Dear colleagues,
we are designing a study to record presence or absence of spider monkeys in forest fragments. We aim to record occurrences using the playback method, but we are unsure about the speaker device we should use. If you have had a similar experience and can offer some advice, I would love to hear from you!
The speaker should be able to play low-frequency calls without distortion. It should be waterproof and dustproof, wireless, and with decent battery life (usually, we have little or no access to electricity). Given that we work in very hilly areas, being light/portable is a plus.
Does any of you have used the SME-AFS Portable Field Speaker (Saul Mineroff Electronics) or the EcoBoulder Plus (ECOXGEAR)? If not, can you recommend us other brands and models?
We would be very grateful for any suggestion.
Best regards,
Irene
We used an Anchor MiniVox (Anchor, Carlsbad, CA) loudspeaker (frequency response range: 100–15000Hz, output power: 30W, Maximum SPL: 109db) for Callicebus nigrifrons. You can find more details about the procedure in this paper:

Hope it helps!
This would be a great question to post on Wildlabs.net - strong conservation tech community there that should be able to help.
I use playback with SPEAKERS of 70mm, 4Ω and 5W.
The size of speakers are very important. So the biggest the best for the quality and high volum of the sound. Those are the best i found, considering logistics of going into the forest.
Dear all,
Thank you so much for your help, it was definitely helpful! With a new field season ahead, I was wondering if anyone would be able to provide some new recommendations.
