Is the COLT supplied with a case? Yes, COLT is supplied with an aluminum flight case with a purpose moulded internal foam to keep the product, spare batteries, the CVT calibration rod, and your wire diameter measuring tool safe while you are on the move.


What does drop tested mean? During development and part of the approval process with Crown Castle, American Tower, and NATE it was necessary to ensure that the COLT could withstand and maintain accuracy when dropped. So the product was dropped multiple times at different angles from a height of 10 feet or 3 meters onto a solid concrete base. After each session of drop tests the COLT was tested for accuracy — and passed!


Do I need to change sheaves if i switch rope diameter like other products on the market? No, the COLT’s unique design means that only the sheaves that are fitted to the product during assemble are needed for any rope up to 1 inch diameter. The adjustment for different rope diameters is done by a quick adjustment of the center sheave height from positions 1, 2 and 3 — it takes seconds.


How many wire ropes are stored on the COLT? This is the clever part: all the wire ropes in the database are stored on a cloud server; when you install the app it downloads the database. As Straightpoint add new wire ropes to the database, you will get those added to your app also.


What if the wire rope I am using is not held in the database? Easy: get a 10 foot sample to Straightpoint and they will add it — Free of charge!


What else does the app do? As well as measuring the load it also data logs it into a report that also includes local weather conditions and GP coordinates of where the job took place. If measuring guy lines the app will allow you to set up how many lines or legs are to be measured and then after measurement tell you what the adjustments to balance the loads should be.


Is the app expensive? No, its Free! You can download for iOS or Android devices and it even has a simulate mode so you can try the app before your purchase the COLT tensionmeter.


What if I don’t want to hold my smartphone when i am using the COLT? Another easy one: the COLT is supplied with a cellphone holder so you can clip the phone straight onto the COLT and free up both hands to measure or adjust.
