Bosch GOL26 26X Automatic Optical Level

The x26 magnification has a very narrow field of view but allows for remarkable accuracy.

Just finished shooting a contour plot of 10 acres of orchards of mine...nearly two hundred elevation points. The level worked great. Key features I liked: 1) The view with this 26x unit is really sharp and crisp making it easy to read the rod to a tenth at up to 300 feet. I also used it as close as 20 feet and everywhere in between. 2) The auto leveling is superb...leading to quick setups and fast shoots. I used the level on a professional camera tripod equipped with a sturdy ball head and custom adapter for the level's 5/8-11mount. For each setup, I just loosened the ball head and quickly roughly-zeroed the bulls-eye level in a few seconds, fine-tuned the bulls-eye with a quick couple of turns of the levels feet, and was ready to shoot. The auto level took care of all the fine tuning for all shoot directions...very quick. 3) The auto level dampens down very fast (second or two) and didn't bounce at all in the modest winds I encountered. Very efficient shooting. 4) The focus and lateral translation knobs work very smoothly, and together with the gun-sight, make acquiring and reading the rod a quick matter. 5) I performed a full calibration of the unit before using it...it was dead nuts on as shipped from the factory. Couple of issues worth noting: 1) The level comes with a clamp to hold the auto level mechanism during transportation, but actuating it requires holding in a pin on the underside of the level. This is done automatically when the level is placed into its carrying case...thus the mechanism is clamped during transportation in its case. However, the mechanism is not clamped when carrying the unit around in the field. Having a manual clamp for field transportation could be good...OR maybe NOT so good. One would have to remember to release the clamp, or all your readings would be way off. The clamp would have to block your view or somehow force you to release it before using the instrument. It worked fine as it is. 2) In a similar manner, I had to be very careful not to take bad readings with the level by using the wrong cross hair. The level has three horizontal cross hairs: the central one and two widely spaced additional ones for use in estimating distances. A few times I caught myself using the wrong horizontal cross hair when taking a reading...they're all similar in size and color. Had to force myself to confirm that I was using the central cross hair. Bottom Line: Great Level...a pleasure to use...particularly in comparison to the old "non-auto" units I've used in the past.

J'ai acheté ce produit pour être en mesure de faire du nivellement de terrain de piscine ou de tout autre travaux en plein jour, car les niveaux laser ne sont pas en mesure de transmettre un faisceau suffisamment visible lors de journée ensoleillée. Je suis réellement satisfait de l'outil et du coffret de transport qui sont de qualité. Prix très abordable. J'ai aussi acheté le trépied Bosh qui est très bien fait. Seul point négatif: Le mode d'emploi manque de détails pour les novices comme moi. Il m'a fallu aller chercher sur Internet pour trouver un mode d'emploi plus détaillé. L'ajustement du focus doit se faire lentement pour qu'on arrive à voir l'objectif.

I'm building a house. This optical level has proved invaluable to ensure the footings and foundation walls are perfectly level. It is easy to use. Once the level is installed on the tripod (purchased separately), you center the bubble in the leveling circle as best you can and then depress the auto-leveling button, which does the minute adjustment needed to make the level perfectly level. I have a number of Bosch tools, so I purchased this device with confidence. I am very satified with it, and do recommend it for anyone looking for a good affordable optical level.

Bought for our company! Works Great!
