Another push for the Profi-Six. I've had mine over 20 years, bought it new in Germany, never let me down.
A really good feature of this meter is the ability to lock the unit into a continuous metering mode, without you having to hold the button in. This is quite handy when first setting up lights with one hand and holding the meter in the other.
Normally you hold the button in and move the meter around, once you let go, the current needle setting is held for about 30 seconds, then the meter shuts off and the needle drops off to the side. This is usually enough time for you to work the dials to some possible subtle variations.
The scale works in 1/3 stop markings and you have an instant reference +- of all possible values/combinations minutes or hours of taking a reading. The scale just sits there awaiting your interpretation.
Having a needle means you can extrapolate the fine leaning of the meter towards a set value of shutter speeds and/or aperture combinations. In other words is the meter leaning towards 5.6 and 2/3rds or 5.6 and 1/3rd of a stop. With this information in front of your eyes, you can figure out whether you will be better off with f5.6 / f5.6½ / f8. This type of meter, is possibly the closest needle meter, to other meters that show LCD readings to 1/10 of a stop.
This meter also has a couple of reflected attachments which are quite cheap(ish) these days. There is the 7.5°/15° attachment, which is small, light and works a treat.
Then there is the 1°/5°/10° Profi-spot which has an adjustable dioptre correction feature. You can really use this to advantage with models, by standing back and checking either cheekbone without intruding.
The 5° setting is perfect for a whole of face reading. The clickable settings of this attachment are available whilst you look through the excellent viewfinder, with the rings giving you the correct areas being metered. I prefer the meter by itself mostly, but sometimes I'll use the spot attachment.
The spot meter attachment comes with a flexible rubber hood and a flexible rubber eyepiece, which in my case, sits on my glasses perfectly.
It is an extremely versatile meter.
