and Crain’s commitment to quality mean this tripod will meet the ISO standard right out of the box, and after years of field use.

The Quick-Clamp positive locking system can be placed on the inside of the leg if needed.

The Tri-Max features a 6-5/8-inch head with large center hole (2-5/8 inch) to facilitate an easy set-up over a point. A retaining system—which prevents leg kick out and accidental falls on slick surfaces— is stored on the inside of the leg and can be left in place when the tripod is not in use. The Tri-Max features an advanced foot design. The large ‘footbed’ is there to facilitate solid planting for stability. The shape and size of the foot are designed to allow for a solid placement on any terrain. The foot is equipped with a replaceable point and a retention loop for use with a safety strap.

The Tri-Max foot plants firmly and holds tight.

The Tri-Max can handle equipment up to 65 lb (30 kg)! Number: 90550 90551 90553 90560 90561 90570
