Sun Company201-F Lev-o-gage Inclinometer | USA-Made Level Gauge for Off-Road Vehicle, Jeep, Truck, RV, Camper, Trailer, or Boat

I bought two of these. I mounted one on the dash and the other on the driver window sill. The product works as expected. I don't care for all those fancy-dancy ones that take up so much room, nor for the digital ones that are calibrated in the factory and that cannot be calibrated once they are sold.I use them off-road to get my truck as level as possible (I don't like sleeping on a slant).One with a 15 degree (30%) measurement would have been better because I don't drive anywhere that has an incline greater than that.

It is easy to mount and the included mounting tape is extremely sturdy.I find the best place to mount. This is directly over the middle of the steering wheel right in your line of vision, as shown in the picture.Obviously when you are going fast and making a turn, the bead will gravitate the opposite direction. But at rock crawling speeds, where you would actually need this, it is right on the money.It integrates well into my dash (as shown), doesn't seem to come off unless I want it to (good mounting tape included), and is accurate (compared with a level and a phone app for reference).I would buy this again and I recommend it. Just be careful out there pushing your luck on inclines!

Handy, cheap way of checking slope in the tractor on the silage pile.

These devices are similar to the old aviation turn and bank indicators which consisted of a ball in a liquid filled track. Combined with a turn indicator and a compass early fliers could confidently fly through clouds. Another historic use was on sailboats, to help trim and balance the sails by adjusting heel angle. These are sold to put on ATVs and tractors but should be used mostly as a cautionary tool and not as any hard and fast safety device. While a well sailboat can be designed to become more stable as it heels the opposite is true of a tractor. Their major safety features include counterweights, wheel weights, wide track wheels (especially not those tricycle wheels popular 80 years ago) lowering or entirely removing the front lift, carrying loads both front and back as low as possible, always prepared to dump them on the ground if they are a factor towards overbalancin, carrying the backhoe turned to the uphill side, plus seat on belts all the time and a solidly sturdy well designed ROPS which is never lowered at work, no passengers, cell phones or other distractions, Finally, rollover safety is one reason tractors have a gear shifter and 4WD. What is a safer ride through the woods in FWD first gear low range is not so safe in 2WD third gear high range. Can't use 4WD in paved areas, but these are usually flatter than unpaved areas.These instruments need a vertical surface for mounting since any forward or backward tilt changes the geometry of the ball in alcohol leveling. Unfortunately the only forward looking vertical surface I have available on the tractor is the mounting brackets for fork lift/loader but these are about an inch too narrow between metal weldments. So next best thing was to mount two of them on left and right ROPS brackets where I can see them when I can't watch the front wheels, due to backing or carrying a load.Oh, did I mention that one of my uncles died in a tractor turnover accident while clearing brush from a terraced cattle field. It was on one of those tricycle wheeled old Fords with no seat belt, no ROPS, no extra weights, maybe too much speed (about the 50th time he'd cut that same field over a lifetime) and weeds obscuring the exact pathway.

Inexpensive exact replacement for a smashed original 30 year old unit on my sailboat. Very easy installation with supplied double- sided tape.

I have one of these on my 24 year old tractor for all these years so I bought another for my new tractor. Easy and simple. Good item for safety.

Fast shipping well made easy to read nice to know what angle my skid steer is going up and down hills not worried about turning over just oil starvation

As advertised arrived on time in good condition
