I have a couple different setups for spotting scope/tripod setups that I take depending on hunt type and animal I am after.
I have access to 3 different spotting scopes.
First is a Swaro 80mm 20-60 zoom this setup is mainly used when moose hunting which usually involves a wheeler and a boat and I use a large Manfrotto tripod with a pistol grip head. The whole setup is upwards of 9 lbs. Heavy but worth it when looking over a LOT of moose hunting and needing to count browtines up to 2 miles away...if the lighting/heatwaves/and wind allow for it.
The second setup is my main setup. Its a Zeiss Diascope 65mm 15-45 zoom weighs about 51 oz or 3.2 pounds with the Neoprene cover with a Velbon Maxi-F tripod which is about 2.2 pounds. For a total weight of 5.4 pounds. This is mainly for sheep hunting and moose hunting when not wheeler hunting when determing if a animal is legal is VERY critical.
here is a link to the velbon tripod. I like it a lot. Able to extend tall enough to be able to stand up and just it but still collaspes down to 14".

For a total setup weight much of 3.5 pounds. This is used for ultralight sheep hunting and caribou or bear hunting when determinig size is less critical. Still a great little scope, just lacks the clairty and brightness at times when compared to the Zeiss, but at nearly 2 pound savings and much more compact setup taking up less volume in the pack its worth it at times.
