Gear Review: Brunton Omni Instruments

[@jaykennedy2411]

Been eyeballing these for about last month. Thanks again Derek!

I used a Suunto unit over 20 years ago and was incredibly accurate. Highly recommended.

[@DerekBristol]

Agreed. There are good reasons why Suuntos are the defacto standard analog cave survey instruments. Well built and accurate most of the time.

I also have OmniSignt and OmniSlope. Both have the same mechanial issues (defects) noted in this video. The user guide suggests to use both eyes when measuring. But if I do so, the reading will be off by about 5 degrees, depending on which eye is used to read the numbers. So I always use one eye and hold the device approx 5 inch. away from my face.

I contacted Brunton about this issue but my message went unanswered.

Great info! Thx

Almost seems like that inaccuracy mentioned could be a "feature" to adjust for magnetic declination? You need more than 4 degrees of adjustment though.

i dont know how to survey but i have been wanting to buy a sunnto for a few years now

Got a cheap chinese side lens capsule, it will do 1° readings as intended

I love my Apple IPhone! It’s got a GPS and a compass app 😁, I just don’t think I’d waste that kind of money on something that’s outdated and has defects. If I pay that kind of money for something, I expect quality and expect it to last!
